How to grow Australian crayfish for breeding?

Breeding crayfish as a business is a new, yet uncompetitive topic in the business world, but it is rapidly gaining momentum. It is especially understandable and pleasant for farmers or summer residents who have both an area and a hectare where they can "roam" and bring such an interesting business idea to life.

Breeding types of crayfish

To start breeding crayfish, it is enough to purchase adult females and males (in proportions of 2: 1 or 3: 1) from lovers of river fishing or in large fishing companies for breeding crayfish (specialized fish farms), taking into account that for further reproduction, females can lay 100 eggs.

Types of crayfish for breeding:

• Australian cancer - the fleshy and most suitable for breeding at home on artificial temperature maintenance, namely in an aquarium.
• Marble cancer - suitable for growing, like the Australian, in special conditions and warm water. Reproduces in the same-sex way (parthenogenesis).
• Armenian and Altai crayfish - based on the reviews of farmers in Russia, both in taste and in breeding are the most popular.

• Long-toed European - a breed of crayfish, fast growing and well adaptable to any conditions.

In all crayfish specimens, fry must be deposited so that they do not suffer from cannibalism.

Breeding crayfish in an aquarium or pool

If you do not have the opportunity to grow crayfish in natural conditions (or there is no way to create such conditions, for example, a pond) or your climate is too cold for this fishery, then you can use aquariums for this.

What you need to grow crayfish in an aquarium:

• A well-heated room with a closed water supply system, the room temperature should not be lower than 15 degrees for the normal life of your "pets".
• Pools with a volume of at least 250 liters of water are better large in area and not very high in order to reduce the density of crayfish per square meter (assumed density is no more than 50 crayfish per 250 liter pool).
• Plastic pipes, cut to a length of 20 cm (during molting, crayfish can eat their "brothers", so you need to provide them with shelter).
• Aerator for oxygenation of the aquarium.
• Catchers and special devices for the transport of crayfish.
• You can use special "feeders" for crayfish so that after the leftovers from feeding the pool (aquarium) does not become dirty.
• The temperature of the running water in the pool should be 5 degrees. These are optimal conditions not only for overexposure of cancer, but also for the cancer to become active in search of food and shed.

Aquariums are good not only because they save the farmer from inconvenience, but also because they can set the required temperature for more active growth of crayfish, their reproduction and weight gain, which, therefore, will bring an increase in the turnover of your business. Well, it should be said about the absence of "wintering" in crayfish grown in an aquarium, which will bring the entrepreneur a profit faster.

Business plan for breeding crayfish in an aquarium

To breed crayfish in aquariums, you will need special equipment:

• The actual pools (aquariums). Pools for summer cottage use are also suitable here (if they are frame - it is necessary to exclude contact of the frame with water, so as not to change the usual habitat of crayfish) - about 200,000 rubles for 4 pieces.
• Pool aerators - 60,000 rubles.
• Oxygen generator mainly for young animals - 70,000 rubles.
• Various devices for measuring water quality - an oximeter - 20,000 rubles, a special device with the functions of a conductometer, salt meter and thermometer - 7,000 rubles.
• Meals for six months - 20,000 rubles.

Total costs for a year of doing business will amount to about 450,000 rubles. For the next year, costs will decrease significantly, and the productivity of crayfish will increase. Therefore, a business plan for removing crayfish is considered quite cost-effective and pays off in 2 years. If you don't know what a business plan is, then read this article.

Breeding crayfish in water bodies or ponds

If you have the opportunity to organize your own reservoir for breeding crayfish - use it! An artificial reservoir "to build" is not as difficult as it might seem at first glance:

1. It is necessary to dig a pond with a depth of 2 meters and an area of ​​about 15 squares. At the same time, there will be about four such reservoirs for big business. You can also create a pond using a waterproofing film that has a lifespan of 20 years or more.
2. The bottom can be covered with soil or a mixture of soil and sand, and also take care of the presence of driftwood and stones, grottoes, burrows and small shelters - - means for "hide and seek" crayfish from attackers.
3. It is necessary to make a drainage system: from above there is a pipe with a valve, and in the transition to the reservoir, the pipe should be closed with a mesh so that the crayfish do not rush "to the exit".
4. From above, you can fill in water, and you can update the running water no more than 30%, so as not to change the microclimate of the pond. From its change, cancers can hurt, and this knocks down not one individual, but several at once.
5. Good filtration and aeration (crayfish love clean water).
6. Fences for small crustaceans, juveniles and ready for sale. Fences should be fine-mesh.

As good as the idea of ​​growing crayfish naturally, it also has its own characteristics:

• The pond should be in the shade - crayfish do not tolerate heat very well. And since the required area is not small, most likely, you will have to install industrial greenhouses or used in horticultural farms.
• For high-quality cultivation of crayfish in a pond, as in an aquarium, it is necessary to install a compressor to prevent water stagnation, an oxidizer and a filtration system.
• It is advisable that all your "water structures" are located on your territory, and not outside it, as lovers of easy money can also really like your idea.

If crayfish are grown in natural reservoirs, then they undergo molting from spring to the end of August in heated water, have a soft shell and remain small in size. Crayfish reach their "apogee" both in growth and taste in the autumn period.

Crayfish can be fed with:

• Worms, insect larvae, snails.
• Vegetables (potatoes and carrots).
• Specialized compound feed.

Moreover, if you give crayfish "home" food, it must be crushed and fed several times a day. For small crustaceans, the best feed is compound feed with minerals and vitamins.

Business plan for breeding crayfish in a pond

Breeding crayfish in a pond is a cheaper option compared to an aquarium one. This does not take into account purchases related to business expansion. And so, to breed individuals in a pond, you will need:

• 500 individuals, which will cost at least 20,000 rubles when purchasing.
• The cost of organizing a reservoir will cost you from 40,000 to 70,000 rubles, depending on the area and the materials used.
• From these individuals during the season you will receive about 17,500-18,000 crayfish, if we take into account the weight of the crayfish in 300 grams, then the output per season will be about 5500 kg.
• If we take the minimum cost per kilogram of 200 rubles, then with full implementation, you can get an income of 1,100,000 rubles.

That is, at a cost of 100,000 rubles, the profit will be 1,000,000 rubles, all this is rough, but it still works!

In any case, for the pond, all expensive purchases should lie in adjusting the business plan - first you need to make sure that things go well. And the best option is and remains a combination of the aquarium method and a pond - crustaceans are grown in aquariums, and larger individuals are already planted in the pond.

How to draw up business plans correctly is described in the next article.

Distribution channels for the cancer industry

An important point when engaging in such a business is to analyze the sales channels of products and possible competitors.

As a rule, it is free with competitors, especially when organizing a serious business. Therefore, to begin with:

• Inspect: Restaurants, bars and cafes are places where crayfish supply is required. How would they like to receive products? Many people require already boiled crayfish - you will know that you need to take care of this and conclude a supply agreement in advance.
• Grocery stores and large retail chains are also interested in receiving quality products in raw and finished form.
• The market is a place where there is always a demand for crayfish, and since there is most likely more than one market in your city, or even if there is a possibility of supply to nearby villages and villages!
• You can promote your business yourself using a virtual platform. For example, a farmer in a video not only talked about his farm, but also posted a video on YouTube, which contributes to a quick promotion! Think for yourself, if you have a website and groups that can be advertised on the pages of the institutions you need in your city, the people themselves will reach out to you.

Arrange "excursions" to your farm! Naturally, there should be cleanliness and order, but this will first attract small residents, and then their parents for a purchase.

Starting a crayfish breeding business from the legal side

If you decide to organize such a business, the most successful option here would be to open an individual entrepreneur, and for taxation you can use the Unified Agricultural Tax, since this type of business is related to agricultural activity.

And here there are several aspects regarding the "construction" of a natural reservoir:

• If you own a piece of land as an owner, you can create ponds and pools. It should be remembered that the pond should not be deeper than 5 meters. If you rent this piece of land, you will have to go through many instances in order to get the right to implement your business project.
• It is very important in this matter that the self-made pond (s) should not be connected to natural water bodies that belong to federal property.

For the sale of live crayfish, there are rules, within the framework of which you must obtain the following permits:

• Veterinary certificate and sanitary certificate at the veterinary station;
• Certification of activities in the Rosselkhoznadzor;
• Declaration of Conformity in the Rosselkhoznadzor branch or in other structures accredited in this area.

Video instructions for growing crayfish

In this video, you can watch how crayfish are grown indoors, in which production is extremely successful and has already been put on stream. It describes the conditions for keeping crayfish, the specifics of this business and why it is quite profitable to deal with specifically Australian crustaceans.

In this video, you can see just the most popular combined crayfish breeding method, which allows you to separately raise the offspring of crayfish in indoor pools and aquariums, and then send them to their natural habitat - a pond. It also tells about the peculiarities of this process, so that the crustaceans feel "at home" in the new environment.

Breeding crayfish can be a pretty profitable business that can generate income. The main thing is to worry in advance about the sale of products, to calculate costs and potential profits.And strive for the set result! Remember, in 2 years a business can become profitable, and this depends not only on your concern for your "brainchild", but also on your ability to conduct an advertising campaign.

2. Breeding of Australian crayfish together with other species.
3. Features of the content of Australian crayfish.

Breeding Australian crayfish at home possible only in certain containers.

In general, it is worth noting that it is much easier to care for and keep crayfish of this breed than ordinary ones. For a comfortable habitat of crayfish, they need to be provided with a container or an aquarium, the volume of which will be at least two hundred liters. It is also important to know that to keep one pair of Australian crayfish at home, you need at least 150 liters of water. The water itself should be hard, it is more suitable for their habitat. But if the water is soft, the crayfish will still survive.

Growing Australian crayfish at home

A very important and even a prerequisite for the comfortable keeping of these crayfish is the presence of bright decorations. Australian crayfish very often arrange colored decorations at their discretion, and therefore such stones, flowers, etc. must be in the container. In addition to decorations, such stones will act as a territory delimiter for the crayfish themselves. To this should be added also places where pets can hide. If there are few or no such places, then it is quite possible that conflicts between cancers will begin. Ceramic pipes or pots, some driftwood, etc. may be suitable as a shelter. It is best to have several such shelters per inhabitant. Regular large stones, by the way, will not work for them. In addition to shelters and decorations, crayfish are engaged in digging holes or holes, and therefore there must be a layer of soil in the aquarium for these activities.

There is one more condition that is optional, but desirable for the performance and comfort of pets. Such a condition is that the cancer must have a way out of the water. But at the same time, it is worth remembering that if there is a cat in the house, then you need to make sure that he does not get to the cancer during a walk.

In addition, you need to leave a small empty space at the bottom of the container. This is necessary so that the cancer can shed its old shell.

Breeding Australian crayfish with other species

Breeding Australian crayfish in aquarium conditions is also possible with neighbors from other species.

In addition to the fact that other fish in the tank may simply be pleasing to the eye, there is a better reason for keeping them in the same tank along with crayfish. The reason for this is that some species of fish, such as guppies, for example, can scavenge crayfish waste. If you do not have such fish or do not clean the aquarium, there can be outbreaks of disease, from which the pets will die. The only disadvantage that will affect only small fish is overeating, since they do not know how to restrain themselves. But do not worry, even if the fish dies, in which case the crayfish will play the role of orderlies. A small disadvantage may be that crayfish can injure the fish if it starts stealing food.

However, do not overdo it, it is better to buy a lot of small and fast-breeding fish than a few large ones. Large fish can eat small crustaceans, which should not be allowed. In addition, snails and shrimps will be unwanted companions for crayfish.

Growing Australian crayfish at home requires certain vegetation in a container with crayfish. It is worth noting that this type of crayfish is very fond of eating greens, and therefore everything that they find will be eaten. If there is a need to simply decorate the container with crayfish, then it is best to add plants that are able to float above the water.The best option would be to have another container in which the plants will be grown, and then transplanted into an aquarium with crayfish.

The most suitable plant would be klidiflora. It will last for a long time. Another great plant would be duckweed. This type of greenery spreads very quickly throughout the aquarium and the crayfish do not have time to eat it all. In order to create comfort for small and young crustaceans, you can stock up on such a plant as floss. You can even bring it from a natural pond, but at the same time you need to be careful and not infect all living things in the container. The filament will be a great place for small crustaceans, as they love to eat it, swarming in it.

Features of the content of Australian crayfish

The breed of these crayfish is not very demanding for the purity of the water itself. Australian crayfish do a pretty good job of dealing with temperature swings, but there are still a few criteria to watch out for:

1. The temperature in the aquarium should not drop below +18 degrees Celsius. If this temperature is allowed and not raised in a short time, the crayfish will die;
2. The optimal degree of water will be from +20 to +26;
3. In the summer, when the water in the aquarium can heat up to +30 degrees Celsius, it is necessary to ensure that the water is saturated with oxygen.

In addition to maintaining a certain temperature in the aquarium, you need to ensure that the crayfish eat certain foods. Although these creatures are naturally vegetarians, they can eat creatures such as:

• Small fish;
• Frogs;
• Snails.

If we talk about vegetarian food, then oak or beech leaves are considered the most suitable. In their natural environment, crayfish eat them every day, which means it is necessary to provide them with the same in the aquarium. In addition to the fact that pets eat this food with pleasure, foliage is also considered an excellent antiseptic. Do not give crayfish such food, they will start to get seriously ill, which should not be allowed.

In addition to the listed foods, there is a small list of things that can be given to crayfish to eat, but these things will greatly worsen the condition of the water. These products include:

• Raw minced meat or meat;
• Bread;
• Cottage cheese.

Breeding crayfish itself is an easy process and not as laborious as it seems at first glance. The most important and prerequisite will be the presence of a large capacity, an aquarium.

And also about which sea fish is the most useful.

In order to stimulate the marriage relationship of a couple and to achieve early offspring from Australian crayfish, they must be planted in different aquariums. After 7 days, the crayfish are returned to their place.

After the appearance of young crustaceans, you need to take care of a separate place of stay for them, in which there will also be many places for shelter. Grown crayfish should be removed immediately. You need to monitor this carefully, as they grow quickly.

Production of elite Australian crayfish that grow to marketable weight in just one year. This information was provided by the commercial director of a small enterprise "Eco-Tropic", which already has experience in growing these delicacies. In 2014, 3 centners of marketable crayfish were sold, at a price of 600 rubles per 1 kg. At the same time, everything was sold out in a few days. “If shrimps are still being delivered to us, then the market is not saturated with crayfish, there is no competition,” Victor shared with us.

The production of such delicacies is profitable, for a one-year cycle, the average weight of cancer is 70-80 grams, and there are 120 grams each. For example, crayfish gain marketable weight of 40 grams in 2-3 years.

Astrakhan "Nadezhda-2" by 2017 will double the production of shrimp and Australian crayfish against the background of a decrease in their imports by 2.5 times compared to 2014 - up to 20 tons per year.“The sales market is huge, no matter how much we produce, we sell everything successfully,” said A. Prelov, General Director of the enterprise.

According to statistics, the total volume of fish production in the world reached 158.3 million tons. Of these, 68 million tons were obtained through commercial fish farming. IN

In Russia, in 2014, fishermen caught 4.2 million tons, and artificial breeding amounted to 160 thousand tons. This is 3.6% of the total. The segment of fish production in Russia lags far behind the global trend. Therefore, Rosrybolovstvo plans to increase the volume of fish farming by 2020 to 315 thousand tons.

Everything looks interesting enough. Huge market, great demand, no competition, industrial breeding of crayfish and fish lags far behind the world market, the business of which has room to grow.

Features of growing Australian cancer at homeBreeding of Australian crayfish is carried out in closed reservoirs and a heated room. For the summer period, the Astrakhan company has applied the technology of growing in a reservoir on the street and quite successfully. The pool must provide access to the surface. Also in the arrangement, cancer requires all kinds of driftwood, stones and sand for minks and shelters. Australian crayfish molt in open space, after which they burrow into a deep cave.

In food they are not whimsical and consume: dead fish, seaweed, mixed feed, bread crumbs, etc. Breeding crayfish fish is possible, but not all. The right option is fast growing cheap fish.

For all types of crayfish, growing in a pond does not bode well for profitability. In the cold period of time, they hibernate and stop growing. In enclosed spaces for Australian, as well as other crayfish, it is necessary to create all conditions.

It is clear that a large crayfish farm is quite expensive to build, but if you grow slowly, having the opportunity to build your own production in the future, investing today in small pools. For a sample, you can buy an aquarium for 100 liters (for 4 crayfish) and today feel free to start your home business for breeding Australian crayfish.

Investing in a crayfish farm. House for breeding crayfish at homeYou will need a room with heating, perhaps a garage or any outbuilding. Then you need a pool, preferably more than one. It requires heating the water in the pool to a certain temperature, as well as a water purification and filtration system. Plus, the living conditions of crayfish should be similar to their native habitat for better growth rates.

Breeding equipment for crayfish

1. Several pools, from 1000 $
2. Aerators, for air supply from $ 500
3. Oxygenator, for young animals from $ 1000
4. Measuring devices for water (oximeter, salt meter, thermometer, conductometer) from $ 500
5. Broodstock (crayfish) for breeding from $ 100 per herd

In total, the approximate investment for growing crayfish at home is from $ 5,000.

Ways to make money on breeding crayfishFeeding option. 200 kg of crayfish (600 pieces) - after a year of fattening - 6000 kg of crayfish.

Breeding option. 500 females per year gives 15,000 crustaceans, which can be sold for further fattening.

Full cycle option. Buy or raise your females, and then fatten crayfish to a presentation.

There is nothing difficult in breeding Australian or other crayfish, the profitability of the business is quite obvious, the relevance for several years in advance, the ability to organize at home in a village or a small city. Obviously, this is a topical home business with minimal investment.

Many lovers of exotic aquarium would like their waters to be inhabited not only by fish, but also by Australian red-clawed crayfish.These are not very large underwater inhabitants, which can surprise with their unusual coloration. But before deciding on such an acquisition, some seek to learn everything about crayfish. Red claw blue cancer has its own characteristics of maintenance and care, they will be discussed in this article.

Habitats in nature

This vibrant underwater dweller is also named Yabbi Red Claw. It can be found in stagnant water bodies in Australia and New Guinea. Since he is a freshwater inhabitant, he settles in ponds, quiet, shallow streams, and sometimes he is found in puddles. Some argue that they noticed this "traveler" in flowing waters, but in fact he chooses only small streams and other similar places with minimal current. With such undemanding qualities of the crayfish, it is suitable for inexperienced aquarists.

External characteristics

The main color of the Australian crayfish is deep blue, and yellowish "freckles" are scattered all over the carapace. The color of the connections between the segments can be not only blue, but also red, orange, pink. However, the saturation of the shades will depend on the hardness of the water in which the Australian crayfish lives. It is best to keep it in hard water for a bright color. If it is soft in composition, the crayfish will turn brown, although the blue tint will remain noticeable.

In nature, they can grow up to 20 cm, and their weight sometimes reaches 500 g. But at home, crayfish do not quite reach this size. Females grow even smaller. In addition, in males, a flat "claw" grows on the outside of the claw, often red, but may be lighter.

Pet character

Despite its large size, the red-clawed Australian crayfish is considered one of the most peaceful. The description of this creature showed that its color is influenced by the hardness of the water. But this circumstance also affects the aggressiveness of cancer. A tougher habitat can make it more hostile.

Despite this, the Australian cancer is capable of peaceful coexistence with fish, and with those who are larger than it, it even lives in the same shelter. But at the same time, they often do not get along with their brothers, and sometimes they engage in cannibalism, eating young animals. Too aggressive individuals can hunt small fish. In addition, if there are too many males in the aquarium, active crayfish will eat their rivals during molting.

These inhabitants can be attributed to nocturnal animals, and they spend the day half asleep. In daylight, they can appear in order to have a snack or if they are about to shed (for this they need free space). But if the cancer did not crawl out for these purposes, perhaps this is a signal that something is wrong in your body of water.

Australian crayfish are creative creatures that can arrange aquarium decorations in their own way. They also use their claws to dig in the silt and make a new hole, which will become their refuge.

Australian red claw crayfish: keeping in the aquarium

This type of crayfish is much easier to care for than its counterparts. In order for your pet to be calm and not nervous, he needs a 200-liter aquarium. It is also worth remembering that one pair requires 150 liters of space. It is better to keep them in hard water, although they can live in softer water.

The aquarium must be decorated with bright things, it can be colorful stones or artificial flowers. They are necessary for carving up territory. In addition, crayfish should have many possible shelters on the territory, otherwise conflicts between brothers will begin. All inhabitants love to have several houses in their possessions at once. It can be minks, driftwood, they are very fond of pipes (ceramic), pots. It should be noted that they are not interested in large stones. They also need sufficient soil to dig their holes.

A desirable condition for the Australian blue crayfish to feel comfortable is to get out of the water. So they have the opportunity to warm up and breathe. But if you have other pets, such as cats, they should not have access to the crawfish that crawled out of the water.

In addition, there should be a space at the bottom where the cancer can freely fade, shedding its old shell. It is worth noting that these pets live for about five years.

Neighborhood in the aquarium

It is advisable to run small fish into the water. Besides diversifying your fauna, there is another reason. After cancer, there is a lot of waste that ends up in the water. Over time, these residues can cause bacterial outbreaks. But, for example, guppy fish or corridors are able to clean them up for crayfish. Such a neighborhood can only bring inconvenience to fish, since they overeat from inability to control themselves. Or they may be scratched by crayfish for stealing their food.

On the other hand, if the guppy dies from overeating, the Australian cancer will become a nurse. So, for the neighborhood, it is better to acquire a medium-sized fish that multiplies quickly. Large fish can eat small crustaceans. You should not breed snails and shrimps in the same aquarium with crayfish.

Vegetation in the aquarium

Australian crayfish love vegetation, so whatever they can get their hands on, they eat. But you can decorate your home pond with plants that stick to the surface. For a constant supply of greens, it is better to have a donor aquarium.

Of all the plants, clidiflora is the longest lasting. The duckweed also spreads quickly, so that the crayfish do not have time to eat it. In addition, on a checked reservoir in the summer, you can stock up on thread. Young crustaceans like to swarm in this plant, gradually eating it. But, when bringing thread from the pond, be careful not to infect the aquarium.

This type of crayfish is not very demanding for the purity of water.

Water temperature

Although the Australian cancer tolerates temperature fluctuations, it is still better not to allow its indicators below 18 ° C: with a prolonged decrease in degrees, the pet may die from hypothermia. The most comfortable temperature will be in the range of 20-26 ° С. If the summer heat comes, the cancer can withstand 30 ° C, but in this case there should be enough oxygen in the water.

Feeding crayfish

Young crayfish are not too picky about food, but at the same time they are inconsistent in their choice of menu. Despite the fact that they are vegetarians by nature, these creatures are not averse to trying a frog, small fish, snails. But the diet for your pet needs to be compiled, taking into account its menu in natural conditions. They usually have oak or beech foliage on a daily basis. This "dish" for Australian crayfish is considered a delicious delicacy. In addition, foliage is a real antiseptic, without which the health and immunity of cancer will decline. If leaves are absent in the diet, your pet will become susceptible to disease.

But besides this, you can dilute your pet's menu with frozen food, peas, earthworms, various vegetables, snails, fish food (with mineral additives and calcium).

It is better if there is a place in the aquarium where you can put fallen leaves, hay, sleeping tea and other plant residues. Although these ingredients are not consumed as quickly, the crayfish will be strong and healthy.

What to feed not worth

Despite the fact that Australian crayfish can eat everything, there are foods that are best not offered to them. Crayfish eat banana peels, grated raw beets, carrots, potatoes poorly. They also spoil the water. Crayfish do not eat apples at all. However, there are foods that are perfectly eaten, but at the same time, they spoil the condition of the water. These include: boiled egg, cottage cheese, bread, raw meat or minced meat. The last two products can be thrown a little at a time.It is rational to give bread if fish coexist in the aquarium.

Sexual characteristics

For Australian red claw breeding to be successful, it is important to learn how to identify males that are ready to breed. This is usually indicated by a flat protrusion on the claw. This is a red build-up (the intensity of the color depends on the hardness of the water). This protrusion does not form from birth, but only after the cancer becomes sexually mature. The moment the male is ready to mate, his protuberance will acquire a more intense tone, which will differ from his usual color.

The female can be identified by her neat claws. Also, the size of the female is slightly inferior to the male.

Breeding crayfish

Just like keeping, breeding and raising Australian crayfish is not as laborious a process as it might seem. An important condition is an aquarium of the required size.

To stimulate the desire for mating games in males and females, it is better to move them from each other to different aquariums for a week. Seven days later, the couple are united, and the "lovers" have several times increased sexual activity.

At the end of mating, the female lays eggs under the abdomen. She bears eggs, and then larvae from 8 to 9 weeks. The length of this period depends on the temperature of the water. At the end of gestation, about a hundred crustaceans appear in the aquarium.

It is necessary to transfer the young growth to other reservoirs. But in order for the offspring to be preserved, many shelters must be provided for the crustaceans in the aquarium. By the way, after the young have been resettled, they need to be closely monitored. They grow fast enough, and you should have time to plant them in size.

These crayfish do not molt at the same time, so there can be both large and small individuals from one female. This is a natural phenomenon, and gradually their size will even out. But until this happens, it is important to settle large and small crustaceans in different aquariums.
