Does the hatching of the crayfish need to be heated, and the correct feeding method of the crayfish

The hatching of crayfish does not need to be heated, and it should be noted that the water temperature of crayfish breeding should be around 24 to 26 degrees, which is conducive to the hatching of fertilized eggs.

Crayfish grow to 3 months when it is the age of crayfish breeding, at this time we must ensure that the space in the tank is large enough, water quality, temperature, etc. are in the best state, after successful mating, you can add some high-protein food appropriately, and so on for a period of time you will find that the female shrimp is hiding, and even plug the hole, at this time is the shrimp successfully hold the eggs, at this time do not alarm it, otherwise it is easy to kick the eggs, if there are conditions, it is best to isolate it.

After the mother shrimp holds the eggs, it must be ensured that there is enough moss in the tank, which is to block the light, but also to provide sufficient food for the mother shrimp, and the small shrimp will be attached to the moss after the next body. Usually after the eggs, you can slowly raise the water temperature by 1 to 2 degrees, but the temperature should not be too high otherwise it will cause hypoxic necrosis, depending on the species, the egg holding time is possible from 3 weeks to 6 months, just wait slowly.

In addition, it should be noted that the water temperature of crayfish breeding should be about 24 to 26 degrees, which is conducive to the hatching of fertilized eggs, and the hatching time will break through the membrane and become larvae in about 14 days, but if the water temperature is too low, the hatching time will be delayed, and the larvae that have just hatched are 5-6mm long, relying on yolk nutrition, and molting and developing into a second stage larvae after a few days. The shape of the larvae in the second stage is similar to that of adult shrimp.

Do you use an incubator?

Keeping the water temperature at 24 degrees is fine.

When it grows to 3 months, it is the age of crayfish reproduction, and it breeds once or twice a year, at this time, it is necessary to ensure that the space in the tank is large enough, the water quality, temperature, etc. are in the best state, and after successful mating, some high-protein food can be added appropriately;

After a period of time, you will find that the female shrimp is hiding, and even plugging the hole, at this time the shrimp has successfully held the eggs, at this time do not alarm it, otherwise it is easy to kick the eggs, if there is a condition, it is best to isolate it.

After the mother shrimp holds the eggs, it must ensure that there is enough mosse in the tank, which is to block the light, but also to provide sufficient food for the mother shrimp, after holding the eggs, the water temperature can be slowly raised by 1 to 2 degrees, but the temperature should not be too high, otherwise it will cause hypoxia necrosis.

1. When the body length of the crayfish is more than 8cm, the feeding time is more than half a year, and the tail can be mated.

Put the male crayfish into the female crayfish breeding tank, observe whether the female shrimp let the tail mate, from familiarity to action is also very fast, if there is no mating during the day, to be safe, separate them before you go to sleep, and close the tank again the next day. Normally, if a pair of shrimp mates, they will not attack each other very affectionately. It should be noted that if there are signs of shelling of shrimp during the closing of the tank, then the tank must be divided, and when the shrimp is shelled for 5-7 days, the shell is calcified and hard, and the tank is closed again.

2. The seminal vesicles are full several times, and the female shrimp does not let the male shrimp mate, and there is not much to eat, so you can take the male shrimp out at this time and give the female shrimp a quiet environment to wait for the eggs.

3. After a period of cycle, the female shrimp basically does not eat, and is turning the bottom sand, creating a sand pit or hiding in the jar and not coming out, and she is about to hold the egg.

4. During the period when the female shrimp holds eggs, there is no need to feed animal feed, and some aquatic plants are put in the tank, and it will occasionally eat some. Precautions: Be sure not to frighten it, let alone use a net to catch it, so it will basically kick the eggs.

Try not to change the water during the egg holding, and add water with a slow flow of water to avoid obvious changes in pH and temperature differences.

5. The egg-holding cycle is 25-28 days, the juvenile shrimp has been formed, and gradually will walk around the female shrimp's abdomen, but it is basically around the female shrimp.

6. After the female shrimp is shaken, she has to shed her shell several times before she can enter the next mating and reproduction cycle.

Crayfish are not only nutritious but also highly effective, and the aquarium is the most suitable for ornamental crayfish feeders for easy viewing glass or acrylic transparent aquariums. If you need to raise more, you should prepare more aquariums, because it has the habit of eating the same kind, you can't mix more than one, and you can only raise 1 2 per feeder. If you only raise 1 2 crayfish, use a rectangular aquarium of 30 cm * 25 cm.

The bottom of the box can be filled with 3 7 cm thick sand, and pebbles of different sizes and colors can be placed for decoration. The box can be filled with water up to 14 to 16 cm deep. If it is difficult to get this water in the city and need to replace it with tap water, you can put the tap water in a basin or bucket for 2 or 3 days before use.

Put some algae plants or other green aquatic plants in the water as a shelter for crayfish. The top of the aquarium should be covered with a lid made of barbed wire, and it is best to press two heavy iron bars on it to prevent dogs, cats, rats, etc. from coming to prevent them.

Feeding food, to always pay attention to the water quality, generally cool spring and autumn 3 5 days to change the water 1 time, winter cold weather 7 10 days to change the water once, summer hot 1 2 days should be changed water. If there is any leftover residue and debris in the food that is usually fed, it should be removed immediately with a gauze cover to avoid polluting the water quality.

1. Pay attention to density.

Before making and raising crayfish, we must first choose a good shrimp tank, and plan the density of rearing, and whether to polyculture other ornamental shrimp. Crayfish is a more aggressive ornamental shrimp, crayfish has a strong sense of territory, if you don't want to raise your own crayfish often fight and get injured, it is best to reduce the breeding density.

2. Landscaping in the cylinder.

Establishing a good ecological environment is a very important point for raising crayfish, crayfish like to live on sand and gravel, so the bottom sand should be laid in the shrimp tank, and the bottom can be paved with an appropriate amount of maifan stone, coral sand and other materials. It is also necessary to put in sunken wood, stones, aquatic plants, etc., to provide a place for crayfish to hide and feed. It should also be paired with aquatic plants to enhance their absorption of trace elements.

3. Reasonable feeding.

The food that can be eaten by the shrimp is bloodworm, vegetables, harvest shrimp, etc., the bloodworm is highly nutritious, and it can be regarded as the main food of the shrimp, so that the shrimp can grow faster and more robust. Celery stalks are generally recommended for vegetables, and spinach leaves can also be fed, but they are easy to pollute water quality and are not easy to clean.

4. Regular maintenance.

It is very important to change the water regularly and clean the filtration system, we must pay attention to the water quality when raising crayfish, and regularly clean up the residual food in the shrimp tank.
