How to raise crayfish at home, crayfish is a lot of people in our lives like to eat a kind of food, we all know that a lot of animals are in a certain condition in order to breed, for crayfish many people have tried to raise, the following how to raise crayfish at home.

How to raise your own crayfish at home 1

Family to raise crayfish as an ornamental, pay attention to the following:

1, containers

Keeping crayfish, you can use plastic pots, organizing boxes, acrylic or glass aquariums and so on. Note that the height of the container should not be lower than the length of the body of the crayfish to prevent their escape.

2, the environment

With a filtration system, can be arranged to simulate the natural environment, placing roots, bamboo tubes, etc. for its climbing, planting Anemone, Rotifera and other plants for its hiding, sheltering, feeding, the water depth of up to 0.5 meters. If there is no filtration system, it is recommended to keep it in a bare tank with a few plants. The water depth should be 3~5 centimeters. When the water quality deteriorates, change the water in time.

3, the number

Crayfish stocking density is too easy to cause oxygen deprivation, fighting and other phenomena such as disability, home rearing so adult crayfish, up to one per square decimeter. At the same time, too many males are also prone to cause fighting, so the ratio of male to female is 3:1 the best.

4, feeding

Crayfish are omnivorous, both like to eat fresh fish and other animal bait, but also like to eat soybeans, bean cakes, corn, fruit and fresh water plants and other plant bait, home rearing can be fed to the fish, snails, shrimp, watermelon, steamed bread and so on. In the case of quality assurance, the general amount of bait per day should be mastered in order to eat, eat, do not leave residual bait shall prevail, July ~ October water temperature is suitable, is the growing season of shrimp, feeding 2 times a day, morning and evening 1 time.

The rest of the season feeding once a day. Because crayfish mainly feed at night, so the night feeding accounted for 70% to 80% of the whole day's bait. When the weather is good, more cast, high temperature and sultry, continuous rainy days or water quality is too thick to cast less; a large number of shrimp molt less cast, more cast after the molt.

Note: The body of the newly molted shrimp is very soft, and should be kept separately to prevent it from being used as food by other shrimp.

Crayfish aquaculture technology

First, to create a good environment for lobster growth. Lobster is a crustacean, similar to the crab, there is a pair of particularly developed chelipeds, have dug holes *** habit of living, generally near the water's edge to dig ****. Lobster like shade and fear of light, weak light or darkness when climbing out of the hole ****, strong light, then sink into the water or hide in the hole ****. According to the habits of the lobster, can be added to the river pond 50 cm high anti-escape net, to prevent the lobster from escaping.

At the same time, the river pond simulates the ecological environment of the lobster under natural conditions, shallow planting of 10-15% of the pool side of the water plants, hidden objects, to create an environment for lobster habitat and shelling, to reduce mutual slaughter.

The impact of water quality on lobster production can not be ignored. Good or bad water quality directly affects the healthy growth and development of lobsters, breeding process, the pool water ph value to maintain between 7.5-8.5, transparency of 30-40 centimeters, should be frequently refilled with new water, regularly sprinkled with quicklime solution to regulate the water quality, to prevent the occurrence of disease and shelling attempts.

Second, reasonable feeding feed. Lobster in the case of hunger and insufficient food, will kill each other, so the amount of feeding must be sufficient. Lobster feed is plant and animal feed. Plant feed for wheat, watercress, rapeseed cake, etc., animal feed for miscellaneous fish, miscellaneous meat and animal offal. Usually according to the habits of lobster day and night and the density of shrimp in the pool to determine the feeding time, feeding volume and feeding methods. Otherwise, it will increase the feed plus cost, reduce the benefits of aquaculture.

Third, scientific fishing. In the lobster aquaculture process, young shrimp at a suitable temperature, adequate feed 'case, generally 60-90 days to grow to commercial specifications. March release seedlings, around June began to rotate the catch, sell the big to stay small. As a result of the capture of the big to stay small, round catch and release, can improve the rate of capture, sold at a good price, to achieve the purpose of high-yield and efficient.

Crayfish good breeding

Environment: Crayfish often live in streams or marshes and other diving environments, or sloping dams, because of its need to expose the water surface from time to time to breathe, especially in summer when dissolved oxygen in the water is easy to hypoxia, so China's rice paddies, ponds, rivers are very suitable for Crayfish farming, if farming in rice paddies, pay attention not to use chemical fertilizers and pesticides,

Crayfish do not like sewage as rumors, it prefers a clean environment, just because of the more varied nature of the food has been rumored to be like that, breeding crayfish to preserve the value of the water quality, and to provide some aquatic grasses for its habitat.

Feeds: crayfish food is very miscellaneous, water plants, bugs, and even animal carcasses it will eat, which is why some people feel that the crayfish "dirty", but the breeding of crayfish is based on synthetic feeds, crayfish are mainly in the night feeding, generally feeding twice a day, once in the evening, once in the evening, crayfish, crayfish, crayfish, crayfish, crayfish, crayfish, crayfish, crayfish, crayfish, crayfish, crayfish, crayfish, crayfish, crayfish, crayfish, and crayfish. For calcium has a high demand, if there are conditions, you can feed some snails, clams for its calcium supplement, or regular splashing quicklime, can play a disease prevention effect can also increase the calcium in the water.

Escape: crayfish can play holes, can go ashore, so the breeding of crayfish must do a good job to prevent escape measures, otherwise it may be a basket of water is empty, generally use the escape net to prevent their escape.

Fishing: Crayfish fishing is not a one-time fish all, but fish while raising, pay attention to observe the size of the crayfish, there are a large number of individuals available on the market will begin to selective fishing, will be a large fish up for sale, smaller put back, after fishing crayfish density decline, these put back the shrimp growth rate will be faster, crayfish can be almost year-round reproduction, and found that the shrimp holding the eggs to be put back.

How to raise crayfish at home yourself 3

Three ways to raise crayfish, crayfish farming in January will not die.

First: for those who like to eat crayfish, although it is said that the crayfish in the pot made of spicy lobster, looking very cruel, but eat very tasty, and even some people buy back the crayfish like to slowly savor. Eat so many a day, but the breeding time is long the lobster naturally die. Some people want to keep the crayfish three days of survival time, this is very simple, first we will pour the crayfish inside the water basin, a few drops of cooking oil in the water basin, and then add some salt,

With such a method can ensure that the crayfish survive for a week of time, it may be asked fresh crayfish, the need to add cooking oil and salt in the lye water is the reason for it? Suppose the reason for the edible salt is that it can make the crayfish will be inside the body of bacteria and dust has often spit out. Simple and effective, ensuring the survival of crayfish.

Method 2: the second continuation of the crayfish family survival method, is that we will buy back the crayfish, the rest of the spread in a cool place, let's say in the corner or in the basement, etc., and then sprinkled a little water on the ground.

This time we pay attention not to submerge the crayfish overall body, which may lead to the crayfish will be hypoxic, just like people, a large number of hypoxia naturally lead to the death of the crayfish, while reminding us not to put the crayfish in direct sunlight, just keep the body of the crayfish to have a degree of wetness can be. If we breed crayfish is not too much, with this method is very simple, and very practical.

Method 3: The 3rd method of extending the life of the crayfish is that, after our family crayfish purchased back, the crayfish small brother left, because we may also be able to find the claws of the crayfish is very sharp, the crayfish fighting is also very strong, if we collectively put the lobster on the plate, then the crayfish will fight each other.

This time we can put the crayfish in a damp place, and then use a black plastic bag to cover the crayfish, the lobster is in a dormant time, then it will not fight to escape. Or that we use some rope or fabric, to tie the claws of the crayfish. Crayfish body without trauma, then the lobster vitality is also more vigorous.
