What can crayfish eat to increase production? In recent years, the crayfish aquaculture industry in various parts of the country has been extremely hot. The supply of artificially cultured lobsters is in short supply. However, there are not many farmers who can really produce the lobsters. How to achieve high quality and high yields has become the most important issue for farm research.
Farmers need to plant aquatic plants such as water hyacinths, water peanuts, water lettuces, and white pebbles around the pool. Their coverage is generally 1/3 of the surface of the pond, in order to facilitate crayfish shade and plankton-eating plankton. The stocking specifications must not differ too much, and the stocking specifications should be basically the same. When crayfish are stocked, attention should be paid to the specifications of crayfish, which are stocked in three sizes: large, medium and small. If the stocking size is different, there will be the phenomenon of prawns eating shrimp, so that the survival rate is greatly reduced, affecting the increase of aquaculture production.
It is not enough for crayfish to eat only plankton, and the feeding baits and their standards are also very important. Within 3 days after seedling, minced small fish and minced meat were added. Within 3 days, small trash fish, minced meat or compound feed was put in within 1 month. When the shrimp was 6 to 7 centimeters in length, they could all be fed. Crushed snails, river clams and appropriate amounts of vegetable feed such as wheat, bran, corn, cakes, and compound feeds. The amount of daily feeding should be sufficient to eat, eat, and leave no residual baits, which can be adjusted according to the eating conditions of the shrimp. Feed 2 times a day, once in the morning and in the evening, and feed at 70%-80% of the daily feed at night. The bait should be thrown in places where the crayfish are concentrated to invest more to facilitate their feeding.
