How to breed crayfish 1, site construction
First of all, it is necessary to build a good site for crayfish breeding. Generally, the shrimp ponds for crayfish breeding are rebuilt by using old rice fields. It is necessary to raise the surrounding dams and clean up the mud and debris at the bottom of the ponds. Fine nets are added on all sides to prevent crayfish from escaping, and short fences are enclosed. Fine nets are installed at the entrance and exit to protect the shrimp ponds.
2, shrimp seed delivery
Before the shrimp seeds are put in, a certain amount of fertilizer should be poured into the shrimp pond, and some plants such as algae can be planted after the water in the pond becomes yellow, green and clear. After the zooplankton in the pond gradually proliferates and grows, the shrimp seeds should be put in sunny and cool days, and about 40 kilograms of shrimp seeds can be put in one acre.
3. Feed feeding
Feeding feed is also very important. Crayfish is too small in childhood, and can only feed on the detritus leaves of plankton and algae. When it grows up, it can prey on benthic aquatic animals independently. When feeding it with high-protein food, animal viscera can also be used, but attention should be paid to fixed-point quantification at regular intervals.
4, regular inspections
Be sure to patrol the crayfish pond regularly, especially when it rains, when the water level rises, lobsters are likely to escape. We should reinforce fences and iron nets in time to prevent losses, and adjust the water quality regularly to replace fresh water according to the situation of shrimp groups, so as to salvage food residues and debris in the pond in time.
