Culture techniques of indoor crayfish

Indoor crayfish culture is currently a relatively modern culture technology, in terms of the current situation, the prospect of this industry is still very good, so how to cultivate crayfish indoors? What is the breeding technique of indoor crayfish? Let's take a look at it with the editor.

I. Construction of breeding farms

Generally speaking, the construction of cement ponds is used when raising crayfish indoors, but during the construction, we need to pay attention to the area of crayfish pool, the density of crayfish and the indoor environment to build. And when building culture ponds, they are divided into breeding ponds, incubation ponds and cultivation ponds, and give them separate breeding and communication facilities at different stages, so as to provide crayfish with a good living environment. It's good for their growth.

II. Selection and stocking of shrimp fry

The choice of shrimp fry is also more important, because indoor culture in all aspects of factors are not external conditions of high quality, so the requirements of shrimp fry are more stringent. Generally choose shiny color, smooth body surface without attachments, body surface intact without injury, strong physique without disease, more dynamic shrimp seedlings, so that the survival rate of shrimp seedlings will be higher. Before the shrimp seedlings are released, the shrimp seedlings need to be sterilized and then put into the culture pond to avoid bacterial infection.

III. Feed and feeding

Crayfish feeding and feeding is also a very important link. In general, crayfish are fed with mixed fish and snail meat mixed with some plants. When feeding, we should pay attention to the number of times and dosage should not be too much nor too little, too little will cause crayfish to kill each other, and too much will not only waste feed, but also easily lead to crayfish to die. Under normal circumstances, you need to feed about three times a day. If the weather is bad, crayfish will lose their appetite. Generally, they can be fed once.
