Shrimp breeding and raising integrated method

Abstract

The invention provides a shrimp breeding and raising integrated method, which comprises the steps of erect a net cage that has suitable size and mesh specification in a shrimp raising pool; raising shrimp with eggs of a certain phase temporarily in the net cage; and breeding the young shrimp in the pool. <{EN2}>The young shrimp raising regularity and specification are effectively guaranteed by controlling the birth time of the shrimp with eggs artificially; at the same time, the young shrimp and the adult shrimp are raised in the same pool by taking measures like reasonable feeding management, water quality regulation and control, and daily management. In this way, the shrimp is breed and raised together; raising cost is reduced; labor intensity is lowered; the proportion of large shrimps is lifted; and the shrimp raising benefit is raised. <{EN3}>The advantages of the present invention are that the specification of the raised young shrimp is generally the same; the proportion of the raised large shrimps is higher than the proportion in traditional raising way; labor force cost for raising the shrimp is reduced because the shrimp is breed and raised in the same pool; the parent shrimp used for breeding can be captured and recovered, and the raising cost is reduced because the recovery rate is high.

Description

technical field [0001] The technical proposal belongs to the technical field of aquaculture, and specifically relates to an integrated culture method for breeding freshwater shrimp. Background technique [0002] In the prior art, many aquatic products are cultivated in an independent environment first, and then the seedlings are sent to another independent environment for cultivation. The two environments do not interfere with each other, and the breeding and breeding methods are independent of each other and do not affect each other. For example, freshwater prawns, the general view of farmers is that if they put in brood broodstock, they will breed in the pond and grow directly. Although it is simple and easy, the yield is low and unstable. The main reason is that the survival rate of larvae is low and often multiple generations Ponds cannot control the density, and the management is very blind. The result specifications are uneven, the overall size is small, and the listi...

AI Technical Summary

Problems solved by technology

However, during the entire breeding process, it is necessary to turn the pond from the nursery pond to the breeding pond. The main problems are: increased labor costs for freshwater shrimp cultivation; The recovery rate of post-spawn shrimp is low, which indirectly increases the cost of breeding; due to the use of special ponds for the breeding and cultivation of shrimp seedlings, the number of ponds required is large, which virtually increases the cost of ponds

In addition, during the breeding process of shrimp seedlings, due to the difficulty in timely determining the situation of egg-bearing shrimp loose seeds, it is usually estimated based on farming experience, which increases the uncertainty of shrimp seedling breeding. At the same time, affected by the low recovery rate of egg-bearing shrimp, some scattered seeds The eggs-embracing shrimps that are late are still loose seeds in the pond, which reduces the uniformity of shrimp seedling cultivation, thus affecting the size and output of adult shrimp farming
