Problems solved by technology

Due to the fact that there are many diseases, high cost, and heavy pollution in the cultivation of freshwater shrimp, the enthusiasm for breeding freshwater shrimp is not high, resulting in a large number of ponds being semi-deserted or empty; moreover, in artificial breeding, the size of freshwater shrimp is small and the feed coefficient is large, which leads to inbreeding of freshwater shrimp. Problems such as vicious circle and non-standard farming techniques have not been resolved
In addition, because the shrimp seedlings raised from July to August will start to

Embodiment 1

[0018] A method for high-yield breeding of green shrimp includes the following steps:

[0019] (1) The specifications of the nursery pond are: the area of ​​the shrimp pond is 3 mu, the water depth of the shrimp pond is 1.2m, the bottom of the pond is flat, and the silt at the bottom of the shrimp pond is removed so that the thickness of the silt is not more than 8cm;

[0020] (2) Then the shrimp pond is disinfected with quicklime, bleaching powder, ammonia water or bleaching powder essence, and 25 cm of clean water is injected to improve the bottom quality. After 24 hours, it is drained. After disinfection in the tank, it is injected with filtered water of 30-50 mesh yarn. 40cm, and put natural fertilizer composed of animal feces and beneficial biological fertilizer preparations containing Bacillus into the shrimp ponds to cultivate water quality;

[0021] (3) Hybridize young female shrimp and male shrimp at a mass ratio of 2:1 to produce seedlings;

[0022] (4) Shrimp larvae are sto...

Abstract

The invention provides a mixed culture method for fishes and macrobrachium nipponense. The method comprises the following steps: firstly disinfecting a macrobrachium nipponense pond, cultivating macrobrachium nipponense larvae through mating of male and female macrobrachium nipponense, throwing the macrobrachium nipponense larvae from the middle ten days of the July to the middle ten days of the August, throwing fry from the September to the October, and performing feeding and culture. According to the invention, the method takes full advantage of idle production resources, does not need to increase professional equipment, has no culture pollution, employs industrialized management personnel and normative culture technical standards, applies a biological agent to control water quality, reduces the use amount of drugs, makes the macrobrachium nipponense meet pollution-free and healthy requirements, and improves product quality value. In addition, the high-quality macrobrachium nipponense larvae obtained after hybridization can exert heterosis, and has obvious improvement in aspects such as improvement of a growth speed and disease and stress resistant ability and delaying of sexualmaturity than macrobrachium nipponense larvae obtained by cultivation of traditional local macrobrachium nipponense parents.

Description

Technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a fish and shrimp mixed culture method. Background technique [0002] Freshwater green prawn, scientific name Macrobrachium nipponense, belongs to crustaceans, decapod, natator suborder, prawn pie, longbrachidae, macrobrachium genus, a large number of freshwater prawns, freshwater aquaculture in my country One of the traditional economic shrimp species in China. Due to the large number of diseases, high costs, and high pollution in the current culture of blue prawns, the enthusiasm for breeding blue prawns is not high, resulting in a large number of ponds semi-barren or idle; in addition, the small size of blue prawns and large feed coefficients in artificial breeding have led to inbreeding of blue prawns. The vicious circle, non-standard breeding technology and other issues cannot be solved. In addition, the shrimp larvae raised from July to August will start to repr...
