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
[0003] In addition, because the shrimp seedlings raised from July to August will sta

Embodiment 1

[0023] A method for cultivating pollution-free freshwater shrimp, comprising the following steps:

[0024] (1) Requirements for the shrimp pond: the area of ​​the nursery pond is 3 mu, the water depth is 1.0m, the bottom of the pond is flat, and the silt removal is not more than 10 cm;

[0025] (2) Shrimp pond treatment: Use quicklime in the freshwater shrimp pond, inject 20cm of clear water, disinfect and improve the bottom, drain it after 24 hours, and then enter the filtered water for 30cm after disinfection in the pond, and apply special biological fertilizer for aquaculture and containing Bacillus Beneficial biological fertilizer preparations for cultivating water quality;

[0026] (3) Crossbreeding: use young Taihu Lake female shrimp and local male shrimp to hybridize at 2:1 (female shrimp and local male shrimp are fished and screened with conventional equipment);

[0027] (4) Stocking of shrimp seedlings: 60,000 shrimp seedlings per mu are stocked from late July to ear...

Embodiment 2

[0032] The conditions are basically the same as in Example 1. A method for cultivating pollution-free freshwater shrimp, comprising the following steps: the area of ​​the nursery pond is preferably 5 mu, the water depth is 1.2m, the bottom of the pond is flat, and the mud is removed no more than 10 cm; the freshwater shrimp pond is filled with bleaching powder, injected with 30cm of clear water, and disinfected for 24 hours After being drained and sterilized, it will be filtered into 40cm of water, and special bio-fertilizer for aquaculture and beneficial bio-fertilizer preparations containing bacillus will be applied to cultivate water quality. , from late July to early August, stock 60,000 shrimp seedlings per mu; on the 14th day in the early stage, feed a combination of plant feed and animal feed at a ratio of 7:3, mix it with water and put it in the pond. Sprinkle around, feed about 1 mg per mu; after the shrimp grows to 2cm, you can feed pellet feed, the amount of feeding...

Embodiment 3

[0034] The conditions are basically the same as in Example 1. A method for cultivating pollution-free freshwater shrimp, comprising the following steps: the area of ​​the nursery pond is preferably 4 mu, the water depth is 1.1m, the bottom of the pond is flat, and the mud is removed no more than 10 centimeters; the freshwater shrimp pond is filled with bleaching powder, injected with 25cm of clear water, and disinfected , drained after 24 hours, after disinfection, then enter the filtered water 35cm, and apply special bio-fertilizer for aquaculture and beneficial bio-fertilizer preparations containing bacillus to cultivate water quality; in Taihu Lake young female shrimp and local male shrimp 2:1 After hybridization, stock 60,000 shrimp seedlings per mu from late July to early August; on the 13th day in the early stage, feed a combination of plant feed and animal feed at a ratio of 7:3, and mix well with water. Sprinkle around the pond, feed about 1 mg per mu; after the shrimp...

Abstract

The invention relates to a freshwater shrimp cultivation method, in particular to a pollution-free freshwater shrimp cultivation method according to which hybridization is adopted and fish larvae are matched for cultivation together. The pollution-free freshwater shrimp cultivation method includes the following steps of shrimp pond requirements, shrimp pond treatment, hybridization, shrimp larvae breeding, feeing management, water quality management and density control. The pollution-free freshwater shrimp cultivation method makes the most of idle resources for production, standardizes cultivation techniques, and obtains high-quality offspring seeds for cultivation after Lake Taihu youth shimps and local shrimps are hybridized; moreover, when a second generation of freshwater shrimps are reproduced, the fish larvae are bred, on the one hand, small shrimp larvae can be used as feed of the fish larvae, and on the other hand, space is saved by the small shrimp larvae which are eaten and oxygen consumption is reduced, and therefore unified specifications and high output of the freshwater shrimps are ensured.

Description

technical field [0001] The invention relates to a method for cultivating freshwater shrimp, in particular to a method for cultivating pollution-free freshwater shrimp by hybridizing and cultivating fish fry together. Background technique [0002] Freshwater freshwater freshwater prawn, scientific name Macrobrachium nipponense, belongs to crustaceans, decapods, swimming suborders, true shrimp pie, long arm family, macrobrachium genus, a kind of freshwater prawns with a large number, and my country's freshwater aquaculture industry One of the traditional economic shrimp species in China. 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 shrim...
