Problems solved by technology
Now more and more farmers are starting to cultivate crayfish artificially, but due to the immature artificial propagation technology, the seedlings cultivated are unstable and the yield is low, making the supply of seedlings in short supply, and it is impossible to realize large-scale cultivation of crayfish , affecting the development of crawfish industry

Embodiment Construction
[0025] A high-quality and high-yield breeding method for crayfish fry, comprising the following steps:
[0026] (1) Broodstock selection
[0027] Broodstock requires complete appendages, lively and strong, bright and shiny body color, strong physique, well-developed gonads, weight 35-50g, body length 7-8.5cm;
[0028] (2) Intensive breeding of broodstock
[0029] Put the broodstock shrimp into the cultivation pool covered with sunshade cloth for a period of intensive cultivation for one month. During the cultivation period, disinfect the cultivation pond twice with disinfectant on a regular basis. Feed 3% of the meat feed, flush the broodstock once a day at 19:00, change the water every 5 days, and change the water every time to 1 / 2 of the water depth of the pond. After the broodstock is stable, the ratio of male to female is 2:1. Put it into the breeding pool and strengthen daily management;
[0030] (3) Daily management
[0031] ①Water quality management

The invention discloses a high-quality and high-yield breeding method for procambarus clarkii seeds. The method comprises the steps of parent shrimp selection, parent shrimp fortified-breeding, daily management and the like. According to the method, measures such as water temperature management, water quality regulation, feed fortification and ecological environment improvement are taken, so that the synchronous development of gonads of procambarus clarkia is promoted, the synchronous spawning of the procambarus clarkia is induced, and the aims of large-scale breeding and improvement of the seed yield are fulfilled; by reasonable high-quality population preservation and allopatric male and female proportioning, excellent characters of the bred procambarus clarkia are optimized, and a technology suitable for the regional standard breeding of high-quality procambarus clarkia seeds is implemented; the annual yield of 5 acres of procambarus clarkia seed breeding base can reach more than 1,500,000 juvenile prawns in 1-2 cm, and the juvenile prawns can meet the requirements of 100-acre pond breeding.
Description
technical field [0001] The invention relates to a high-quality and high-yield breeding method for crayfish seedlings, belonging to the technical field of aquaculture. Background technique [0002] Crayfish, also known as crayfish, is the most widely distributed and most commonly farmed freshwater crayfish in the world. The shrimp meat is delicious, unique in flavor, rich in nutrition, high in protein, low in fat, rich in calcium, phosphorus, iron, etc. It has become a delicious food on the table of urban and rural residents, and is increasingly favored by domestic and foreign markets. One of the main aquatic products that earn foreign exchange. The discovery of the value of crayfish has induced people to fish in large quantities, resulting in the depletion of wild crayfish resources. Now more and more farmers are starting to cultivate crayfish artificially, but due to the immature artificial propagation technology, the seedlings cultivated are unstable and the yield is low...
