Problems solved by technology

At present, relying on natural resources alone is far from being able to meet the market demand, and artificial breeding is imperative. However, the problem of seedlings must first be solved for artificial breeding. Among them, the seedling cultivation technology of wheat ear carp is still far from perfect. There are many problems in the selection and feeding of bait, the synchronization of larvae development and disease control, etc., and it is difficult to realize the mass production of large-scale and healthy fingerlings. develop

Embodiment Construction

[0016] A concentrated aerobic cultivation method for wheat ear carp fry, comprising the following steps:

[0017] (1) Seed source

[0018] The wheat ear carp seed comes from the same batch of seedlings artificially propagated by Jing County Daling Seed Co., Ltd., Xuancheng;

[0019] (2) Treatment of cultivation ponds

[0020] The method of pond cultivation is adopted, and the pond area is 1500m 2 On the right, there are 2 ponds in total; in the cultivation ponds, 60kg of disinfectant should be applied one week before the seedlings are released to clear the ponds and sun-dry the ponds, and then fill them with water. The water depth is 0.5m. Sprinkle the whole pond, put the manure into the woven bag and soak in the water, add water to 0.7m on the 5th day, cultivate rotifers and other fry opening bait organisms, and release the fry after the bait organisms in the pool water reach the peak and the water quality is stable;

[0021] (3) Concentrated aerobic cultivation method

Abstract

The invention discloses a concentrated aeration breeding method of pseudorasbora parva fries. The method includes the steps of fry origin, breeding pond treatment, concentrated aeration breeding and the like. According to the concentrated aeration breeding method, feeding can be performed in a concentrated mode without worrying the situation that environmental deterioration occurs due to little water, the fries cannot swim freely when just being placed in the pond, when the fries grow up gradually and can forge freely, the fries can swim away freely, the living space is large, competition between individuals is reduced, the growth rate is very high, the survival rate is high, the pond breeding efficiency is high, management and popularization are easy, and huge economic benefits exist.

Description

technical field [0001] The invention relates to a concentrated oxygen-increasing cultivation method for seedlings of oyster carp, belonging to the technical field of aquaculture. Background technique [0002] Wheat ear fish (Pseudoroasbora parva) is a common fish, often distributed in fresh water, previously considered as wild fish, was cleared ponds. Now because of its delicious taste, high nutritional value, and less thorns, it is deeply loved by consumers, and the price is also rising, from the initial 10 yuan / kg to the current 28 yuan / kg. At present, relying on natural resources alone is far from being able to meet the market demand, and artificial breeding is imperative. However, the problem of seedlings must first be solved for artificial breeding. Among them, the seedling cultivation technology of wheat ear carp is still far from perfect. There are many problems in the selection and feeding of bait, the synchronization of larvae development and disease control, etc.,...
