Mud fish fry breeding method

Abstract

The invention discloses a mud fish fry breeding method. The method comprises the following steps of (1) injecting non-polluting water into a soilless breeding pond in a greenhouse, and putting in weeping willow branches; (2) 20-30 days after putting in the weeping willow branches, putting in mud fish fry and placing ricefield eels the next day. The method has the advantages of convenient materialobtaining, easy water quality regulation, convenient fishing, less mud fish pests and diseases, high fry survival rate and the like.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for cultivating loach fry. Background technique [0002] The artificial breeding of loach (Misgurnus anguillicaudatus) has a large space for development. At present, the parental selection, induced labor, fertilization, hatching and other technologies of loach are very mature, and many breeding farms are able to produce and provide loach splashes (body length less than 1cm) in large quantities. However, because loach seedlings with a body length of 1-3cm are in a transitional sensitive period from gill respiration to intestinal respiration, they are demanding on environmental conditions, such as parent quality, hatching method, aeration method, open bait, breeding density, water quality, pests and diseases, etc. There are too many influencing factors, such as aquatic plants and aquatic plants species, which are difficult to control systematically. The pr...

Problems solved by technology

However, because loach seedlings with a body length of 1-3cm are in a transitional sensitive period from gill respiration to intestinal respiration, they are demanding on environmental conditions, such as parent quality, hatching method, aeration method, open bait, breeding density, water quality, pests and diseases, etc. There are too many influencing factors, such as aquatic plants and aquatic plants species, which are difficult to control systematically. The problem of "death in small pieces" is very prominent. The dead loach seedlings seriously pollute the aquaculture water body, resulting in extremely low survival rate of loach seedlings, and the mortality rate is as high as 50%-80%. 100% (Xiaxia Zhang, Causes and Solutions of "Inch Slice Death" in Loach Nursery, Scientific Research Aquatic Fishery, 2016 Issue 7 (Second Half Month))
