A kind of sand pond snakehead factory culture method

Abstract

The invention discloses an Odontobutis obscura factory culture method using a bottom framework and a laying net to realize the bottom isolation technology, thus isolating the Odontobutis obscura living quarter from night soils, effectively ensuring culture water quality, and reducing diseases; the Odontobutis obscura is small in activity scope, enjoys cave inhabitation, and preys in an assault mode; the method uses a baffle to replace the water plant function, thus ensuring the Odontobutis obscura quantity per unit area, so the Odontobutis obscura can more conveniently rest, move and prey; in addition, the bait source is strictly controlled in a culture process, and fresh baits are regularly fed in the whole process, thus ensuring the bait fish quantity per unit area, and preventing Odontobutis obscura from killing each other under food shortage. The Odontobutis obscura factory culture method is a whole new production mode under the best artificially created conditions; compared with a conventional method, the Odontobutis obscura factory culture method is small in land occupation, high in unit yield, short in culture period, thus reducing culture cost, and improving production efficiency.

Description

Technical field [0001] The invention relates to the technical field of fish breeding, and more specifically, to a method for industrialized breeding of sand pond snakehead. Background technique [0002] Because of its tender meat and rich nutrition, the sand pond snakehead is popular with consumers. At present, the wild sand pond snakehead is small and scattered, its living environment is constantly threatened, and the yield in natural waters is getting lower and lower. With the improvement of people's living standards, the market demand for Shatang Channa is increasing, and fishing alone is far from being able to meet market needs. [0003] At present, the breeding of sand pond snakehead is mainly based on nested breeding. Even if the monoculture has a low yield per mu, rarely more than 300 kg / mu, it has caused certain difficulties to the development of sand pond snakehead industry. Therefore, it is a kind of high efficiency and high yield. The breeding mode is imperative. [0004...

With the improvement of people's living standards, the market demand for sand pond snakeheads is increasing, and fishing alone is far from being able to meet market needs

[0003] At present, the culture of sandfish is mainly based on nesting. Even if the yield per mu is very low, rarely more than 300 catties / mu, it has caused certain difficulties to the development of the sandfish industry. Therefore, a high-efficiency and high-yield Farming mode is imperative
