Problems solved by technology

However, although the amount of artificial breeding of loach is expanding year by year, the survival rate of loach is low, especially in summer, if the water quality is not well controlled and the breeding density of loach is too high, a large number of loach will still be suffocated and die

Embodiment 1

[0019] A kind of breeding method of embodiment 1 high survival rate loach, comprises the following steps:

[0020] (1) Choose a site with soft soil, rich humus, sufficient water source, convenient drainage and irrigation, and fresh water quality without pollution;

[0021] (2) Dig out a pond with a depth of 80cm on the selected site, and spread a layer of pebbles on the bottom of the pond. The pebbles are mainly oval, and the whole pond is divided into several small square ponds with cement walls. The area of ​​each small pond 40 square meters, and the small pools are connected to each other;

[0022] (3) A water inlet is provided on the upper part of one of the outermost small pools, and a water outlet is provided at the bottom;

[0023] (4) Set up a gate-shaped passion fruit scaffold across the small pond above each small pond, the height of the scaffold is 1.5, and the distance between adjacent scaffolds is 0.5m;

[0024] (5) half a month before the seedlings are put, the...

Abstract

The invention provides a breeding method of loaches with a high survival rate. The method includes the following steps: 1, choosing a place to construct a pond, and dividing the pond into a number of small pools; 2, forming a water inlet and a water outlet in one small pool; 3, setting up a passion fruit shed frame above the small pools; 4, disinfecting the pond, injecting water in the pond and placing loach fry in the pond; 5, feeding the loaches; 6, conducting disease prevention. The breeding method can effectively inhibit the formation of contaminating microorganisms in the pond and well ensure the subacidity of the water quality, an excellent environment is provided for the loach growth, the loach survival rate is improved, and stems and leaves on the passion fruit shed frame can shield midsummer sunlight for the loach growth so as to avoid the damage of too high temperature to the loaches.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for breeding loach with a high survival rate. Background technique [0002] Loach contains high protein and low fat. The meat is fresh and tender, rich in nutrition, delicious in taste, rich in various vitamins and minerals, and has high nutritional and medicinal value. In recent years, due to overfishing, especially the flooding of electric-caught loach, coupled with the extensive use of pesticides harmful to loach in farmland and changes in farming systems, loach resources in natural waters and paddy fields have declined year by year, and artificially cultured loach has emerged. However, although the artificial culture of loach is expanding year by year, the survival rate of loach is relatively low, especially in summer, if the water quality is not well controlled and the breeding density of loach is too high, a large number of loach will still be suffocated and die.
