Embodiment 1

[0030] Example 1. A high-density cultivation method for loach, which includes a design and construction method of a loach pond and a high-density cultivation method;

[0031] Loach pond design and construction methods:

[0032] Push pond: the pond area is 1500m 2 , rectangular, with an aspect ratio of 4:1, a base width of 1.8m, a height of 1.0m, and an upper width of 0.7m; the middle bulldozes and builds 5 waterproof dikes around the surroundings, with a water depth of 0.5m; the pond contains 1.5 water bodies (1 The water body is 666.7m 3 );

[0033] Digging trenches: dig trenches around the pond with a depth of 0.25m and a width of 0.15m at a distance of 0.15m from the base of the waterproof embankment 5;

[0034] Lower anti-escape net 2: select net width 1.8m, 40 purpose plastic nets to make anti-escape net 2, the both sides of anti-escape net 2 sew the net outline; The distance between the piles is 1.8m. After the piles are installed, use a horizontal pipe to find a ho...

Abstract

The invention relates to a high-density cultural method of loaches, which is exclusively used for cultivating the loaches and comprises the steps of designing and building ponds, using a high-density cultural technique and designing a water supply and drainage system to perform water quality management. The method can satisfy the biological characteristics of benthonic property, thermophily and shallow water of the loaches, solve the problems that the loaches are good at escaping, are fond of burrowing and are easy to be harmed by natural enemies of mice, snakes and the like, and also solve the problems of water exchange, feedstuff feeding, upper layer algae, oil pollution, discharging of bottom layer impurities and the like. The method has the advantages of high density of the loaches, more increase in yield, low risk, high benefit and wide practicability.

Description

technical field [0001] The invention relates to an aquaculture method, in particular to a high-density loach cultivation method. technical background [0002] Loach (Misgurnusang uillicaudatusontor) is an important export aquatic product in my country, mainly exported to South Korea, and the export volume of Lianyungang City alone accounts for 80% of the South Korean loach market, but our country's loach is mainly exported to South Korea as wild organisms, most of which are seedlings Use, artificially raised in Korea and then put into the Korean market for fresh food and deep processing. [0003] In the early 1980s, my country and South Korea traded with wild loach. With the increase in trade volume, my country has changed from purchasing and exporting to storing and exporting to prolong the export time and solve the shortage of loach in autumn, winter and spring. Storage and export brings higher economic benefits, but also brings greater risks, mainly due to heavy disease a...
