Problems solved by technology

[0003] The number of wild snakeheads is small and scattered. In addition, the individuals are small and the natural output is not high, which cannot meet the market demand.
It takes a long time for the breeding and hatching of sandfish, and it takes 15-21 days to hatch seedlings. Large-scale seedlings are restricted, let alone artificial breeding in ponds.

Embodiment 1

[0023] (1) The pond is 2.5 mu, and the water depth is 1.5 meters. Branches, tiles, tiles, etc. are laid on the bottom of the pond as shelters for habitat, and the sand pond snakehead is mainly raised. On June 6, 2011, 10,000 large-scale summer flowers of 3.5-4.5 centimeters in length were stocked.

[0024] (2) The water transparency of the sand pond snakehead fish pond is 30cm-40cm.

[0025] (3) Match with 30 catties of river prawns, 50 fish species of flower and silver carp.

[0026] (4) Feed

[0027] The protein content of the feed is 40% and the crude fat is 6.0%. It is produced by a feed company in Jiangsu.

[0028] (5) Feed coefficient

[0029] Using the feed with 40% protein content to breed sand pond carp, the feed coefficient is 1.9.

[0030] (6) Yield per mu

[0031] After 10 months of breeding, the pond was dried on April 5, 2012, and 323.77 kg of channa was captured, 6,132 tails, with a survival rate of 61.32%, an average weight of 52.8 grams, and an average yi...

Abstract

The invention discloses a culturing method for odontobutis obscuras, comprising the following steps of: arranging a fishpond: selecting a pond, arranging a fish nest in the pond, and cleaning and sterilizing the fishpond by using quick lime or bleaching powder; putting fish fries into the fishpond: putting preliminarily acclimated and cultured fish fires of odontobutis obscuras into the fishpond, and meanwhile, and putting river prawn, spotted silver carps and silver carps into the fishpond to carry out mixed culture; and breeding: breeding by using feeds with the protein contents of 35-40% for 10 months to obtain the odontobutis obscuras. By using the method provided by the invention, the culturing survival rate of the odontobutis obscuras is increased; in addition, the fish fries are bred by using a pellet feed, so that the culturing cost is reduced, the income of an aquatic product culturing farmer is increased, and the industrial development prospect of the odontobutis obscuras is wide.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for cultivating sandfish. Background technique [0002] Sand pond snakeheads belong to the order Perciformes, pond snakeheads, and sand snakeheads. They are commonly known as tiger head nerds, tiger head sharks, and Tupu fish. They are mainly distributed in lakes, reservoirs, and other waters in the Yangtze River, Pearl River, and Heilongjiang river basins in my country. , is an important small economic fish in China. [0003] The wild population of Channa namas is small and scattered. In addition, the individual is small and the natural yield is not high, which cannot meet the market demand. It takes a long time for the reproduction and hatching of sandfish, and it takes 15-21 days to hatch seedlings. Large-scale seedlings are restricted, let alone artificial breeding in ponds. Contents of the invention [0004] The present invention aims at solving one of the above techni...
