Breeding and cultivation method of hybrid Oxyeleotris marmoratus Bleeker

Abstract

The invention belongs to the technical field of breeding and cultivating, in particular to a breeding and cultivating method of hybrid Oxyeleotris marmoratus Bleeker. The method comprises four aspects of totally artificial propagation, fry rearing, adult fish cultivation production and fish disease prevention and cure on hybrid Oxyeleotris marmoratus Bleeker, wherein the totally artificial propagation is characterized in that Oxyeleotris marmorata and Oxyeleotris lineolatus are crossed into hellbender which is the improved variety of the hybrid Oxyeleotris marmoratus Bleeker by a scientific method by utilizing the advantages of two fishes of the Oxyeleotris marmorata and the Oxyeleotris lineolatus; the hellbender gathers the bright color, the good external appearance and the tender and smooth meat texture of the Oxyeleotris marmorata, avoids the defects that the original fish variety is afraid of light, has the habit of hiding in soil and and is fierce and avoids the murder phenomenon that big fishes swallow little fishes and gathers the advantages that the Oxyeleotris lineolatus has gentle nature, does not hide in the soil, is not afraid of light and is not fierce; the hellbender is easy to feed and catch and has high yield; moreover, the fry price of the hellbender is three times the fry price of the Oxyeleotris marmorata, and the price of the commodity adult fish is higher than 30 percent the price of the Oxyeleotris lineolatus; and the hellbender has obvious economic benefits, is welcomed by raisers and is also welcomed by eaters.

Description

technical field [0001] The invention belongs to the technical field of breeding and breeding, and in particular relates to a breeding and breeding method of hybrid bamboo shoot shellfish. Background technique [0002] With the improvement of people's living standards, the food on the dining table must not only have high nutritional value, but also have the requirements of color, aroma and taste. , docile in nature, not afraid of light, not submerged in mud, but it looks bad, the fish body is gray-black, and the color, aroma and taste are not good when eaten, which affects people's interest in eating; cloud spot, which is also a valuable food fish Jiantang snakehead, also known as Thai bamboo shoot fish, has a good appearance and a yellow body. Although it meets the color that people eat, its fragrance is not as good as that of Australian bamboo shoot fish. Eating small fish of the same kind is not easy to feed, and the yield is low. Therefore, it is possible to hybridize Au...

[0002] With the improvement of people's living standards, the food on the dining table must not only have high nutritional value, but also have the requirements of color, aroma and taste. , docile in nature, not afraid of light, not submerged in mud, but it looks bad, the fish body is gray-black, and the color, aroma and taste are not good when eaten, which affects people's interest in eating; cloud spot, which is also a valuable food fish Jiantang snakehead, also known as Thai bamboo shoot fish, has a good appearance and a yellow body. Although it meets the color that people eat, its fragrance is not as good as that of Australian bamboo shoot fish. Eating small fish of the same kind is not easy to feed, and the yield is low. Therefore, it is possible to hybridize Australian bamboo shoots and Thai bamboo shoots to make their colors, aromas, and tastes complement each other. It has been a research topic in the aquaculture industry for many years to overcome the huge economic benefits.
