Problems solved by technology

[0005] At present, there is no moire grouper (♀) and saddle grouper at home and abroad. According to reports on hybrid breeding, although there are successful cases of distant hybridization in other groupers, most of them are hybrids between tropical or subtropical species, and it is difficult to solve the problem of breeding new species of grouper in warm temperate zones and broaden the scope of their breeding. scope

Embodiment Construction

[0023] Describe technical content of the present invention in detail below in conjunction with example:

[0024] A method for hybrid breeding of moire grouper females and saddle grouper males, the steps comprising: parent selection, cultivation facilities and feeding, parent water temperature regulation, parent nutrition strengthening, parent induced labor, artificial insemination and hatching ;

[0025] 1) Parent selection:

[0026] This experiment was carried out in June 2014. Healthy moiré grouper with normal body shape, no disease and strong vitality over 4 years old was selected as the female parent; healthy saddlefish with normal body shape, no disease and strong vitality at the age of 6-7 were selected. grouper as the male parent;

[0027] 2) Parental cultivation:

[0028] a. The male and female parents are respectively placed in different parent fish breeding ponds for cultivation, and the moire grouper cultivation pond has an area (5m×7m) of 35m 2 The four corners...

Abstract

The invention relates to an epinephelus radiates female fish and epinephelus lanceolatus milter crossbreeding method, which comprises the steps of parent selection, parent water temperature regulation and control, parent nutrition enhancement, parent hasten parturition, artificial insemination and incubation; the epinephelus radiates female fish is warm middle-lower layer fish with large individual and high growth speed; the epinephelus lanceolatus fish is tropical and sub-tropical region warm water fish with high growth speed and high nutrition value; after the crossbreeding, the excellent later generations with high growth speed and wide temperature adaptation range can be obtained.

Description

technical field [0001] The invention belongs to seawater fish breeding technology, and relates to a hybrid breeding technology of moire grouper and saddle grouper. Background technique [0002] Moire grouper (Epinephelusmoara) and saddle grouper (E.lanceolatus) belong to perciformes (Perciformes), fin family (Serranidae), grouper subfamily (Epinephelinae), grouper genus. Moire grouper, commonly known as oil spot, is a large warm-temperature marine bottom fish, mainly distributed in the western North Pacific Ocean, from the Vietnam Sea to the South China Sea, the East China Sea to the coasts of Japan and South Korea, and has a wide range of temperature adaptation. Saddle band grouper, commonly known as dragon grouper and gentian grouper, is the largest grouper among grouper fishes. It is famous for its large size and fast growth, so it is also called "spot king". Saddle grouper is a kind of edible fish with high economic value. It belongs to warm water fish. It is widely dis...
