Abstract

The invention provides an artificial hatching method for Leopard Coral Grouper. The artificial hatching method comprises the steps of setting a net cage, managing hatching water quality, collecting and hatching fertilized eggs and intensively breeding fish fries. The water quality is reasonably regulated according to the living habit of the Leopard Coral Grouper, and an enhancer and artificial baits are matched for hatching, so that the hatching rate and survival rate of the hatched fish fries are high.

Description

technical field [0001] The present invention relates to the field of aquaculture, in particular to an artificial hatching method for the eastern star spot. Background technique [0002] Eastern star spot, Plectropomus leopardus (Lacepède, 1802), also known as leopard-printed thorn perch, piebald thorn perch, seven-star spot, red stripe, etc., belongs to the order Perciformes, Scorpidae, Grouper subfamily, genus Pleuropomus, It is mainly distributed in the tropical waters of the Indian Ocean and the Pacific Ocean, and is distributed in the east coast and southern seas of Hainan, but the number is rare. Dongxingban is rich in nutrition, tender and delicious, and has the characteristics of high protein, low fat, and low cholesterol. It has high economic value, and because of its bright color, it has good ornamental value. market prospects. [0003] At present, the hatching production of eastern starfish fry is low, and the hatched fry have high pathological changes and low su...
