Embodiment 1

[0075] A kind of large-scale artificial breeding method of Spanish mackerel of the present embodiment, comprises the following steps:

[0076] Step 1, the domestication of the parent fish of horsefin:

[0077] Step 1, the domestication of the parent fish of horsefin:

[0078] a) Select large and strong parents from the breeding pool where the parents are planned to be selected, and the ratio of male to female is 1:1;

[0079] b) The selection process must be handled lightly, bagged with water, one tail per bag, packed in a foam box, transported by car, transported to the nursery at the fastest speed, and placed in the parent breeding pool for cultivation. The depth of the parent cultivation pond is 1.5 Rice, put in 10ppm platinum combination multivitamin, 20ppm black grain treasure;

[0080] c) Feeding is fed 3 times a day, and the feeding time is 7:30 and 18:30; the feed is a special compound feed for Spanish Spanish mackerel, and the platinum combination vitamins accountin...

Abstract

The invention relates to the technical field of aquaculture, in particular to a large-scale artificial propagation method for mackerels. The method comprises the steps of parent fish domestication, parent fish intensifying culture, parent fish reproduction, egg laying and incubation, fry breeding and management, fry grading and sub-pool management, fry selling and the like. Parent fishes are subjected to scientific management and gradual domestication, and the problem that the mackerels die instantly leaving water is solved. By means of intensifying culture and procreation regulation and control on the parent fishes, enough mature parent fishes and high-quality oosperms are provided for large-scale fry breeding; by means of scientific fry breeding management, fry breeding water is comprehensively treated, the fry breeding process is regulated and controlled, the mackerels are fed with fry initial bait, safe biological feed and special artificial food stepwise in proportion, grading andsub-pool management is adopted, and the fry breeding survival rate and the fry quality are improved. According to the large-scale artificial propagation method, the key technology of large-scale artificial breeding of the mackerels is solved, the fry breeding survival rate is high, an efficient and new fry breeding technology and a new mode are provided for the industry, and efficient and healthydevelopment of high-end seawater fish breeding of China is promoted.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for large-scale artificial breeding of Spanish Spanish mackerel. Background technique [0002] Spanish Spanish mackerel belongs to the bony fish class, scombroid family. There are many types, the common ones are Chinese mackerel, blue-spotted mackerel, spotted mackerel, Kangshi mackerel and so on. It is mainly distributed in the western part of the North Pacific Ocean. It is found in both the Yellow Sea, the Bohai Sea and the South my country Sea. It is a warm pelagic fish. Spanish Spanish mackerel is delicate in texture, delicious in taste, rich in nutrition, rich in protein, vitamin A, minerals and other nutrients, and is a high-quality seafood with high economic value. [0003] In order to improve the output of Spanish Spanish mackerel, people continue to carry out the research of artificial breeding technology. The current artificial breeding mainly has proble...
