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 present invention relates to the technical field of aquaculture, in particular to a method for large-scale artificial breeding of Spanish Spanish mackerel, the method comprising broodstock domestication, broodstock intensive cultivation, broodstock reproduction, spawning and hatching, fry cultivation management, fish fry classification and pool management, Emergence and other steps; through scientific management and gradual domestication of broodstock, solve the problem of "die out of water" of horsefin; through intensified cultivation and reproductive regulation of broodstock, provide sufficient mature broodstock and high-quality fertilized eggs for large-scale breeding; Scientific seedling management, comprehensive treatment of seedling water and regulation of the seedling process, feeding fish fry open bait and safe biological feed and special artificial bait according to stage and ratio, graded and sub-pond management, etc., to improve the survival rate of seedlings and the quality of fry. The invention solves the key technology of large-scale artificial breeding of Spanish mackerel, has a high seedling survival rate, provides a high-efficiency seedling raising technology and new model for the industry, and promotes the efficient and healthy development of high-end seawater fish farming in my country.

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...
