Embodiment 1

[0022] 1) Broodstock cultivation conditions: 3-5 mu of earthen ponds are used for broodstock cultivation ponds. At the beginning of April every year or about 5 days before the induction of labor, disinfect with a dry pond of quicklime with a concentration of 100kg / 667㎡; fill with water after splashing for 2 days, the water depth is greater than 1.5m, and stock broodstock or reserve broodstock after 7 days of soaking, 200-300 / 667 ㎡, the ratio of male to female is 1:1-2.

[0023] 2) Broodstock breeding: During broodstock breeding, feed homemade soft pellet feed containing about 35% crude protein, 1-2 times a day, that is, 7:30-8:30, 16:00-17:00, each time The amount is 1%-2% of the total weight of the fish; under normal circumstances, the water is changed 2-3 times a month, and the water is changed about 10cm each time; 30-60 days before the induction of labor, flush the water for 2-3 hours a day to promote Gonadal development of the parent.

[0024] 3) Artificial induction of labo...

Abstract

The invention discloses a total artificial batch breeding method of striped bass. The method comprises the following steps of: after the parent fishes or the standby parent fishes are bred intensively to mature, performing artificial propagation by using an oxytocic, and then performing artificial incubation, fry breeding pool preparation, primary breeding and secondary breeding so that all the fries have the full length being more than 2.0 cm; and then, continuously throwing bait to the fry pool until the fishes grows big. The total artificial batch breeding method of striped bass improves fertility rate and hatchability, and also improves the fry breeding survival rate and increases the annual fry breeding quantity; in addition, the total artificial breeding effect is obviously improved and the annular fry breeding quantity reaches a large-scale breeding level.

Description

[0001] technical field [0002] The invention relates to the technical field of fish artificial breeding, in particular to a method for fully artificial batch breeding striped bass. [0003] Background technique [0004] Striped perch has tender meat, no intermuscular spines, rich nutrition, wide temperature, wide salt, fast growth and other characteristics, suitable for intensive farming. It is of great significance to solve the artificial batch breeding technology of striped perch, carry out large-scale nursery production and breeding demonstration of striped perch, and provide a large number of high-quality seedlings and technical guarantee for the further promotion and breeding of striped perch, which is of great significance to improve the economic benefits of breeding. [0005] my country's Guangdong, Fujian and other provinces and cities have successively introduced striped perch for trial breeding, and have broken through the artificial breeding technology successiv...
