Problems solved by technology

[0002] The reproduction of white mullet is a very complicated work. In the prior art, the eggs of white mullet are underdeveloped due to lack of nutrition, the amount of eggs is small, the eggs of female fish are immature, and the eggs are hatched intensively, resulting in low hatching rate. The large zooplankton white mullet cannot be eaten, but will be bitten to death by zooplankton

Abstract

The invention discloses a method for breeding and increasing the yield of white mullets, which comprises the following steps of: S1, selecting breeding fish for the first time; S2, selecting the breeding fish for the second time; S3, after selecting parent fish for the first time, putting the parent fish into a sterile parent fish pond for independent feeding; S4, culturing second parent fish on the basis of selecting good parent fish for the second time; S5, selecting the parent fish during spawning of the white mullets, and selecting the parent fish with large mature body sizes; S6, carryingout spawning induction medicine injection on female fish for two times, and carrying out one-time injection on male fish; S7, placing the spawned parent fish in a greenhouse for spawning and hatching; S8, two days after the fish fries are ovulated, transferring the fish fries to a water flower fish pond for culture; S9, adding fresh water, adding photosynthetic bacteria and phosphate fertilizer,and feeding zooplankton; S10, feeding minced fish meat, finishing fish fry cultivation, and separating the fish fries to different ponds for adult fish cultivation. According to the invention, a secondary injection spawning induction method is used, so that the eggs of the female fish are more mature, and the hatching rate is high; the eggs are protected by the parent fish for hatching, and the survival rate is improved.

Description

technical field [0001] The invention relates to the technical field of white mullet reproduction, in particular to a method for increasing production of white mullet. Background technique [0002] The reproduction of white mullet is a very complicated work. In the prior art, the eggs of white mullet are underdeveloped due to lack of nutrition, the amount of eggs is small, the eggs of female fish are immature, and the eggs are hatched intensively, resulting in low hatching rate. The large zooplankton white mullet cannot be eaten, but will be bitten to death by the zooplankton. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a method for increasing the reproduction and production of white mullet. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A method for increasing production of white mullet, comprising the following s...
