Abstract

The invention provides an artificial induced fertilization method for yellow croaker, which belongs to the field of biotechnology, and includes feeding the parent croaker with the stable composition prepared in the present invention during the cultivation period of the parent of croaker croaker, and carrying out nutritional strengthening , after the parents are sexually mature, carry out artificial egg collection to complete insemination, obtain fertilized eggs, hatch the fertilized eggs, and cultivate fry. The artificial oxytocin fertilization method of the present invention can adjust the final synchronous maturation of eggs and sperm to avoid the phenomenon of asynchronous and unsmooth spawning and ejaculation, avoid postpartum broodstock death loss, the female fish has a large amount of ovulation, and the male fish has high semen quality, which can improve the hatching rate and Effective hatching capacity to increase the output of fry; the composition is stable and easy to store, can increase the accumulation of fat, protein and total sugar in the testis and ovary, make the ovary and testis of the parents mature synchronously, and increase the ovulation capacity of the parent female fish.

Description

technical field

[0001] The invention belongs to the field of biotechnology, and in particular relates to an artificial induced fertilization method for yellow croaker. Background technique

[0002] Yellow croaker (Nibea albiflora), commonly known as yellow croaker, belongs to Perciformes, Chrysostidae, and genus Yellow croaker. Its body shape is similar to yellow croaker. It is a fish in the middle and lower waters of the sea, mainly inhabiting sandy mud bottoms It is an important multiplication and breeding species in the southeast coast of my country. Its meat is delicious, nutritious, and has high nutritional and medicinal value. The market demand on the rise. It is worth mentioning that the yellow croaker has an insect-resistant peptide gene that the large yellow croaker does not have, and has special immunity to stimulating Cryptocaryonia, and can be used as the preferred alternative breeding species in areas with high incidence of white spot disease.
