Problems solved by technology

[0004] However, in the actual breeding process, it is often found that there are still a lot of dead eggs and dead seedlings after insemination, and the growth period of fry is relatively long. Therefore, the existing patented method has been unable to realize the large-scale breeding of spiny head plum boy
It is impossible to obtain fertilized eggs in batches and cultivate enough fry

Embodiment 1

[0041] Embodiment 1: Carry out artificial breeding with wild spiny head plum boy.

[0042] On May 2 of the lunar calendar, when there was a big tide, wild plum boy fish was caught in the Feiyun River Estuary of Ruian as a parent. The natural surface water temperature of the sea area was 24.2°C, the water depth was 8.7m, the pH was 8.18, and the salinity was 23.6. After the wild spiny head fish is caught on board, the ratio of the total length of the female fish to the length of the gonad is 1:0.28, the body length is more than 10cm, the weight is more than 35g, the abdomen is bulging, the vitality is good, there is no damage, the body is strong, and the gonads are mature. The male and female individuals of the spiny head plum boy were used as parents. Choose a male to female ratio of 2:1. The ovaries of the selected female fish are large and long cystic, and the ovaries account for more than 20% of the body weight; the thick surface of the testis of male fish should have obvi...

Abstract

The invention discloses a method for breeding of collichthys lucidus. The method comprises the following steps of a, obtaining and selecting parent fishes; b, obtaining high-quality sperms and eggs; c, obtaining fertilized eggs in batches; d, breeding fries; and e, breeding the fries in different ponds in the later period of breeding. According to the method, the perfectness ratio of the sperms and eggs is increased by changing a traditional sperm and egg taking mode, the sperm and egg fertilization rate and hatching rate under the same proportion are increased, the nutritional state of the fries in the breeding period is guaranteed by gradually increasing bait varieties, the survival rate of the fries is increased, and the artificial breeding method for the collichthys lucidus in the scheme provides powerful support for breeding and germplasm resource protection.

Description

technical field [0001] The invention relates to the field of fish culture, and more specifically relates to a method for raising seedlings of spiny-headed plum boy. Background technique [0002] Plumfish is one of the small economic fishes in the coastal waters. The black-branched Plumfish is mainly distributed in the Bohai Sea, the spiny-headed Plumfish is mainly distributed in the Yellow Sea and the East China Sea, and the East China Sea has the largest production. It likes to live in the junction of salty and fresh water in estuaries. The speed is fast, the temperature is suitable, and the range of salt is wide. The fishing season is from April to June and September to October every year. Its meat is tender and delicious. It is one of the high-end aquatic products that coastal residents like to eat. In recent years, due to overfishing , water pollution, environmental damage and other reasons have led to a substantial reduction in the natural resources of plum boy fish. ...
