Problems solved by technology
However, due to the lack of standardized breeding operations for broodstock of yellow croaker, without the strengthening of factors such as artificial temperature, light and nutrition, and the lack of timely harvesting and separation of natural spawning, the fertilization rate and hatching rate of fertilized eggs are low, and the seedlings The quality is difficult to guarantee, and the breeding efficiency is low

Embodiment
[0026] From 2010 to 2011, research on the cultivation and breeding of yellow croaker parents was carried out at the Xishan Experimental Field of Zhejiang Ocean Fisheries Research Institute. The method of the present invention was used to cultivate the yellow croaker parents and obtain fertilized eggs, which significantly improved the fertilization rate. Fertilization and hatchability of eggs. The invention provides a method for obtaining high-quality fertilized eggs of yellow croaker, which mainly starts from the following techniques.

An acquiring method for high-quality germ cells of spotted maigre belongs to the technical field of agricultural mariculture and comprises parent fish cultivation, germ cell collection and high-quality germ cell separation. The acquiring method for high-quality germ cells of spotted maigre plans a set of complete parent fish rearing technology, improves ovule living rate and fertilization success rate of ovules by grasping key link technical measures, and finally acquires high-quality germ cells. High-quality germ cells reach more than 91%, and hatchability reaches more than 93%.
Description
technical field [0001] The invention belongs to the technical field of agricultural mariculture, and in particular relates to a method for obtaining high-quality fertilized eggs of yellow croaker in the mariculture industry. Background technique [0002] Yellow croaker (Nibea albiflora), commonly known as yellow poke, belongs to the order Perciformes, the family Scrotoaceae, and the genus crocodile. It is a fish in the middle and lower waters of the coastal waters, and it is an important breeding and breeding species in the southeast coast of my country. It is mainly distributed in the coastal areas of China, the Korean Peninsula and the southern waters of Japan. In recent years, with the gradual depletion of natural resources of croaker, coupled with the establishment of artificial breeding of croaker and the establishment of large-scale seed cultivation technology, the artificial breeding of croaker has gradually emerged. However, due to the lack of standardized breeding ...
