Embodiment 1

[0018] The first step is to choose an ecological shrimp pond with a shellfish growth environment: from 2001 to 2007, an ecological shrimp pond with an area of ​​100 mu was selected in Zhuanghe Ocean Village, Dalian. The ecological shrimp pond has easy drainage; the bottom is hard sand bottom; water depth 1.5m-1.8m, seawater salinity 20-32, pH7.60-8.60. The pool was cleaned here to eliminate harmful organisms; regular fertilization and watering kept the water in the ecological pool "fertile, alive, tender, and refreshing", and the transparency was controlled at 30-40cm.

[0019] The second step is to choose healthy shellfish individuals as parents: generally choose 1-year-old or 2-year-old shellfish individuals as parents, including Philippine clams, green clams, hard-shell clams, thin-film mirror clams, four-cornered clams, and wide-shell whole sea clams. Bamboo shoots; the parents are required to be neat in size, with intact shells, strong vitality, and vigorous feeding.

Abstract

The invention discloses an eco-maturing method of the parent shellfish of a common mudflat shellfish. The method comprises the steps: an eco-shrimp with suitable environment is selected; a health shellfish individual is adopted as a parent individual; the maturing of a seed shellfish is carried out by the breeding method of bottom sowing; and the sexual gland development status is observed regularly till the sexual gland is fully grown and the mature period is determined. Therefore, the sexual glands of the shellfish can be matured in advance and a very long mature period can be maintained. The method can effectively prolong the breeding season of the shellfish by 2 to 3 months, improve the reproductive capacity by 3 to 5 times and lay a good foundation for the genetic breeding and seed breeding of the shellfish. The method has the characteristics of easy and convenient operation and easy popularization.

Description

technical field [0001] The invention relates to a parental ecological maturation-promoting technology for common tidal flat shellfish, in particular to a method for placing seed shellfish in a shrimp pond for ecologically promoting ripening. Background technique [0002] The sexual maturity of most shellfish has stages throughout the year, that is, there is a certain breeding season (breeding period). The breeding season (breeding period) of shellfish refers to the environment (mainly water temperature) of this season of the year, which is suitable for the parents to lay eggs and ejaculate. Generally, from the beginning of spawning to the end of the end, this period becomes the best time for this type of shellfish. breeding season. During the breeding season of shellfish, when spawning and ejaculation reach the highest peak, it is its breeding season. The breeding seasons of different shellfish or the same shellfish in different regions are very different, and the breeding...
