Natural sea area large-scale ecological breeding method of stichopus japonicus

Abstract

The invention relates to a natural sea area large-scale ecological breeding method of stichopus japonicus, belonging to the field of aquiculture. The method can realize large-scale stichopus japonicus seedling breeding at the natural sea area by the steps of selecting and culturing parent stichopus japonicus, daily management of the parent stichopus japonicus, egg taking and incubating, culturing the young, culturing young stichopus japonicus, classifying offspring seeds and temporary culturing. The method solves the problems of degraded seedling quality, reduced production quality of the seedlings, gradual increment of stichopus japonicus diseases, high energy consumption of a seedling breeding room and the like in the process of seedling cultivation in the existing artificial seedling breeding room, overcomes the technical prejudice that sea cucumber seedlings can not be cultured at the natural sea area in the traditional view, breaks through the inherent thinking set, changes the traditional production way of the artificial seedling breeding room, and can realize ecological breeding in the natural sea area. Furthermore, the method has the remarkable advantages of high survival rate, no pollution and chemical dosing as well as being nuisanceless.

Description

technical field [0001] The invention belongs to the field of aquaculture, in particular to a seedling raising method of sea cucumber. Background technique [0002] Sea cucumber, commonly known as sea cucumber, also known as Apostichopus Japonicus (Selenka), is a kind of echinoderms, belonging to the phylum Echinoderm, Sea cucumber, Apostichopus, Aposticaceae, Apostichopus genus. Apostichopus japonicus is the only recorded edible sea cucumber in my country that is distributed in the temperate zone of the Yellow Sea and the Bohai Sea. It is also the sea cucumber with the best quality and the highest economic value in the world. It is mainly distributed in the shallow sea along the North Pacific coast, Hokkaido, Japan, and the east coast of North Korea. And the far east coast of the Soviet Union, in my country, it is mainly distributed in Shandong Peninsula and Liaodong Peninsula and other places. [0003] In recent years, my country's sea cucumber breeding industry has develop...

Problems solved by technology

[0005] In order to solve the problems of germplasm degradation, seed production quality decline, sea cucumber diseases gradually increasing, and high energy consumption in the nursery in the existing artificial nursery, the inventors overcome the traditional concept that sea cucumber seedlings cannot be scaled up in natural sea areas, The technical prejudice of large-scale cultivation has broken the inherent thinking pattern, changed the traditional artificial nursery production method, and carried out ecological seedling cultivation in natural sea areas; Ecological seedling raising method
