Shallow sea culture method and device for scapharca broughtonii

Abstract

The invention discloses a shallow sea culture method and device for scapharca broughtonii. The culture method comprises steps as follows: firstly, scapharca broughtonii seedlings are cultured, a proper culture sea area is selected, then the scapharca broughtonii seedlings are placed into a scapharca broughtonii culture device, and the device is buried in the sea floor of the scapharca broughtonii culture sea area; during culturing, all that is required is to check the safety of the culture device regularly, and a qualified scapharca broughtonii product is obtained after 1.5-2 years of culture. The scapharca broughtonii culture device is a net cage and comprises a cuboid frame and polyethylene net pieces surrounding the outside of the frame, polyethylene ropes are arranged on four edges of the top surface of the frame and tied on floating ropes, hanging stones are hung on four edges of the bottom surface of the frame and used for fixing the device; cross beams are arranged on six sides of the frame and used for supporting the frame. With the adoption of the culture method and device, the high scapharca broughtonii catching rate can be guaranteed, the scapharca broughtonii can be prevented from being attacked by enemies, the high scapharca broughtonii survival rate can be guaranteed, the finished scapharca broughtonii product quality is improved obviously, the good economic benefit is brought, and new vitality is injected to the shellfish culture industry.

Description

technical field [0001] The invention relates to a method and a device for cultivating tidal flat shellfish, in particular to a method and a device for cultivating cockles in shallow seas. Background technique [0002] Kui clam is a large clam with a shell height of 8 cm, length 9 cm, and width 8 cm, commonly known as red shell.

Cockles are one of the main shellfish that earn foreig...

AI Technical Summary

Problems solved by technology

Bottom sowing multiplication method is adopted, the clams are easily attacked by predatory organisms, resulting in low survival rate, and seabed harvesting operation is troublesome, which may easily lead to a low return capture rate of clams, and the input of manpower and material resources is large, so the yield and benefit are not good. High; cockles are benthic shellfish, and raft cage culture is a kind of hanging raft culture, which cannot meet the environmental requirements for the growth of cockles, so cockles can only be cultured to a size of 2-4cm. size, it is difficult to reach the adult size, so it is difficult to meet the market's requirements for the quality of clams, the market value created is low, and the economic benefits are not high. difference, so the survival rate of clams is also lower
