A kind of attachment base for thick-shelled mussel spat

Abstract

The invention discloses a thick-shelled mussel spat attachment base, which includes a mounting frame and a corrugated plate. A number of fixed guide rail groups are arranged at intervals from top to bottom on the left and right sides of the inside of the mounting frame. The guide rail group is composed of two oppositely arranged fixed guide rails. The fixed guide rails are arranged obliquely. The inclined angle α between the fixed guide rails and the horizontal plane is 5~30°. The corrugated plate is from the higher end of the fixed guide rails to the The lower end is inserted into the installation frame, and the direction of the corrugation of the corrugated plate is consistent with the direction in which the corrugated plate is inserted into the installation frame. Slight shaking can occur under the action, and an angle limiting structure is set between the corrugated plate and the guide rail to limit the shaking angle of the corrugated plate. The invention has the advantages of simple structure, convenient installation, smooth water flow and long service life, and is beneficial to spat attachment.

Description

technical field [0001] The invention relates to an attachment base for raising shellfish seedlings, in particular to an attachment base for thick-shell mussel juveniles. Background technique [0002] Thick-shelled mussels, commonly known as Maohaihong, mussels, and Qingkou, belong to the mollusk phylum, clavalobranches, heterocylindromes, and mytilidae. They are warm-temperate benthic bivalve molluscs in the coastal waters and are widely distributed along the coasts of the East China Sea and the Yellow and Bohai Seas. Sea area, the main production area is the sea area of ​​Zhoushan, Zhejiang. Thick-shell mussels are large, fast-growing, delicious, nutritious, and have nourishing and health-care effects. They are very popular in domestic and foreign markets, and their prices are much higher than those of mussels and blue mussels. [0003] The main breeding area of ​​mussels in my country is in Zhoushan, Zhejiang Province, and the source of seedlings is all indoor artificial ...

AI Technical Summary

Problems solved by technology

The attachment base has the following defects: (1) The corrugated plates in the attachment base are placed vertically, and the two ends of the corrugated plates are installed in the slots on the side plates, so that the water flow in the attachment base is not smooth and the water exchange is relatively slow. (2) The spat of thick-shelled mussels will often break the silk and move the position. The corrugated plate in the attachment base is placed vertically, and it is difficult for the spat to stay on the corrugated plate after breaking the silk. (3) The corrugated plates need to be aligned with the corresponding card slots on the side plates and inserted one by one. It is very inconvenient to install, and it is easy to put the corrugated plates on the corrugated plates when removing them. spat
