A kind of shallow sea attachment type shellfish breeding device and using method thereof

Abstract

The invention provides a shallow sea attachment type shellfish culture and proliferation device and a use method thereof, and belongs to the technical field of aquatic culture and proliferation. The device comprises a base, fixing rods, auxiliary rods and attachment ropes. The base is a square flat plate and is provided with the eight fixing rods. Annular clamping grooves are formed in the fixingrods, the attachment ropes wind all the annular clamping grooves in the device from the low end to the top end, the two ends of the attachment ropes are knotted, and binding ropes are arranged on theattachment ropes and used for fixing shellfish fry ropes. The auxiliary rods are stainless steel rods with holes formed in the two ends and the middles. The upper ends of the fixing rods can completely penetrate into the holes according to the positions and the sizes of the holes, and screws at the upper ends of the fixing rods are matched with corresponding nuts to fix the auxiliary rods. Fixed-point accurate delivery can be achieved, fry cannot be washed off by ocean currents, meanwhile, damage of starfishes and other hostile organisms to bottom sowing shellfishes is avoided, and the survival rate and the sea area utilization rate are increased.

Description

technical field [0001] The invention belongs to the technical field of aquaculture enhancement, and specifically relates to a shallow sea attachment type shellfish enhancement and cultivation device and its application method. Background technique [0002] Shellfish farming in my country occupies an important position in the aquaculture industry. At present, raft culture and bottom-sowing culture are the two main methods of shallow sea shellfish culture in my country. Among them, most of the bottom-sowed cultured species are buried shellfish such as cockles and Philippine clams; the raft-type cultured species are mainly attached shellfish. Species, including mussels, scallops, etc., of course, also include cockles, oysters, abalone and other species that are raised in scallop cages and other equipment. Bottom-sowing culture of attached shellfish is difficult, mainly because of the limited breeding area suitable for bottom-sowing, lack of bottom-sowing culture technology, and...

AI Technical Summary

Problems solved by technology

Bottom-sowing cultivation of attached shellfish is difficult, mainly because of the limited breeding area suitable for bottom-sowing, lack of bottom-sowing cultivation technology, and difficulty in harvesting, etc.

With my country's increasing emphasis on marine environmental protection, marine ranching is developing rapidly, and traditional farming methods in many sea areas are changing to resource conservation-based multi-farming methods. However, there has been a lack of better bottom-sowing multi-farming equipment and methods for attached shellfish.
