Suspended aquaculture device capable of moving shellfish for fattening and collecting infant shellfish

Abstract

The invention discloses a suspended aquaculture device capable of moving shellfish for fattening and collecting infant shellfish. The suspended aquaculture device can be freely enlarged or reduced according to the proportion and comprises a square outer framework suspending on the water surface; cross bars are arranged on the outer frame at a distance of 30-40cm; the crossed parts of every two cross bars are firmly bound; iron hooks are respectively hung at the crossed parts; the periphery of the outer frame is firmly connected by tenons, bolts and steel plates; the cross bars are firmly connected with the periphery of the framework by tenons, bolts and steel plates; four corners or frame sides of the breeding device are supported by the buoyancy of closed circular and square floaters; one corner of the suspended aquaculture device is connected with a nylon rope ring with the diameter being 4-5cm; the nylon rope ring is firmly sleeved and tied in a pile column which is vertically and deeply buried at the bottom of a pond or the sea bed; and the nylon rope ring can freely lift along the height of the water level, so that the fatten shellfish hung on the iron hooks moves following the movement of the device. The suspended aquaculture device for collecting infant shellfish and fattening belongs to an environment-friendly and low-carbon type aquaculture device.

Description

technical field [0001] The invention relates to a suspension culture device that can make shellfish "swim" to fatten and pick seedlings, especially to solve the problem of lack of oxygen and problems caused by the inability to ensure the supply of bait organisms and sludge deposition during fixed fattening and seedling picking of shellfish. Gill mold fungal infection problems occur. Moreover, the production technology of the whole device is easy to master; the production cost is low; only one end of the device is fixed, which avoids the frontal impact of wind and waves, has strong wind and wave resistance, and is suitable for the needs of different aquaculture water bodies. Therefore, the suspended seedling-picking and fattening device is an environmentally friendly and low-carbon aquaculture device. Background technique [0002] The amount of aquaculture in my country has accounted for more than 70% of the world. By 2008, the output of aquatic products in my country had re...
