Multilayer stereoscopic suspension sea cucumber attachment substance

Abstract

The invention relates to a multilayer stereoscopic suspension sea cucumber attachment substance which is a cylindrical semi-closed net cage which uses upper, middle and lower layers of round porous plastic frame sheets as support frames and is surrounded by a netting with a mesh number of 20 to 40. The circular arc surface of the cylindrical semi-closed net cage is semi-surrounded by the netting; an opening with a width of 5cm is reserved; the net cage has a plane diameter of 30 to 40cm and a height of 60cm. Two cylindrical semi-closed net cages are clung to each other and are connected to form one group of attachment substances; the upper layers of porous plastic frame sheets of the two net cages are respectively connected to the same buoy with a diameter of 5 to 10cm by nylon ropes; the height from the buoy to the top surface of each net cage is 30cm. The lower layers of round porous plastic frame sheets of the two cylindrical semi-closed net cages are respectively connected with one circle of drooping mesh with a height of 30cm; two ceramic net weights are respectively tied at the middle lower section position of each dropping mesh. The multilayer stereoscopic suspension sea cucumber attachment substance solves the problems of small attachable area of the attachment substance and low utilization rate of aquatic water in a sea cucumber aquaculture pond and is suitable for high-density aquaculture of the sea cucumber pond.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a multi-layer three-dimensional suspended sea cucumber attachment base. Background technique [0002] Sea cucumber aquaculture is the main aquaculture industry in the northern coastal areas of my country in recent years, and the aquaculture output value continues to increase. Except for a small part of the artificial breeding of sea cucumbers in the natural sea area, most of the rest are distributed in intertidal zone cofferdam culture and beach pond culture with tidal conditions along the coast. Pond culture currently occupies the vast majority of the sea cucumber culture area in my country. part. Sea cucumber pond culture needs to lay sea cucumber attachment bases on the bottom of the pond to provide sea cucumbers with shade and shelter and attached bait for sea cucumbers to eat. Most of the aquaculture ponds now use a long cage-like attachment base laid on the bottom of the pond. ...
