Embodiment 1

[0032] The collection device of the present invention is suitable for small artificial reefs, see figure 1 , figure 2 ,

[0033] The collection device is composed of a steel ring 6, a rope and a net; one end of the net is connected with the sample collection bag 4, and the other end is evenly provided with fixing holes 7, and the fixing rope 8 passes through the fixing holes 7 and is fastened to the steel ring 6. The loop 6 pulls out the load-bearing rope 5 through the rope buckle on it.

[0034] The nets are, from top to bottom, an upper net 1 , a middle net 2 , and a lower net 3 , wherein the upper net 1 is connected with the steel ring 6 , and the lower net 3 is connected with the sample collection bag 4 . The upper mesh 1 is made of canvas material or a material with soft texture, low water permeability and wear resistance, the middle mesh 2 is made of nylon or polyethylene mesh, and the lower mesh 3 is made of screen silk. The middle mesh 2 is made of at least one lay...

Abstract

The invention discloses an acquisition device, in particular to an acquisition device for epibenthos and settled organisms of artificial fish reefs or sea treasure reefs. The acquisition device comprises a steel ring, a rope and a netting, wherein one end of the netting is connected with a sample collecting bag; the other end of the netting is connected to the steel ring through the fixed rope; and the steel ring can be used for drawing out a head rope through a rope fastener on the steel ring. The acquisition device disclosed by the invention is netting gears which are mutually separated andassociated; and according to the acquisition device, the species, the quantity and the efficiency for acquisition of the settled organisms and the epibenthos can be remarkably increased, the loss andthe escape of the epibenthos and the settled organisms are reduced and the epibenthos and the settled organisms can be acquired conveniently, efficiently and quickly.

Description

technical field [0001] The invention relates to a collection device, in particular to a collection device for organisms and attached organisms on the bottom of artificial fish reefs or rare sea reefs. Background technique [0002] With the development of economy and society, due to overfishing and offshore pollution, the marine ecological environment has been seriously damaged. Artificial reefs and marine reefs can improve the seabed environment, retain organic matter, and at the same time increase the primary productivity of the sea area, providing good marine economic organisms. The nursery and bait grounds, promote the conservation and restoration of marine biological resources. [0003] The organisms and attached organisms on the bottom provide excellent bait for various fishery resources. The study of the succession of organisms on the bottom and attached organisms is an important part of the research on artificial reefs, which can reveal the maturity of artificial ree...
