Example Embodiment

[0031] Example 1

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

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

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

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 artificial fish reefs or sea treasure reef bottom organisms and attached organisms. 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 sea treasure reefs can improve the seabed environment, retain organic matter, and increase the primary productivity of the sea area, providing a good environment for marine economic organisms. Nursery grounds and feeding grounds to promote the conservation and restoration of marine biological resources. [0003] Bottom organisms and attached organisms provide excellent bait for various fishery resources. The study of the succession of benthic and attached organisms is an important part of artificial reef research, which can reveal the maturity of artificial reef development. [0004] I...
