Embodiment 1

[0032] The collection device of the present invention is suitable for small artificial fish 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 to the sample collection bag 4, and the other end is evenly distributed with fixing holes 7, and the fixing rope 8 passes through the fixing hole 7 and is fastened on the steel ring 6. Circle 6 pulls out load-bearing rope 5 by the cord buckle on it.

[0034] The nets are from top to bottom successively an upper net 1, a middle net 2, and a lower net 3, wherein 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 netting 1 is made of canvas material or soft texture, low water permeability and wear-resistant material, the middle netting 2 is made of nylon or polyethylene mesh, and the lower netting 3 is made of sieved silk. The net 2 in the middle is made of at least one ...

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...
