Technical Field
The utility model relates to a marine organism sampling device technical field, concretely relates to three-dimensional sampling device of stained living beings of netting.
Background
The netting fouling organisms refer to marine organisms attached to, inhabiting and growing on the netting of the aquaculture net cage, mainly including marine plants, marine animals and marine microorganisms, and can have serious influence on mariculture facilities. Common fouling organisms of the netting include marine macroalgae, benthic algae, bivalve shellfish, barnacles, ascidians, and the like. In the process of marine cage culture, a large amount of fouling organisms are attached to the netting to cause the blockage of the cage netting in different degrees, and on one hand, the blockage of the netting can reduce the water exchange in the cage, and the culture environment is deteriorated, so that diseases are frequently caused; on the other hand, the resistance of the net cage is increased, so that drifting and abrasion are caused, and the service life of the net cage is shortened. Therefore, the removal of fouling organisms attached to the netting becomes a great difficulty to be solved urgently in the net cage culture management.
The net coat biological cleaning method is to utilize omnivorous fishes to eat attachments (including organisms and residual baits) on the net coat so as to achieve the purpose of cleaning the net coat. Compared with the traditional net coat cleaning method, the net cage for cleaning the cultured fishes saves labor, time and money, can avoid safety risks brought by replacing or cleaning the net coat, and has wide popularization prospect.

The second method is a netting hanging method, namely, a netting is fixed on the netting, but the netting is easy to float on the water surface under the influence of sea current, the stability is insufficient, and in addition, because fouling organisms of the netting at different depths (including the surface of sea water) are different, the sampling range is very limited. The method has great influence on the population composition of the fouling organisms of the netting and the biomass investigation result.
