Embodiment

[0013] Example: refer to Figure 1 to Figure 4 , fast fishing net clothing, has the main body net 51 that approximately is closed cylinder after opening, and wherein: the upper center of main body net 51 has a smaller opening, and opening is connected with net neck 52; There are detachable snap joint parts for quick connection to the external rigid frame. The net neck 52 that the opening is connected can keep an opening on the main body net 51 upper side and the water surface in the breeding process at ordinary times, which is convenient for management during production. The semi-submersible tower 1 with the external rigid frame can stop the effect of waves on the net neck 52 . When collecting the net, you only need to pull the net neck 52 with the net pulling machine to quickly complete the net collection. If it is necessary to catch a part of fish in the breeding process, then the fish suction pump can be stretched into the main body net 51 to suck fish by the net neck 52,...

Abstract

The invention discloses a netting for fast collecting fish, wherein the netting has a main net which is similar to a closed cylinder after being unfolded; a relatively small opening is formed at the upper centre of the main net; the opening is connected with a net neck; and a detachable sklipknot skipknot connecting component which can be fast connected with an external rigid framework is arranged on an external rope of the main net. An opening between the upper side of the main net and athe water level can be kept during thea breeding process at ordinary times by the net neck connected with the opening, so that convenience in management during production is provided. The external rigid framework is provided with a semi-submersible tower which can prevent waves from acting on the net neck. The netting for fast collecting fish disclosed by the invention overcomes the defect that the strength of a net cage framework is subjected to a fatigue damage for the reason that the conventional net cage main nets which are located on the water level are easy to fluctuate with waves. Therefore, the netting for fast collecting fish has the advantages of novel structure, good laying stability, strong wind wave resistance, large carrying capacity, good fish protection effect, and convenience in management.

Description

technical field [0001] The invention relates to large-scale aquaculture net cage equipment in open seas, in particular to net clothing for fast fish collection. Background technique [0002] Aquatic products are one of the main sources of animal protein intake for people. In the long run, aquatic products and animal products will take the leading role in non-staple food consumption. Aquatic products will not only become one of the main sources of animal protein intake for people, but also alleviate the problems of population increase, land decrease and food shortage. Offshore aquaculture is far away from the shore, and transportation and aquaculture management are quite different from traditional aquaculture models. Aquaculture management must be realized based on automation, intelligence, modernization, and mechanization. Traditional means of artificial feeding, inspection, sampling and analysis are far from meeting the needs of the development of the offshore aquaculture ...
