Far-deep sea fishing method

Abstract

The invention discloses a far-deep sea fishing method, which comprises the following fishing steps: (1) route designation: determining fish types to be fished, formulating routes for habitats of the fish types, and finding out the appearing and disappearance position of fish schools at a predicted fishing time by referring to the living work and rest of the fished fish types in the formulating process; (2) alternative scheme: after the routes are formulated, collecting data of fish schools in surrounding zones of the routes, and fishing alternative fish schools in time when situations occur; and (3) material storage. According to the far-deep sea fishing method, in the using process, the position of the fished fish types can be better pre-judged through route making, the risk that fished fish schools cannot be found after going fishing on the sea is better reduced, according to the alternative scheme, the condition that the first-choice target fish schools cannot be fished when special situations occur after going fishing on the sea can be better avoided, the fished fish schools can be replaced in time, the situation that people go fishing on the sea with empty hands is avoided, and resource waste is reduced.

Description

technical field [0001] The invention relates to the technical field of fishing, in particular to a deep-sea fishing method. Background technique [0002] Fishing is the production activity of using fishing tools to catch economic aquatic animals. It is the most important part of the aquaculture industry. Generally speaking, there are three fishing methods: net fishing, hook fishing, hand catching, and using fishing tools to catch economic aquatic animals. Animal production activities are the most important part of the aquaculture industry. The international definition of the deep sea is the sea area with a water depth below 200 meters. The characteristics of the deep sea are: high pressure, slow bottom water flow, no light, low water temperature, high salinity, Oxygen content is abundant and sediments are abundant. [0003] Ocean fishing can be divided into coastal, offshore and pelagic (including open sea) operations. Coastal and offshore waters are rich in aquatic animal ...

AI Technical Summary

Problems solved by technology

[0003] Ocean fishing can be divided into coastal, offshore and pelagic (including open sea) operations. Coastal and offshore waters are rich in aquatic animal resources, and the unit catch is relatively high; ocean fishing is far away from the base, requires high fishing equipment and technology, and has low resource density. , the production cost is relatively high, but the fish with higher profit are all in the deep sea. Under the trend of profit, people will continue to go to the deep sea for fishing operations. When fishing in the deep sea, because it is far away from the base, it will affect the overall fishing cycle. There are more stringent requirements for resource preparation and resource preparation, and the danger is greater. With the danger comes huge profits, so many people will continue to engage in deep-sea fishing.

[0004] The existing deep-sea fishing methods do not have better fishing efficiency during the fishing process, nor do they have a more comprehensive guarantee for safety, nor do they improve the fishing efficiency during fishing, nor do they have a more systematic determination of fishing routes, and there is no Determine the fish species to be caught in advance to formulate the route, and the alternative plan is not perfect
