Description

A kind of fishing net applied to cultured fish rafts and its use method

The present invention relates to a fishing net, in particular to a fishing net used in farming fish rafts.

The present invention also relates to a method of using the above-mentioned fishing net.

Traditionally cultured fishing rafts are mostly set up on the offshore surface, and use cages made of wood or rubber to cultivate seafood, such as various fish, shrimps, abalone, sea cucumbers, etc. This can increase the income of fishermen and the cost of investment is also relatively low. Farming in ponds on land is low-cost, but traditional wooden fishing rafts will cause environmental problems. In order to expand the breeding area, some farmers will build fishing raft bases on the waterway, which will seriously affect the passage of ships.

In addition, the government implements the planning and layout of marine aquaculture prohibited areas, restricted areas, and breeding areas. For this reason, the use of aquaculture fish rafts must not only consider costs, but also comply with government policies. For this reason, how to operate in restricted areas Achieving better economic benefits within a certain period of time has become an important issue for farmers.

The fishing net used in farming fishing rafts as described in claim 1 or 6, further has a rope-pulling mechanism connected to the upper edge net rope and the lower edge net rope. The fishing net used for farming fishing rafts as described in claim 1 or 6, wherein the upper edge net rope is directly connected to the upper edge weight, and the lower edge net rope is directly connected to the lower edge weight. A method of using a fishing net applied to aquaculture fishing rafts, including: The first step of luring fish is to release an upper edge net rope so that a movable upper edge section can be moved along the upper edge by an upper edge weight. Approaching a movable lower edge section in a direction A to create an opening to form a fish luring state; In the step of closing the net, a force opposite to the A direction is applied to the upper edge net rope to make the movable upper net rope The edge segment moves away from the movable lower edge segment along the direction opposite to the A direction to close the opening and form a net closing state. The method of using a fishing net applied to aquaculture fishing rafts as described in claim 19, wherein there is also a fishing step of applying a force opposite to the A direction to the lower edge of the net rope to provide the movable lower edge section along the On the contrary, it approaches the movable upper edge in the direction A to form a fishing state.
