Seine device for tidal flats and fishing method using the seine device

Abstract

The invention discloses an intertidal zone purse net device and a fishing method with the same. The intertidal zone purse net device is characterized by comprising a fishing net and a stand column, and the purse net device is provided with a lifting device capable of enabling the finishing net to ascend and descend. The intertidal zone purse net device has the advantages that fishes are not blocked by the fishing net when entering the purse net device along with tidal water and can smoothly enter the purse net device, the fishes in the purse net device are blocked by the fishing net, cannot escape when the tide is on the ebb and can only flow down along with the fishing net, and finally the fishes enter a cage-shaped net box; in this way, the fish collecting working time is saved, and the fishing yield is improved.

Description

technical field [0001] The invention relates to a purse purse net device for tidal flats and a fishing method using the purse purse net device. Background technique [0002] Our country is rich in tidal flat resources. It is common to use tidal flats for mariculture and tidal purse seine fishing. However, the tools and methods of purse seine fishing on tidal flats are relatively primitive. Generally, multiple bamboo poles are used as supports, and about 2 The meter-high net is unfolded and fixed on each bamboo pole, and each bamboo pole is inserted in an arc shape at a certain distance and can be withdrawn at low tide, and the seawater at high tide will be higher than the purse seine for rounding up, so that at high tide the seawater is high After passing through the seine, the fish will enter the seine from the top of the seine or from the place where there is no seine. When the tide recedes, the fish is blocked in the seine, and the fishermen push the beach boat to catch t...

[0002] Our country is rich in tidal flat resources. It is common to use tidal flats for mariculture and tidal purse seine fishing. However, the tools and methods of purse seine fishing on tidal flats are relatively primitive. Generally, multiple bamboo poles are used as supports, and about 2 The meter-high net is unfolded and fixed on each bamboo pole, and each bamboo pole is inserted in an arc shape at a certain distance and can be withdrawn at low tide, and the seawater at high tide will be higher than the purse seine for rounding up, so that at high tide the seawater is high After passing through the seine, the fish will enter the seine from the top of the seine or from the place where there is no seine. When the tide recedes, the fish is blocked in the seine, and the fishermen push the beach boat to catch the fish in the seine. This is the case every day, but because the rounding itself is about 2 meters high, in the early stage of high tide, the tide is not higher than the seine, and when the fish are most active, the fish move forward with the tide, but they cannot enter due to the block of the seine. When the tide is low, many fish will run away from the seine with the tide, and fishermen only catch fish during the day, and most of them give up at night, which greatly affects the fishing output.
