Embodiment

[0020] Example: time and place: at 2:00 am on August 14, 2011, the water temperature was 25°C, and the place was located in the coastal waters of Xingken Town, Qidong City, Jiangsu Province.

[0021] Net gear: Insertion net 1 is 1.2m high, mesh is 1cm, the distance between inserting net stakes is 4m, and the width of the net port of pushing net 2 is 2m.

[0022] Fishing operation: When the water level near the shore where the net is inserted drops to 50cm at low tide, use the push net to carry out push net fishing near the place where the net is inserted. Each operation lasts for 2 minutes to lift the net. The squamous four-fingered horsefin juveniles caught in the net bag at the bottom of the net are quickly picked up and quickly thrown into the transport tank pre-filled with clean seawater taken from the water area where the net is inserted and continuously inflated

[0023] Fishing effect: 420 juvenile Spanish finfish with scales were caught in the tide water, including 398...

Abstract

The invention relates to a method for fishing juvenile eleutheronemate rhadinum living bodies, which comprises the following steps of: laying an inserted net in a coastwise water area at the water depth of 1.5 to 3m on a high water level during flood tide; waiting for the flood tide, so that juvenile eleutheronemate rhadinum enters a nearshore water area of the inserted net, and the juvenile eleutheronemate rhadinum is stopped in the net area by the inserted net during falling tide; and pushing the inserted net on a nearshore side of the inserted net by using a push net when a falling tide water level is reduced to a water depth of 50cm in the nearshore water area of the inserted net, fishing the juvenile eleutheronemate rhadinum blocked in the inserted net, lifting the push net out of the water surface, keeping the bottom of the tuck net soaked in water, rapidly fishing the juvenile eleutheronemate rhadinum captured at the bottom of the tuck net of the push net by using a fishing net, and rapidly throwing the juvenile eleutheronemate rhadinum into a transportation water tank in which clean seawater which is taken from the water area of the inserted net and is continuously aerated is filled in advance. By the method, the problem of high death rate in the process of fishing the juvenile eleutheronemate rhadinum can be solved.

Description

technical field [0001] The invention relates to a fish fishing method, in particular to a live fishing method for multi-scale four-fingered horsefin juveniles. Background technique [0002] Eleutheronemate rhadinum (Eleutheronemate rhadinum), also known as Mayou, Wuyu, and Zhangtiao, is a marine economic fish widely distributed in the southeast coast of my country. It has the advantages of fast growth, wide adaptability, and high economic value. It is a famous and precious species in seawater fish, and is very popular in Jiangsu, Zhejiang, Fujian, Guangdong, Taiwan and Hong Kong. However, the natural resources of the multi-scaled four-fingered horsefin are few. Under the situation that the natural resources cannot meet the market demand, it is an urgent technical problem to carry out the artificial breeding and breeding technology of the multi-scaled four-fingered horsefin. [0003] In the process of fish breeding, breeding, and breeding research, it is an indispensable and ...
