Wild acanthopagrus latus fry fishing device and wild acanthopagrus latus fry fishing and transporting method

Abstract

The invention relates to the technical field of fishing devices, in particular to a wild acanthopagrus latus fry fishing device and a wild acanthopagrus latus fry fishing and transporting method. The wild acanthopagrus latus fry fishing device comprises a fishing device body and a fish collecting device which are connected. When wild acanthopagrus latus fry is fished and transported by means of the method, the fishing yield is high, the labor cost is low, the method is ecologically friendly without damaging other organisms, no bad influence on the marine environment and ecology is generated, and the fry survival rate can be improved to the utmost extent at the same time. The device and method are suitable for fishing production and investigation and beneficial to normalized and standardized operation of fry and juvenile fish resource investigation, and reduce the phenomenon that wild fry resources are wasted caused by mass mortality in the natural fishing process, and a substantial technical support is provided for resource evaluation, sustainable utilization and the like of the wild fry.

Description

technical field [0001] The invention relates to the technical field of fishing devices, more specifically, to a fishing device for yellowfin roughy natural fry and a method for fishing and transporting the same. Background technique [0002] Yellowfin seabream, also known as yellowfin seabream, belongs to Perciformes, Seabreamidae, and Seabream genus. Commonly known as yellow wall, yellow foot stand, red wing, etc., it is widely distributed in the southeast coast of my country and is a common warm-water bottom fish in shallow seas. , its meat is fresh and tender, and it is rich in nutrition. It is deeply loved by consumers and is an important marine economic fish. In recent years, it has become one of the important species in the proliferation and release of fishery resources in the South China Sea. Therefore, there is an increasingly strong demand for yellowfin roughy fry in mariculture, multiplication and release. [0003] The fishing of natural fry has a long history in o...

Problems solved by technology

[0006] The main problem of this method: the catch of fish fry is very limited, and the labor cost is high (time-consuming and labor-intensive)

[0008] The main problem of this method: Although the efficiency is much higher than that of traditional manual fishing, the trawling net makes the fish fry densely concentrated in the mesh bag, which is very easy to squeeze and collide with each other and cause mechanical damage, which reduces the survival rate of fish fry

The current problem is that there is a lack of a systematic guidance method, including the entire process from the natural fry fishing of yellowfin roughy to the pond (or into the cage) to start the culture process
