Dead fish fishing device for aquaculture

Abstract

The dead fish fishing device comprises a main rod and a net frame, a grab handle is arranged at the bottom of the main rod, an adjustable inner rod is arranged above the main rod, a top block is arranged at the head of the inner rod, a dip net is arranged on the inner ring of the net frame, and a connecting block is arranged at the bottom of the outer ring of the net frame. The lower end face of the connecting block is provided with an outer frame plate, and the lower end face of the outer frame plate is provided with a mounting groove corresponding to the top block. The dead fish salvaging device for aquaculture belongs to the field of aquaculture, the length of the salvaging device is conveniently adjusted by arranging an inner rod capable of being telescopically adjusted above a main rod, a top block is arranged at the head of the inner rod, a connecting block and an outer frame plate are arranged below a net frame, and the top block is matched with the outer frame plate for installation and fixation; meanwhile, the pressure block is used for quick disassembly, the net frame and the dip net of the corresponding specification can be conveniently and quickly replaced according to different aquatic products, and dead fishes can be fished more conveniently.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a dead fish salvage device for aquaculture. Background technique [0002] Aquaculture refers to the cultivation of fish or all kinds of seafood for food in the artificial fishing grounds on the shore. The southwest coast is the most densely distributed, and the cultivation of milkfish, oysters and eels is common. Since some aquatic organisms will die during the cultivation process and float to the water surface, it is necessary to clean up the dead fish floating on the water surface in time. Usually, farmers use It is difficult to adjust the length of the net copying tool for salvage with the fixed structure of the net copying tool. At the same time, due to the fixed structure of the net copying tool, it is also difficult to replace the net copying head, which is more inconvenient when salvaging fish of different sizes and types. The dense net is easy to stick to the algae, and it is ...

AI Technical Summary

Problems solved by technology

[0002] Aquaculture refers to the cultivation of fish or various seafood for consumption in artificially opened fishing ponds on the shore. According to the different water quality of aquaculture, it can be divided into three categories: freshwater aquaculture, saltwater aquaculture and sea surface aquaculture. The southwestern coast is the most densely distributed, and milkfish, oysters, and eels are commonly cultured. Since aquatic organisms will die during the breeding process and float to the water surface, it is necessary to clean up the dead fish floating on the water surface in time. Usually, farmers use It is difficult to adjust the length of the net-dipping tool for fishing with a fixed-structure net-dipping tool. At the same time, due to the fixed structure of the net-dipping tool, it is also difficult to replace the net at the head. It is inconvenient when fishing for different sizes and different types of fish. Dense nets are easy to stick to algae, and are also prone to breakage due to the pressure of large fish. Sparse nets may cause small aquatic species to be missed, causing inconvenience
