Automatic cage catching (fishing) machine at ocean floor

Abstract

The invention discloses a submarine automatic cage fish trap which consists of a removable fish cage, a liquid nitrogen gasification device, a safety device, a floating box, an automatic balancing pod, a device used to increase the flowing speed in the fish cage, a feeding bait device, a fishy box, a gate controller and a monitor. Wherein, the gate controller consists of a switch fishing warehouse gate, a device used to drive the fish into a fish storage house and a switch fish storage house gate. The fish trap has the advantages that the fish trap can enter into coral reef areas that the prior top four fishing tackles and fishing methods cannot enter into to trap fish and develop fishery resources; the operation of the fish trap does not bring damages to the marine ecological system; the fish trap can trap all submarine fish and crabs in the daytime, all shrimps and lobsters in the nighttime, and squid in the nighttime under the light of lamps, add the trappable shark of a blood bank, and is a comprehensive and multi-functional trapping device which has the advantages of high trapping capability and automation degree, low operation labor intensity, high efficiency, high yield and lower energy consumption.

Description

technical field [0001] The invention relates to a marine fishery fishing machine, in particular to a seabed automatic cage fishing (fishing) machine for fishing various fishes, shrimps and crabs at the bottom of the ocean, with extremely strong fishing ability and high degree of automation. Background technique [0002] At present, fishermen seldom use fish cages for fishing operations. Because the structure of the fish cage is too simple, there are no other effective measures to prevent the fish from wandering outside the cage. There is no way for the fish to enter, so the fishing range is very limited. Because the fish cage lacks the fish luring function device, it is impossible to attract the attention of the fish school. It can be seen that the trapping ability is low, and it is a passive fishing gear fishing method. At present, the entrance of the fish cage is fixed vertically. When the fish cage is placed on the seabed, the seabed is not horizontal, so the entrance can...

Problems solved by technology

[0002]At present, fishermen seldom use fish cages for fishing operations. Because the structure of fish cages is too simple, there are no other effective measures to prevent fish from wandering outside the cages. To solve this difficulty Generally, the entrance of the fish cage is set very narrow, and larger fish cannot enter if the entrance is narrow, so the fishing range is very limited. Because the fish cage lacks a fish luring function device, it is impossible to attract the attention of the fish school. It can be seen that Low trapping capacity, is a passive fishing gear method

At present, the entrance of the fish cage is fixed and vertical. When the fish cage is placed on the seabed, the
