Abstract

The invention discloses a submarine automatic net casting fish trap which consists of a frame, a net bracket, a net pressing rack, bag-shaped fishnets, rubber float balls, liquid nitrogen gasification devices, rubber float ball controllers, a safety device, pumping bait devices, floating boxes, fishy boxes and automatic balancing pods; a plurality of rubber float balls are arranged around each bag-shaped fishnets; both sides of each rubber float ball are provided with rubber float ball controllers; the left side and the right side of the frame are provided with infrared lamps, pumping bait devices, floating boxes, liquid nitrogen gasification devices and batteries; the front side and the rear side of the frame are provided with a plurality of fishy boxes; the four corners of the frame areprovided with the automatic balancing pods; the frame is also provided with the safety device. The submarine automatic net casting fish trap is suitable to be operated in any bottom-layer sea area, applicable in capturing all fish on the bottom layer of the sea; the application of the novel capturing technology can develop novel farms in coral reef areas; the operation automation degree and the capturing capability are high, and the labor intensity and the energy consumption are low.

Description

technical field [0001] The invention relates to a marine fishery fishing machine, in particular to a seabed automatic net-casting fishing machine which is suitable for operation in any marine bottom environment, suitable for catching various fishes in the bottom of the ocean, and has a high degree of automation. Background technique [0002] At present, in the marine fishery industry at home and abroad, there is no fishing gear and fishing method to implement effective fishing for marine fishery resources in coral reef areas. There is still a blank in this technical field. There are four traditional fishing techniques in current fishing, and their technical characteristics are now described The advantages and disadvantages are as follows: [0003] Trawling technology: Trawling is divided into single-vessel trawl and double-vessel trawl, surface trawl and underwater trawl. The nets are dragged by fishing boats to accelerate forward in the ocean. Drag it into the bag to achie...
