The invention belongs to the technical field of intelligent fishery and fishing, and discloses a saury fishing boat dynamic path planning method considering fishing point changes. Comprising the following steps: acquiring marine physical and biogeochemical data and a historical fishing data set, performing data cleaning, spatial alignment and normalization processing on the data, establishing a relation model between a fishing probability and a marine environment factor, constructing a dynamic fishing boat path planning problem model, and solving and outputting an optimal path. According to the method, accurate and green fishing of saury fishery is facilitated, the economic benefits and environmental sustainability of ocean fishery are improved, and powerful technical support is provided for high-quality development of modern fishery.

The utility model discloses a kind of needlefish stringing mould, including mutually buckled upper die and lower die, the upper die includes multiple fish body positioning parts and a fish head positioning part, multiple fish body positioning parts and fish head positioning part are arranged along the same linear direction interval, the lower die includes fish body positioning groove, fish head positioning groove and fish tail positioning groove, fish body positioning groove, fish head positioning groove and fish tail positioning groove are arranged along the same linear direction and mutually through, fish head positioning groove and fish tail positioning groove are arranged in the two sides of fish body positioning groove, the position of fish body positioning part corresponds with fish body positioning groove, the position of fish head positioning part corresponds with fish head positioning groove. The utility model is positioned to needlefish by mutually matched upper die and lower die, fish body does not displace when stringing, thus can ensure that stick accurately is worn into fish body, and the case where fish body is worn off or penetrated does not appear, and then improve stringing efficiency and the security of stringing.

The application discloses a kind of fast and efficient light trapping ocean bluefin horse mackerel fish gathering system and its using method, by designing light control scheme, the method for optimizing big light pole fish gathering lamp lens angle reduces the phenomenon that bluefin horse mackerel runs net when net is lifted, bluefin horse mackerel ship is divided into 3 regions, and long light pole and several lens angle changes LED fish gathering lamp are arranged at netting position;When fishing operation is carried out, all LED fish gathering lamps are opened for a period of time to complete fish gathering, and then LED fish gathering lamps on the bow, stern small light pole are sequentially closed from the middle of the left shipboard of fish taking part by control room switch according to closing order, and bluefin horse mackerel is gradually attracted to the position of big light pole above the net according to the closing order;At this time, several rows of fish gathering lamps on the big light pole are sequentially closed to the outermost side of the light pole.The application prevents fish school from swimming outward and appearing the phenomenon that net is run during net lifting process, improves the fish gathering effect and fishing efficiency of bluefin horse mackerel light fishing from details, and greatly improves the fishing yield and single fishing economic benefit.
