Present study aimed to be increased productivity and technique level of fishermen by education for the design criteria of the improved East-sea trawl net and seine net catched shrimps and the coastal fishes in the deep sea of about 300∼600m depth, and to be decreased cost of operation by development
Present study aimed to be increased productivity and technique level of fishermen by education for the design criteria of the improved East-sea trawl net and seine net catched shrimps and the coastal fishes in the deep sea of about 300∼600m depth, and to be decreased cost of operation by development for the operating system with laborsaving technical machines.
A series of study for the East-sea trawl net and seine net was carried out to be achieved purpose of present study.
As the first step of these studies, we investigated the present condition of the East-sea trawls and seine nets to be established the developed contents of both fisheries. That is, the fishing gear and system of the traditional East-sea trawl were checked in order to solve the some problems, such as the poor sheering efficiency of net mouth, the inconvenient fishing system of the side trawl and etc. And then, the fishing system was reorganized from the side trawl into the stern trawl by setting up the net drum system on the stern deck, and introduction of two types of new designed nets, one for mainly the mid water trawl and the other for the bottom trawl.
As the second step, we designed and manufactured the improved net and laborsaving operating system, based on the condition of fishing ground, fishing vessel, fisherman's skill and fish behavior. And, we carried out the field experiment for gear-structure, productivity and fishing efficiency of the improved trawl net to be of practical use, and made the model of laborsaving technical operating system.
Also, we carried out study on the fish handling system, that is the transfer system and the vessel's fish processing system, and attempt to be established the new circulating model of the new commodity with small size.
The obtained results can be summarized as follows:
1. Study on the East-sea trawl fishery
The laborsaving operating system by setting up the net drum system was well worked and could save the man-labour by about80%The sheering efficiency of the improved net with 1,620mm of maximum mesh size, A type was shown to 20m height and 30m width in the net mouth, and that of B type net, to 10m height and 33m width, compared with 1.5m height and 15m width in the traditional net.
Catch efficiency pink shrimp was better about 3 or 5 times in A or B type net than that of traditional net, and in B net, for herring and other bottom fishes was better about 2 times than that of the traditional net, for flatfish was better about 1.5 times than that of the traditional net. And, the improved trawl net was little catched conch and crab, that is, this net was greatly increased catch selectivity
2. Study on the seine fishery.
The laborsaving operating system by setting up the hand rope winch drum system was well worked and could save the man-labour and operating time by about 80%The sheering efficiency of the improved net was shown to about 10m height at towing speed of 0.5∼1.0 knot, to about 8.0m height at1.5∼2.0 knot, compared with 8.0m height at 0.5∼1.0 knot, to about 6.5m height at 1.5∼2.0 knot in the traditional net.
Catch efficiency of flatfish is better about 1.1∼1.2 times than that of the traditional net
3. Study on the fish handling system.
The fish transfer system by setting up the horizontal and lift conveyer system was well worked in the practical use and could save the man-labour and operating time by about 70%. And, the vessel's fish processing system by setting refrigerator, steamed device and packing device was well worked, and thawing frozen pink shrimp was nice tasty same as fresh shrimp could eaten raw. A frozen pink shrimp in small case was well preserved during about 2 months in a small case covered poly-vinyllab
4. The economic analysis
Annual catch amount of the East-sea trawl with the improved trawl net was increased about 500 million won in 2,000 year, compared with about 300 million won in 1,999 year. And, annual catch amount of the improved trawl net can be expected about 600million won with increasing about 2.0 times than that of the traditional net in 2,002 year.
Fishing efficiency of the improved seine net operated with the laborsaving operating system was expected about 350∼400 million won with increasing about 1.2 times than that of the traditional net.
