  • 초록

    Stow-net is originally spreaded with a lifting beam and a depressing beam. The net is improved by using canvas-made spreading devices by Mr. Han and his colleagues in the beginning of 1980's. The net is improved again by changing the partial shape of netting and arrangement of net pendants so as to be fitting with the actual performance of the net by Dr. Lee and his colleagues since 1988. The author studied to compare the fishing efficiency of those two kinds of nets(The former which was improve by Mr. Han is expressed as a traditional net and the latter improved again by Dr. Lee is expressed as an improved net in the present study). Twenty-one stow-netters concerned with the present study were selected among those based on the Port of Inchon, and were classified into two groups-eleven of them are a traditional net used group and ten are an improved net used group. The data on the fishing operation from August 1992 to March 1993, including the catch, the price of sell, the fishing operated times in every cruise and the fished position noticed by every stow-netter were offered by concerned stow-netters. From the data the times of operation, catch and value in every cruise were extracted and analyzed. The results obtained can be summarized as follows: 1. The times of operation in cruise were 13.7 by the traditional net used group and 12.7 by the improved net used group. 2. The mean catch per cruise showed 10.1M/T in the traditional net used group and 12.2M/T in the improved net used group, so the latter showed 21% better. 3. The mean catch per operation showed 0.7M/T in the traditional net used group and 0.9M/T in the improved net used group, so the latter showed 28% better. 4. The rate of three important species(starks, hair tail and croakers) in the total catch showed 83%, and the catch showed greater by the improved net used group at the rate of starks 141%, hair tail 110%, croakers 107%. 5. The rate of three important species in the total price showed 82%, but the price of starks which occupied the biggest in catch showed merely 5%, then the economical efficiency appeared low. 6. The mean price per stow-netter and per operation showed about 20%, greater respectively by the improved net used group and the mean price per operation by two important species(hair tail and croakers) showed greater about 30% by the improved net used group.
