| 内容記述 | Various selective fishing gears have been used for coastal trawls in Japan. Coastal fishers in Soma-Haragama area developed a selective trawl net by themselves which has been in use for more than 20 years. A survey on the construction of this selective trawl net and follow-up experiments using a scale model net suggested that the actual mechanism for separating components of the catch was different from that hypothesized by fishers. A partition net with large mesh is attached in two places in the cod-end that separates the cod end into three chambers where selection can take place. The primary design characteristic of the partition net is that it is attached to the upper and lower net body at its fore and aft ends with lateral edges hanging free. In this manner, the fishermen hypothesized that separation occurs when garbage and fish encounter the obliquely angled netting panel and either pass through or are guided to another part of the cod end. In an experiment using a 1:10 scale model net, to observe the separation function of this net. It was observed that the partition net did not form a plane panel but rather created a netting pocket on the side of a bottom net. The garbage were separated from the fish, where they accumulated in this pocket formed by the partition. | |||||||||
