英文摘要 | The study was conducted at Mang-fong, southwestern Taiwan between March and June, 1997. Behaviours of fish school moving to and from the bagnet and toward the funnel net were monitored by telesounder, which was positioned at top of the funnel of an otoshi-ami setnet. About 65% of fish caught entered and stayed in the net during the evening. Giant trevally Caranx ignobilis evidently swam actively towards and entered the funnel during the nocturnal period. This implys that they are caught during the morning. Round frigate mackerel Auxis tapeinosoma contradictorily were active in the daytime and entered the funnel during the afternon. Most fishes swam through the funnel net at a depth of 5-20 meters. The evening-active fishes often swam closer to the surface than the daytime-active fishes. |
