英文摘要 | The migration of the Black Pomfret in the Formosan Strait as reflected by their landings has been investigated. The data used in this report were drawn from the following sources: 1. Average yield per unit effort of seven years (from 1952~1958) obtained from 19 trawlers of the Chinese Fisheries Cooperation. 2. The total landing obtained by off shore and coastal fishing gears from the South-West of Taiwan in 1962. From the above data the following items were derived. The monthly weighted mean, standard deviations, medians, skewness and addition of vectors of the yield; centers of fishing grounds; the main fishing area; the centers of the fish schools; the trend of movement. According to the above calculations, it is postulate that the Black pomfrets migrated from south to north and vise versa in the Formosan Strait. The fish migrated northward from March, and southward from August to November. There seemed to be two types of migration. Type I: the fish migrated northward to a shorter distance and returned earlier to the south near Kaoshiung. Type II: the fish migrated to further north, returned later in the year and only reached Pescadores Islands. |
