タイのプッシュネットにより漁獲された屑魚と投棄生物 Trash Fish and Discards of Push Net Catch in Thailand 城本, 朋美 101675 Shiromoto, Tomomi バンデット, チョケサンガン 101676 Bundit, Chokesanguan 井上, 喜洋 101677 Inoue, Yoshihiro 660 自然科学 trash fish discard push net bycatch Thailand This investigation focused on trash fish and discards in push nets operated by local fishermen twice during day time at Samuut Prakan Province in Thailand. The push net catch was divided into three categories: commercial fish, trash fish and discards. Total weight of the catch, and body length and weight of the species were measured in each category. A survey of fishing gears and methods was carried out by interviewing fishermen. The catch was divided into discards (54% of total weight ), commercial fish (23 %) and trash fish (23 %). Almost 80% of the discards were crabs, Charybdis affinis, while soapy, Leiognathus sp. accounted for 69% of trash fish. In trash fish and discards, juveniles of commercial species were included, while almost all of soapy in trash fish were adults on their mean length. The discards ratio ( = discards /landing) was 1.17, and discard rate [ = discards / ( landing + discards ) ] was 0.54. departmental bulletin paper 鹿児島大学 Kagoshima University 2006-12-25 VoR application/pdf 鹿児島大学水産学部紀要 55 43 50 Memoirs of Faculty of Fisheries Kagoshima University 0453087X AN00040498 https://ir.kagoshima-u.ac.jp/record/3420/files/55-5-siromoto.pdf http://hdl.handle.net/10232/1407 https://ir.kagoshima-u.ac.jp/records/3420 jpn open access
