臺灣週邊海域眼眶魚 ( Mene maculata)為扒網漁業中重要魚種之一,但近 5年來漁獲量大幅減少,實有必要對眼眶魚漁業之近況進行調查與瞭解。本計畫將針 對臺灣週邊海域眼眶魚生殖生物學、漁獲量及漁船作業位置等資料蒐集,調查漁場 及漁獲重心,以掌握作業動態進而提出管理建議。本年度將會持續收集體長資料 ,未來希望藉由比較今昔眼眶魚生活參數如成長速率、極限體長及生殖期等變化 ,來探討過去20多年,漁獲壓力對於臺灣週邊海域眼眶魚之影響。
研究報告摘要(英)
Mene maculata is one of the most crucial fish species caught using Danish seine in the waters around Taiwan. At the time of writing, the catch volume of the species had substantially decreased for five consecutive years, which warranted the investigation into the current situation of M. maculata fishing. This project aimed to collect data on the reproductive biology of M. maculata in the waters around Taiwan, the catch volume of the species, and fishing boat operating positions and to survey fishing grounds and the focus of fish catch, thereby understanding the operating dynamics of M. maculata fishing and proposing management suggestions.we will continue to collect data on the body length of orbital fish. In the future, By comparing previous and current life parameters of M. maculata, such as growth rate, maximum body length, and reproductive period, this study explored the effect of fishing pressure on M. maculata in the waters around Taiwan in the past two decades.
