一份最新的研究顯示,商業漁業所帶來的威脅,不僅是減少目標魚群的存餘總量。研究者們發現,由於商業漁業企圖撈捕較成年、力壯的大魚,所剩年輕且體型較小的魚群,較缺乏在變動中的生態系統中存活的能力,使得整個族群陷入莫大的生存危機。
Study Urges Protections of Big Fish
Commercial fishing does not just threaten targeted stocks by reducing the overall number of remaining fish, according to a new study. Researchers have found that commercial fishing puts populations at greater risk of collapse because it tends to remove older, stronger, bigger fish, leaving behind younger, smaller fish less capable of surviving natural changes in the ecosystem.
