阿根廷魷漁業資源量與環境因子變異之研究

年度 2006
計劃名稱 阿根廷魷漁業資源量與環境因子變異之研究
中文摘要 本研究探討西南大西洋阿根廷魷的資源量年變化與位於Rio de la Plata河口附近孵育場上環境變異之相關性。以中民國對外漁業合作發展協會和福克蘭群島政府漁業部和所公佈的漁獲統計資料計算阿根廷魷CPUE作為阿根廷魷資源量年變化的指標,並以西南大西洋陸棚上SeaWiFS葉綠素a濃度和SST資料作為孵育場上環境變異的指標。分析結果顯示阿根廷魷CPUE的年變化與漁季前Rio de la Plata河口南方陸棚上八月的葉綠素a濃度以及五月的SST成正相關。
英文摘要 In this study, the influences of environmental variability over the shelf off Rio de la Plata on abundance of Illex argentinus in the Southwest Atlantic is investigated. Statistics published by Overseas Fisheries Development Council of the Republic of China and Falkland Islands Government Fishery Department on Illex argentinus were used to calculate CPUE as a measure of squid abundance. SST and chlorophyll a concentration derived from SeaWiFS images over the shelf off river estuary were used as environmental indices. It was found that squid CPUE is positively related to SST and chlorophyll a concentration over the shelf south of Rio de la Plata estuary from May and August prior to the fishing season respectively.
