本報告係利用最大相似法(maximum likelihood method)將澳洲西北陸棚產金線魚之體長組成轉換成年齡組成,並估計其生殘率及全死亡係數。 結果顯示:(1)以有大相似法可將金線魚之體長組成精確的轉換成年齡組成,並且依年齡組成估算所得之體長頻度分佈與實測之體長頻度分佈極為一致。(2)近年來金線魚各市場規格別之體長頻度分佈變動不大。(3)澳洲西北陸棚產金線魚被漁獲的主要年齡組為2~5歲。(4)在目前之漁業型態下,本海域本種魚的完全加入羣為3歲魚。(5)1984年至1986年本種魚的瞬間全死亡係數分別為0.9029、0.9002及0.9064。
This paper deals with the survivals of golden thread (Nemipterus peronii) resource in the northwest shelf of Australia based on size frequency data obtained from surveys at Kaohsiung Fishing Port. Conversion of age distribution from size frequency data by using maximum likelihood estimate criterion is adopted. The results show that (1) age composition can be reasonably derived from a length frequency data by using maximum likelihood estimate criterion, and the fitting between the observed and the calculated frequencies has been very successful; (2) there is no significant difference in length frequency of market size categories in recent years; (3) age Ⅱ to age Ⅳ are the main age groups in N. peronii catches harvested from the northwestern shelf of Australia; (4) fully recruited age of the resource appears to be age Ⅲ; (5) the yearly total instantaneous mortality rate (Z) of the resource was estimated as: 0.9029, 0.9002, and 0.9064 for the years from 1984 to 1986, accordingly.
