利用1992年2至7月間,連續6個月之月別體長頻度資料及ELEFAN之方法,來估計台中港附近海域產劍蝦(Parapenaeopsis hardwickii)之季節性成長參數、死亡率及加入型態。本研究中只使用雌蝦之體長頻度資料加以分析。應用體長頻度分佈擬合季節性本托蘭裴成長方程式(von Bertalanffy growth equation),其結果如下:極限頭胸甲長L=39.0mm,成長參數K=1.1(1/year),C=0.95 and WP=0.94。利用季節化體長轉換漁獲量曲線估計其全死亡係數Z為6.37(1/year)。利用兩種經驗式,估計其平均之自然死亡係數M為2.07(1/year);漁獲死亡係數F利用Z=F+M之關係式求得為4.30(1/year)。開發率E為0.67(F/Z),顯示本蝦種已有過度開發之情形。加入型態分析結果顯示,劍蝦每年具有兩個強度不等之加入群。劍蝦之最大年齡估計為2.74年。
Seasonal growth parameters,mortality rates and recruitment pattern of female swordprawn(Parapenaeopsis hardwickii)were estimated from a length-frequency data set withELEFAN methods.The 6-month data set was collected from the adjacent waters offTaichung harbor between February and July 1992.Parameters of the von Bertalanffygrowth equation with seasonal fluctuations obtained were:L(subscipt ∞)= 39.0 mm carapace length,K=1.1(1/year),C=0.95 and WP=0.94 of year.The total mortality coefficient Z was6.37(1/year)estimated by seasonalized length-converted catch curve procedure.Theaverage natural mortality coefficient M of 2.07(1/year)was obtained from the empiricalmethods of Pauly(1980)and Srinath(1991).The fishing mortality coefficient F was 4.30(1/year)(F=Z-M).The exploited rate E of 0.67(F/Z)showed that the sword prawnpopulation is over-exploited.The annual recruitment pattern obtained by back-projectingthese length frequency samples onto an arbitrary one-year time axis showed that recruitmentsoccur in two pulses of unequal strength.The longevity t(subscript max)of sword prawn is 2.74years.
