中文摘要 | 本文係以鱗片為年齡形質,研究臺灣東北部蘇澳沿海之�[�隤漲~齡與成長。 使用標本計有220尾為1983年12月至1985年3月於南方澳漁港的底拖網漁獲者,本 種每年形成二個輪,分別在二月和七月。雌雄別間之反推尾叉長並無顯著差異 。利用Walford定差圖法求得von Bertalanffy成長曲線之參數分別為:極限尾叉長 (L∞)=63.3cm,成長係數(K)=0.087,尾叉長為零之年齡(t0)=-1.213年。 |
英文摘要 | Age and growth of the white-tongued crevalle, Uraspis helvolus, caught by commercial bottom trawlers in Suao coastal waters of northeastern Taiwan from December 1983 to March 1985 were studied from the annulus counts on the scales of 220 individuals. The growth resting zones in the scales were formed twice a year, in February and July, respectively. The back-calculated fork length has no significant difference between female and male fish. The parameters of von Bertalanffy growth equation setimated by the Ford- walford method were as follows:asymptotic length (L ∞ )=63.3cm in fork length, grow coefficient (k)=0.087,age at zero length (t0)=-1.213yr. |
