碩士 / 國立海洋大學 / 漁業學系 / 81 / The black croaker ~u2;Atrobucca~u1; ~u2;nibe~u1; of 758
specimens , caught by small trawler and bottom longline in
Tungkang waters from April 1986 to May 1987, were determining
age and growth from otolith annuli. Opaque annuli were formed
in otolith once per year during May to July. The oldest fish
found in this study were 8 yrs for female and 7 yrs for male,
respectively. There are significant differences in the
relationship of total length (TL) and otolith radius (R). These
are: TL=79.410R-110.225 (TL:mm; R:mm) for female and TL=77.143
R-104.071 for male. The von Bertalanffy growth equations are
estimated as: Lt=533.84{1-exp[-0.183(t+0.316)]} (mm) for female
and Lt=525.77{1-exp[-0.187(t+0.214)]} for male. The
relationship between body weight (W) and total length for both
sexes, fitted by allometric growth equation, are W=1.208*10-5*
L^2.968 (W:g; L:mm) for female and W=1.374*10^-5L^2.936 for
male. The von Bertalanffy growth equations expressed in weight
are : Wt=1500.97 {1-exp[-0.183(t+0.316)]}^2.968 (g) for female
and Wt = 1333.55 {1-exp[-0.187(t+0.214)]}^2.936 for male.
