碩士 / 國立臺灣大學 / 海洋研究所 / 98 / Age and growth of striped marlin in waters off Taiwan were examined based on counts of annual growth rings on cross sections of the fourth spine of the first dorsal fin. In total, 1,416 length samples of striped marlin were collected from November 2004 to April 2010, of which 731 were males , 558 were females, and 128 were sex unknown. The length-weight relationships between sexes were combined (W = 5 × 10-6 EFL3.15) because of no significant difference (P > 0.05). There were 241 (of 291, 83%) spines for males and 206 (of 226, 91%) for females aged successfully. The time of the formation of the first ring was validated by reading the daily rings on the cross section of the otolith of striped marlin. The APE (average percent error) is 8.96 and 7.61% and the CV (coefficient of variation) is 11.80 and 11.54% for male and female striped marlin respectively. The analysis of MIR (marginal increment ratio) suggested that the growth bands of striped marlin formed once a year (during October to next January). The back-calculated lengths for each age were computed using the Fraser-Lee''s and Monastyrsky methods, and then used to fit the standard and generalized von Bertalanffy growth equations (VBGEs). Results showed that the fits to generalized VBGE were better (based on AIC statistics) than those for standardized VBGE. The estimated growth equations for male and female striped marlin were not statistically different through the analysis of residual sum of squares (ARSS, P > 0.05). The sex-combined generalized VBGE of striped marlin is estimated as follows:Lt=277.4(1-e-0.17(1-0.73)(t-0.22))(1/1-0.73).
