碩士 / 國立臺灣海洋大學 / 環境生物與漁業科學學系 / 107 / The goldlined seabream (Rhabdosargus sarba) is a common species caught by the Taiwanese coastal fisheries. However, its biological information on spawning ground, migration route, reproductive biology, and age and growth is little known. In total, 593 specimens ranged from 12.3 to 44.0 cm in total length (TL) and 28.9 to 1832.0 g in body weight (BW) were collected from the coastal waters off Penghu from September 2015 to August 2016. The maximum likelihood ratio test indicated the sex-specific relationship between body weight and length is not significantly different and can be expressed as: BW= 0.01511 TL3.0346 (r2= 0.950; n= 593). The edge analysis indicated the growth rings on otolith were formed once per year, and the opaque zones were deposited in December. Age estimate was made by counting opaque zones in sagittal otolith sections of 447 specimens under transmitted light. Three growth functions namely the VBGF, the Robertson and the Gompertz function were used in this study. Based on AICc and w_i, VBGF was chosen to be the best growth function for R. sarba. The maximum likelihood ratio test indicated that no significant difference on growth between females and males and the parameters of VBGF for R. sarba (sexes combined) were L∞=53.94 cm TL, k=0.217 year-1, t0=-0.182 year. The oldest ages were 8.17 and 8.00 years old for females and males, respectively.
