摘要: Large yellow croaker Larimichthys crocea (LYC) is the most cultured marine fish species in China. We described growth characteristics of cage-cultured LYC from three typical culture districts: Jiaocheng (JC), Shacheng (SC) and Xiapu (XP) Fujian Province, ANOVA revealed significant differences average body length weight among areas (P < 0.01), with Duncan’s multiple range test indicating fishes XP had best grow performance. Length-weight relationships for JC, SC were: W=2.39 × 10⁻⁵×L².⁹⁹, W=2.22 × 10⁻⁵×L².⁹⁶, W=1.94 × 10⁻⁵×L².⁹⁸, respectively. All groups isometric growth, having highest asymptotic L∞ (34.9 cm), followed by (33.5 cm) JC (27.8 cm). Trends (W∞) were similar, values XP, being 748.3 g, 651.0 g 484.4 g, Inflexion points occurred at 12, 17 18 months age SC, A negative correlation was apparent between fatness water temperature (r = - 0.54, P < 0.05). stock faster a smaller size within an aquaculture environment compared to wild stock.
