| Abstract: | Trichiurus haumela is one of the major commercial fish populations in the Beibu Gulf of the northwestern South China Sea. It is of great significance to estimate population parameters and assess the stock status of T. haumela for the fishery management in the Beibu Gulf. Based on the biological data of T. haumela collected in the Beibu Gulf from 2006 to 2016, the asymptotic length (Linf), the optimal length-at-first-capture (Lc_opt), relative mortality (M/k and F/k), exploitation rate (E), and relative biomass (B/B0) are estimated using the length-based Bayesian biomass estimation method (LBB). The results show that the Linf is 44.4 cm, the mean of Lc_opt is 28.5 cm, the mean of M/k and F/k are 1.32 and 2.76, the F/M is 2.20 and the E and B/B0 are 0.67 and 0.16, respectively. The anal length of the first gonadal maturation (L50%) is 28.63 cm fitted by Logistic models. The results show that the current stock of T. haumela in the Beibu Gulf is over-exploited, the extant biomass is relatively low, the length-frequency tendes to simplification and miniaturization. |
