“…This might be due to the long interval (about 20 years) before data comparing with the present study data (2017)(2018)(2019). For the U. sulphureus, our results corresponded with other research findings [36], where yield-per recruit analysis was used to assess the stock in this area, which indicated overfishing (Table 3). These results are more similar to the findings obtained by [31], where they also found overfishing conditions.…”

“…Most of the findings of other species from various reports were consistent with the current study, with some exceptions in the case of I. filigera and S. tumbil, that there was overfishing of the fishery resources in this area. Yield-per recruit analysis Over exploited [36] The finding of grossly overfished for L. savala was confirmed by the results of [31,32], where they found that the species was overfished based on survey data such as the present study (Table 3). However, the finding of not overfished conditions from [33] study might be due to the use of different meshed gear landing data in their analysis.…”

Stock Assessment for Seven Fish Species Using the LBB Method from the Northeastern Tip of the Bay of Bengal, Bangladesh

Assessment of fish stock status is generally required for fisheries management, which is difficult when the data are limited. The length-based Bayesian Biomass (LBB) approach is a powerful and new method, where only the length-frequency data are used for estimating the status of fisheries resources. Here, we applied the LBB method to assess the status of seven commercially valuable marine fishes from the northern tip of the Bay of Bengal (BoB), Bangladesh. These species were Lepturacanthus savala, Pampus argenteus, Nemipterus japonicas, Nemipterus randalli, Ilisha filigera, Saurida tumbil, and Upeneus sulphurous. The current relative biomass (B/B0) ratios were smaller than the BMSY/B0 in five stocks, except for N. japonicas and N. randalli, and this indicates that, of the seven populations assessed, two are grossly overfished, three are overfished, and two are healthy stocks. Moreover, the length at first capture (Lc) was lower than the optimal length at first capture (Lc_opt) in all seven populations, which indicates growth overfishing, suggesting that increasing the mesh sizes would be beneficial. The present findings confirm that Bangladesh’s coastal water fishery resources are declining. More specific targeted management measures should be taken to recover the country’s marine fishery resources.

Population dynamics parameters and stock status of Squaliobarbus curriculus (Richardson, 1846) were analyzed from May to September 2021 in the Lanxi section of Qiantang River. FiSAT II software program was used. The growth coefficient K = 0.21 year -1 , asymptomatic length L ∞ = 39.48 cm, and age at theoretical zero-length t 0 = -0.74 years were estimated. The von Bertalanffy growth function was calculated as L t = 39.48[1 -e -0.21(t + 0.74) ]. The growth curve for weight had an inflection at 5.86 years, corresponding to 29.61 cm in standard length and 372.29 g in weight. The natural mortality rate (M), the fishing mortality rate (F), and the total mortality rate (Z) were calculated as 0.51, 0.61, and 1.12 year -1 , respectively. The exploitation ratio (E) was 0.54, which is greater than the value of 0.5 suggested by Gull (1971), indicating a probable state of overdevelopment. The annual average stock number and biomass of S. curriculus in the Lanxi section of Qiantang River were 31.86 × 10 6 individuals and 3656.82 t, respectively.
