He territorial water of Bangladesh. S. fimbriata, D. acuta, and D. elopsoides are the most abundant [13,18,19]. Sardines comprise 4.28 from the total marine production in Bangladesh, where a large portion comes from the industrial catch (97 ), and only 3 come in the artisanal catch [22]. Before 2012, the sardine landing was recorded and estimated as “other marine catch”, but GNF6702 custom synthesis following recognizing their significance, separate catch statistics from the landed sardine happen to be started due to the fact 2012. The annual landing of sardine was reported at 20,187 metric tons (mt) in 2012. Following that, a robust rising sardine landing trend was reported till 2017 (48,704 mt) [22]. The landing of sardine that was reported virtually double in 2018 (41,486 mt), compared to its initial report in 2012, however the decline in sardine landing was reported in 2019 (28,256 mt) [22]. The minimum quantity of fishing efforts was 183,102 gears/year (g/yr) observed in 2014, whilst the maximum work was 242,450 g/yr in 2012 and 2013 [22]. The typical landing was 34,135 mt, and also the average effort was 200,201 g/yr reported for sardines in SBP-3264 In Vitro Bangladesh [22]. However, the sudden decline within the sardine landing in 2019 has raised inquiries about its sustainability in the BoB, Bangladesh (Figure 1). Moreover, the alterations within the physicochemical parameters of the water strongly influence the biology and abundance of sardines, that in the end impacts the other marine catches [23]. For that reason, stock assessment may be the main objective for ensuring the sustainability on the fishery stocks in Bangladesh’s marine waters. Regardless of the scarcity of information and experience, Bangladesh has carried out stock assessments on a handful of industrial marine fish species, using distinct stock assessment strategies [4,12,24] without the need of a sardine assessment. Additionally, many research and investigations on sardines’ reproductive morphology, biology, and abundance have been carried out [179]. However, there’s nevertheless a dearth of complete stock assessment info for sardines in Bangladesh. Therefore, the LBB approach was utilised within this study on 3 sardine populations (S. fimbriata, D. acuta, and D. elopsoides) exploited in the BoB, Bangladesh, to evaluate life history traits and figure out the biomass depletion level.J.
