This study reveals an analytical stock assessment of tiger shrimp in Bangladesh marine waters after three decades of the inclusive survey. A time series of annual Catch Per Unit Effort (CPUE) was derived from commercial logbook data during the period from 1986 to 2017 and used as a tuning series for a Schaefer biomass model through MS-Excel and CMSY\/BSM interfaces. The standing stock and harvest rate were estimated to be around 1250 t and 23% respectively. The estimated Maximum Sustainable Yield (MSY) reference points with 95% confidence interval are optimum biomass BMSY2360 t (1670-3320 t) and optimum fishing mortality Fmsy = 22% (16-31%). The average annual catch of last two decades 308 t, below estimated MSY of 527 t (388-717 t). Overall the stock is estimated to be at alarming state despite average annual catch lower than MSY for the last two decades. The enigma for this loophole likely to be lies indiscriminate exploitation of postlarvae (PL) from nature for coastal aquaculture and an extensive collection of brood shrimp for shrimp hatchery broodstock.<\/p>\r\n\r\n<p><strong>Keywords:<\/strong> MSY, Tiger Shrimp, Bangladesh, SPM, Trawl Catch Log.<\/p>","file":"\/files\/econtents\/5f805b6c85c7fBMJ_V4_Issue_1_artilce_10_suman.pdf","downloaded":10,"created_at":"9\/10\/2020 11:27 PM","updated_at":"7\/12\/2020 5:50 PM"}
