BACKGROUND & OBJECTIVES Exposure to air pollution due to combustion of biomass fuels remains one of the significant risk factors for chronic respiratory diseases such as chronic bronchitis. There is a need to identify the minimum threshold level of biomass index that is significantly associated with chronic bronchitis. This study was undertaken to identify a threshold for biomass exposure index...

A freshwater "mussel mortality threshold" was explored as a function of porewater ammonium (NH4+) concentration, mussel biomass, and total nitrogen (N) utilizing a numerical model calibrated with data from mesocosms with and without mussels. A mortality threshold of 2 mg-N L-1 porewater NH4+ was selected based on a study that estimated 100% mortality of juvenile Lampsilis mussels exposed to 1.9...

Data from 4,713 fisheries worldwide, representing 78% of global reported fish catch, are analyzed to estimate the status, trends, and benefits of alternative approaches to recovering depleted fisheries. For each fishery, we estimate current biological status and forecast the impacts of contrasting management regimes on catch, profit, and biomass of fish in the sea. We estimate unique recovery t...

Six most abundant and commercially valuable croakers (Sciaenidae) stocks in the coastal water of Bangladesh were evaluated using a length-based Bayesian Biomass (LBB) approach. The ratios B/B0 (current relative biomass) smaller than BMSY/B0 five six stocks. For estimated populations, two (Otolithes ruber Pterotolithus maculatus) are grossly overfished, one (Otolithoides pama) is (Johnius belang...

Time series of catch and effort data for Farfantepenaeus notialis were analysed in ‘R’ using a limited state-space Bayesian Catch-maximum Sustainbale Yield (CMSY) method stock assessment from (tonnes) abundance (t/day). The study categorically compared the status F.notialis two periods (1981-1996) (2008-2018) denoted as I II, respectively. Results management based on Schaefer model (BSM) analys...

Assessment of fish stock status is generally required for fisheries management, which difficult when the data are limited. The length-based Bayesian Biomass (LBB) approach a powerful and new method, where only length-frequency used estimating resources. Here, we applied LBB method to assess seven commercially valuable marine fishes from northern tip Bay Bengal (BoB), Bangladesh. These species w...

State of the greenland halibut stock in Sea Okhotsk fishing zone is evaluated as overfished with a high probability 97.5 % by index fishable biomass, and overfishing continued 2021. This conclusion based on results double filtering posterior parameter estimates state-space generalized surplus production model JABBA (Just Another Bayesian Biomass Assessment), additional tuning new taking into ac...

The islands of Madeira and Selvagens are less than 300 km apart but offer a clear contrast between a densely populated and highly developed island (Madeira), and a largely uninhabited and remote archipelago (Selvagens) within Macaronesia in the eastern Atlantic. The Madeira Archipelago has ~260,000 inhabitants and receives over six million visitor days annually. The Selvagens Islands Reserve is...

This contribution is a response to the rebuttal of Agnew et al. (2012) to Froese and Proelss (2012) “Evaluation and legal assessment of certified seafood”. It corrects some factually wrong statements in the rebuttal, revisits the definitions of ‘depleted’ and ‘overfished’, and notes that the rebuttal agrees with the international definition of ‘overfishing’ (F > FMSY) that was used by Froese an...
