Summary: The study evaluates the status of Indonesian deep demersal snapper-grouper stocks using two length-based methods and compares a literature-based approach with a Bayesian biomass estimation method. While parameter values can impact biomass indicators, stock classification was generally consistent between the two methods, with LBB providing more reliable results and narrower confidence limits.

Summary: The study found that the common hairfin anchovy and Indian perch in 2018 showed a healthy stock biomass status with complete length structures under sustainable fishing pressure, while the others had issues such as exceeding safe biological limits or being overfished. Most of the fish stocks examined showed truncated length structures. The findings provide important fishery reference points that can inform managers and guide various management strategies.

Summary: This study assessed the stock status of Atlantic bonito mainly harvested in the Senegalese Exclusive Economic Zone (SEEZ) using two data-limited approaches (LBB and CMSY). The results indicate that the stock of Atlantic bonito is healthy, but longlines and sleeping nets have a negative impact on the stock.

Summary: The study reveals that there is a serious issue of overfishing in the Beibu Gulf, with 79% of assessed fish stocks being overfished. A high proportion of species were found to have collapsed or were severely overfished in the assessment. The length-based Bayesian biomass (LBB) estimator method was shown to be an efficient tool for evaluating fishery resources in the region.

Summary: This study assessed the maximum sustainable yield (MSY) and stock resource status of Japanese sardine using historical catch data and biological data. The results indicate a healthy and recovering resource status. The study also proposed management strategies for the species, suggesting setting specific target ranges for the medium and long term. The findings suggest that Japanese sardine fishery resource can be sustainably used on a longer time scale.

Summary: Several data-poor stock assessment methods were applied to the Mauritanian pink spiny lobster fishery, all indicating the stock being overfished and in need of biomass rebuilding. Despite uncertain estimates, clear management guidance for sustainable exploitation emerged from the study.

Summary: The aim of this study was to assess the level of red mullet stock exploitation in Georgian coastal waters using CMSY, LBB, and LB-SPR modeling methods. Bottom trawls were used for samplings conducted from 2019 to 2021, with a total of 4957 individuals sampled. The findings suggest that the red mullet stock was overexploited according to the LBB method, and biomass has been decreasing based on CMSY analysis.

Summary: Sharks play an important role in marine ecosystems by restricting and controlling the behavior and population of other species. This study assessed the stock status of four common shark bycatch species in the northern South China Sea using the length-based Bayesian biomass estimation method. The results can be used for the management of shark fisheries in the region.

Summary: The marine fisheries resources of Pakistan have been significantly impacted in recent decades, primarily due to overfishing and the mass exclusion of small and older fish. This study suggests increasing mesh size and reducing the number of boats in order to promote sustainable development.

Summary: Based on data from 1975-1977, 1997-1999, and 2018-2019, the stock of miter squid has shown changes in biological parameters, indicating overfishing since the mid-1980s. To recover the stock, reducing fishing pressure and enforcing size regulations are necessary.

Summary: Fishery resources assessment is crucial for scientific management and sustainable development of fisheries. This study used length frequency data from 2016 to 2020 to estimate various indicators of the Trichiurus lepturus stock in the East China Sea. The analysis revealed overfishing and heavy fishing pressure on the stock, highlighting the need for conservation measures.

Summary: The biomass of Portunus trituberculatus in the Yangtze Estuary is relatively low due to overfishing, as indicated by the LBB method used in this study. Control of catches should be implemented to maintain sustainable levels. The LBB method shows promise in providing a theoretical basis for the management and protection of fishery resources.

Summary: Stock assessments are crucial for fisheries management, and there is a growing demand for assessments based on population dynamics models. The trend is shifting towards using flexible, documented software packages to improve efficiency and consistency. A website has been developed to collate available stock assessment packages and facilitate feedback between users and developers for designing the next generation of assessment tools.
