This study evaluates post-harvest losses among fish farmers and investigates the underlying factors contributing to these losses through a survey of 450 fish farmers and 150 traders. Descriptive analyses reveal notable disparities, with Netrokona district experiencing 34 % physical losses, while Kishoreganj and Sunamgang districts contend with market force losses of 50 % and 40 %, respectively. Insights from <em>Bepari</em> (small-scale traders), <em>Paikar</em> (rural and urban retailers), and general retailers highlight distinct concerns, including a reported 41 % market loss among <em>Bepari</em>, 38 % quality loss emphasized by <em>Paikar</em>, and 40 % market and 30 % quality losses faced by retailers. Farmers attribute these losses to factors such as elevated temperatures and destructive fishing practices, while market participants identify challenges like inadequate storage and transportation delays. A multiple regression analysis reveals critical influencing factors, indicating that age, education, training, and improved transportation positively affect post-harvest outcomes, while selling in secondary and tertiary markets also enhances results. Interestingly, greater labor availability correlates with increased post-harvest losses, potentially due to handling inefficiencies or lack of coordination among workers. This study underscores the necessity for policymakers to devise targeted strategies that address the unique challenges of the haor region, thereby reinforcing Bangladesh's position in global fish production and ensuring the economic sustainability of its farmers and traders.</div></div>","PeriodicalId":48427,"journal":{"name":"Marine Policy","volume":"176 ","pages":"Article 106638"},"PeriodicalIF":3.5,"publicationDate":"2025-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143464319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study presents detailed insights into how the 22 coastal EU Member States (MS) have considered these species under the MSFD and provides recommendations to address gaps and further management and conservation efforts for these species. The review of national and EU-level reports showed a varied integration and consideration of Chondrichthyes in national efforts to reach GES and fulfil obligations in relation to the conservation and management of these species under the MSFD. Across the 168 chondrichthyan species occurring in EU marine waters, 61 have been integrated under either or both descriptors and only 39 species were assessed for GES across the EU, with both positive and negative outcomes. However, the reliance of EU MS on existing programmes for monitoring does hinder effective data collection for Chondrichthyes, leaving substantial data gaps regarding the assessment of species status, habitat conditions, ecology, and distribution.

Thus, a majority of the U.S. EEZ is conserved from the most environmentally adverse fishing activities. These focused geographic areas complement other management tools used to ensure sustainable fisheries and ecosystems, such as catch and bycatch limits and limitations on legal gears, which are often deployed at regional scales. Collectively, these measures meet objectives and MSA National Standards and promote the maintenance of biological productivity and biodiversity, while balancing ecosystem function with services that benefit our nation, such as access to nature through recreational opportunities and healthy, sustainable seafood for consumers.

They are the largest target group in global commercial fisheries, accounting for 30 % of the total catch.

This study is based on fishing data for 11 small pelagic fisheries in a long-term time series from 1963 to 2021. By integrating various machine learning methods and generalized additive models, we quantitatively assess the impacts and differences of typical climate change events (ENSO and AMO) as well as economic development on the catches of different small pelagic fisheries. Our findings reveal the complex nonlinear and asymmetrical effects of ENSO, AMO, and economic development on the catches, with varying degrees of influence. Economic factors predominantly drive changes in the exploitation of small pelagic fisheries. ENSO, AMO, and their lagged effects significantly influence regional fisheries through teleconnections, with ENSO exerting a particularly pronounced impact on the southeastern Pacific area. While most species are adversely affected by the positive phases of climate change, extreme negative phases do not always benefit.

Examining prices from the first-hand sale, wholesale, and retail markets using an asymmetric multivariate GARCH model reveals the retail market exhibits the lowest volatility. Therefore, only a small portion of the volatility from the first-hand sale and wholesale markets is transferred to consumers. Additionally, asymmetries are identified in the transmission of price volatility along the fresh sardine value chain. These suggest that information is not instantaneously transmitted along the supply chain, indicating imperfect market efficiency. Additionally, the wholesale market seems to exert market power, leading to less transparent price formation and potential anti-competitive practices. To reduce price volatility, several policy recommendations can be considered. These include promoting profitable sardine aquaculture to stabilise supply despite technological challenges and implementing sustainable fisheries management practices with improved regulation and more transparent individual transferable quota systems, particularly in the Gulf of Cádiz. Greater market transparency through improved traceability and a simplified supply chain may lead to a more competitive market, reducing volatility in first-hand sales. This volatility fuels the competitive race to exhaust quotas rapidly, resulting in lower prices and reduced fishers’ income. Lastly, it is crucial to consider how external factors, such as online sales platforms, climate change, and recruitment variability in small pelagic species, affect fish landings. Identifying the causes and transmission mechanisms of price volatility can support targeted management and transparency interventions to stabilise revenues and ensure fair competition, benefiting both consumers and fishers.</div></div>","PeriodicalId":48427,"journal":{"name":"Marine Policy","volume":"175 ","pages":"Article 106627"},"PeriodicalIF":3.5,"publicationDate":"2025-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143420682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
