Summary: This study examines the relationship between the economic value estimated by the fisher community and environmental factors in oyster farming marine areas in Japan. The results show that the economic value is correlated with oyster feeding efficiency, indicating that the local fisher community uses empirical evaluation based on local knowledge to determine the value of different locations for feeding. This suggests that economic evaluation based on local knowledge is biologically reasonable and reliable.

Summary: This study used RAD-seq to analyze the genetic differentiation and structure of vendace in the Bothnian Bay. The results showed clear genetic differentiation between River Kalix and other sampling locations, as well as weak structuring between samples from the Swedish and Finnish coast. Outlier analysis identified SNPs associated with salt-tolerance and salinity stress. This study provides valuable insights for fisheries management and demonstrates the power of RAD-sequencing in detecting genetic structuring.

Summary: The global demand for fish keeps increasing, but the production from capture fisheries is decreasing. In the Eastern African Region, open-access nature has led to illegal fishing activities. Although small-scale fisheries play a crucial role in food security and livelihoods, inland fisheries in the region face vulnerabilities and inadequate management solutions. This review examines the production potential, challenges, opportunities, and management of inland fisheries in the EAR. It is expected that aquaculture will become more important in meeting the growing demand due to shortfalls in capture fisheries.

Summary: The collapse of oyster populations and the fisheries they support has been a worldwide phenomenon, but studies of oyster demography in situ prior to and after the collapse have been rare. We used time series of stage-based counts of eastern oysters Crassostrea virginica in Apalachicola Bay, Florida, to help understand how abundance and demographic rates may have changed in the decade after the 2012 collapse relative to the period before the collapse. Based on our demographic analyses, mortality rates of Apalachicola Bay oysters in the decade after the collapse generally exceeded (often greatly so) those during the precollapse period for all oyster stages. On the other hand, spat settlement rates apparently were increasing prior to the collapse and remained high during the postcollapse period.

Summary: Rhinopristioid rays are among the most globally threatened cartilaginous fishes, with limited understanding of their fishing and trading activities in Bangladesh. Due to overfishing and international trade, their populations are declining rapidly, calling for urgent measures to protect this species.

Summary: Connectivity of fish populations in Shark Bay, Western Australia, is influenced by salinity differences at a local scale, while compositions within different inner gulfs are similar. This suggests that Lethrinus laticaudis may have small-scale connectivity throughout their life cycle.

Summary: This study assessed the stock status of three sardines in the Bay of Bengal using the LBB method. Results showed overfished biomass for S. fimbriata, and healthy biomass for D. acuta and D. elopsoides. Additionally, overfishing status was observed for S. fimbriata but safe fishing status for D. acuta and D. elopsoides.

Summary: Indigenous fishing communities in Alaska have been disproportionately impacted by policies privatizing access to commercial fisheries, leading to negative effects on their cultural lifeways, family systems, household economies, and community health. A community-based study in Bristol Bay, Alaska, explores the connections between the dispossession of commercial fishing rights, cultural and community changes brought on by fisheries privatization, and colonial violence. The findings highlight the socio-cultural effects of privatization processes, which contribute to violence against women and substance abuse in rural areas of Alaska. These findings support the importance of Indigenous Ocean justice in advancing Tribal sovereignty and self-determination in fisheries management.

Summary: Ecosystem-based management is considered promising for addressing anthropogenic pressures in marine ecosystems. A data-limited assessment approach has been proposed for identifying ecological production units in the exclusive economic zone of Vietnam.

Summary: Ecosystem-based fisheries management (EBFM) and fisheries co-management have not received sufficient attention for their potential complementarity, with literature review showing that these two management concepts can be integrated in practice, with elements of co-management often seen in traditional management regimes and elements of EBFM appearing in fisheries co-management initiatives.

Summary: This study compared the growth of tropical oysters using standard von Bertalanffy growth function (VBGF) and seasonally-oscillating VBGF (soVBGF), finding that the soVBGF method better fit the growth of oysters and provided different estimates for stock parameters compared to the standard VBGF method. It was concluded that using the standard VBGF on tropical fish stocks exhibiting seasonality may lead to misleading management decisions, due to potentially overestimating biological reference points.

Summary: Small-scale fisheries play a crucial role in global seafood production, but it is important to understand the factors that regulate their carbon footprint. A study in Northwest Mexico found that the fuel intensity per kilogram of seafood increases significantly as fishery biomass decreases. This highlights the need to end overfishing, rebuild fish stocks, and minimize intensive fishing practices to reduce carbon emissions from motorized wild-catch fishing.

Summary: The disconnect between modeling and management needs poses a significant challenge in using information and ideas generated through ecosystem models and analyses for ecosystem-based fisheries management. A case study from the U.S. West Coast showcases a process to identify management priorities, evaluate potential ecosystem models and analyses, and address policy needs, highlighting the importance of structured, iterative, and interactive communication between managers, stakeholders, and modelers.

Summary: The private sector is increasingly recognized as having the capacity to hinder efforts to achieve sustainable ocean-based development, but also to potentially lead towards sustainability and equity with the high level of concentration in the ocean economy.
