Summary: This study developed an Ecopath ecosystem model for the North Aegean Sea and conducted simulations for past and future scenarios. The results indicate that sea temperature changes have varying effects on commercial species, and reducing fishing effort can increase biomass but decrease catches.

Summary: Stocks with low market value are often left out of stock assessments, contributing to the large number of un-assessed fisheries worldwide. A new method, AMSY, was developed to assess stocks with limited data, with the Mediterranean Sea being a focus. In the Aegean Sea, the AMSY method was used to evaluate the status of 74 fish and invertebrate stocks, revealing that targeted stocks have poorer biomass status compared to non-targeted stocks.

Summary: Deep-sea Chondrichthyes, including the kitefin shark Dalatias licha, are highly vulnerable to human impacts due to their late maturation, extreme longevity, low fecundity, and slow growth rates. However, assessing the impact of deep-sea fisheries on these species is challenging due to the lack of fishery data sets and species-specific life history information. This study presents data on the kitefin shark collected as bycatch from deep-water fisheries in the Ligurian Sea, highlighting the rarity, complex ecology, and threats this species faces, emphasizing the need for monitoring and conservation efforts.

Summary: This study investigates the drought characteristics in Buyuk Menderes, Kucuk Menderes, and Gediz basins located in the Aegean region of Turkey, using long-term precipitation and temperature records. The results show that the droughts in the 1980s and 2010s were more severe than in other historical periods. The SPI and SPEI indices did not yield the same results when moving averages were applied, while the DPI and PNI indices showed the highest resemblance.

Summary: Sea cucumbers in the Mediterranean coast of Turkey have a significant commercial importance, but are facing issues of over-exploitation and illegal fishing. Despite the implementation of fishery regulations, illegal activities have remained a challenge. New regulations based on quotas and increased fines have shown some effectiveness in reducing the number of infringements.

Summary: Despite the existing governance structures and policy frameworks, Ghana's artisanal small-scale fisheries are collapsing. This is due to factors such as inadequate education, traditional perception, lack of training in fisheries management, and limited engagement in decision-making processes. To promote sustainable fisheries, effective governance reforms are needed, including capacity building, inclusion, leadership selection reforms, and co-management.

Summary: This study evaluates the economic impact of interactions between dolphins and trammel net fisheries in the coastal waters of the Valencian region. The estimated financial loss per vessel and year due to damages caused by dolphins is euro556, which represents less than 1% of the total yearly income of each vessel in the area. It is suggested to implement economic compensation measures to mitigate hostility towards dolphins and apply conservation measures for their protection.

Summary: The study suggests that phytoplankton diversity indicators are efficient for environmental assessments, but further testing on a broader spatial scale is recommended. Expert knowledge can be used to define impact categories and consider specific pressure types in sub-regional assessments in the Mediterranean Sea. Different diversity indices can distinguish between impact levels, especially showing higher sensitivity in the southern and eastern regions.

Summary: Echinoderms, particularly sea urchins and sea cucumbers, are important in marine ecosystems and are widely used as biological indicators due to their sensitivity to stressors. However, there is limited knowledge about the comparative responsiveness of sea cucumbers. This study aimed to investigate the responsiveness of different echinoderm species to environmental pollution and found species-specific sensitivities to pollutants. Sea cucumbers were found to be more sensitive than sea urchins when exposed to contaminated sediments. These findings suggest that using different echinoderm species in bioassays can provide a comprehensive assessment of the effects of contaminants in ecotoxicological studies.

Summary: The assessment of the status of fisheries resources is crucial for global food security and marine biodiversity conservation. Overfishing has led to the decline of Norway lobster stocks in certain areas of the Northeast Atlantic. This study conducted the first assessment of these stocks using an analytical MSY-based model, revealing extremely low biomass in some areas and long-term temporal and spatial changes in the population dynamic of Nephrops. The findings have implications for sustainable exploitation of Norway lobster stocks and provide insights into the limitations and suitability of production models for crustacean stocks.

Summary: This study provided a detailed description of the morphological characteristics of sharpsnout seabream in the Black Sea Region for the first time. The findings showed that males had higher values for all morphometric characters compared to females. The most variable feature in females was the eye diameter, while in males it was the body depth. The study also found that the total length had the strongest association with the standard length.

Summary: This study investigated the population parameters of the Sharpsnout Seabream in the southern Black Sea Region, including age, sex composition, length-weight relationship, growth parameters, reproduction, and more. The results showed that the average length and weight of the fish were 30.0 cm and 463.9 g, respectively, with a male to female ratio of 1:1.32. Various indices such as growth performance, condition factor, and gonadosomatic index were also calculated. This study is significant as the first research on this species in the Black Sea and will serve as a reference for future studies.

Summary: The striped venus clam plays vital roles in both ecology and economy in the Black Sea coasts of Turkey. The study reveals that the SVE stock density did not change significantly during the closed season. Factors such as catch quantity, environmental factors, food competition, and predation have significant impacts on stock densities and should be considered in fisheries management.

Summary: Estuaries and coastal areas are undergoing rapid changes due to climate change and sea level rise. This research presents a salinity transport model for Biscayne Bay and investigates the potential impacts of altered precipitation, increased salinity/temperature, and sea level rise on bay salinity. The findings suggest that current restoration plans may not be sufficient to maintain current salinity conditions, and management measures such as urban greening, artificial groundwater recharge, and water consumption reduction should be considered.

Summary: The study shows that spatiotemporal simulation modeling is an effective tool for investigating management options in ecosystem-based fisheries management. It demonstrates that fisheries restricted areas can help rebuild the biomass of exploited stocks, but their effectiveness depends on the size and location of the areas. The study also suggests that a parallel reduction in total fishing effort is necessary to achieve the highest benefits of protection.
