Gap Analysis on the Biology of Marine Fishes Across European Seas

Reviews in Fisheries Science & Aquaculture, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 22

Published: Jan. 7, 2025

This review evaluates the current knowledge of essential biological traits (diet, fecundity, maturity, length-weight relationships, spawning, growth, lifespan, and natural mortality) marine fishes across European adjacent waters. These are crucial for ecosystem modeling stock assessments. Using data from FishBase, largest most comprehensive database on fishes, a gap analysis was performed to identify areas research focus corresponding gaps that require further study. Biological coverage is strong in Baltic North Seas but moderate Adriatic, Aegean, Biscay, Celtic, Levantine, western Mediterranean Seas. Well-documented species include conger (Conger conger), thornback ray (Raja clavata), transparent goby (Aphia minuta) which reported all areas. The narrowest concern followed by spawning while mortality fecundity least studied characteristics. Regional variations exist, particularly protected species. Future should filling addressing overlooked (bycatch discarded species) such as with special attention vulnerable groups like sharks rays. Expanding will reduce uncertainties assessments improve models, two widely used tools sustainable fisheries management conservation.

Fisheries-dependent data and information gathered through fisheries-related scientific surveys can significantly contribute to research on the patterns processes underlying marine biological invasions their interactions with fisheries. This study presents an overview of presence non-native fish species in North Aegean Sea, offering insights into distributions impact The findings are based a comprehensive compilation commercial fisheries-dependent survey collected Greece from 2016 2023, along systematic review international literature. resulted documentation 37 species, including several recorded for first time area. results suggest that Sea dynamic.

Scientific knowledge gaps on the biology of non-fish marine species across European Seas

Frontiers in Marine Science, Journal Year: 2023, Volume and Issue: 10

Published: Oct. 3, 2023

Available information and potential data gaps for non-fish marine organisms (cnidarians, crustaceans, echinoderms, molluscs, sponges, mammals, reptiles, seabirds) covered by the global database SeaLifeBase were reviewed eight ecosystems (Adriatic Sea, Aegean Baltic Bay of Biscay/Celtic Sea/Iberian Coast , Black North western Mediterranean Levantine Sea) across European Seas. The review dataset, which is based on published literature, analyzed coverage biological characteristics (diet, fecundity, maturity, length-weight relationships, spawning, growth, lifespan, natural mortality). These are required development ecosystem ecological models to evaluate status resources related fisheries. Our analyses revealed that regarding these in literature was far from complete all studied areas. level available nonetheless reasonably good sea turtles moderate mammals some areas (Baltic Sea Sea). Further, seven have well-studied species terms commercial whereas threatened generally not well studied. Across areas, most cephalopod common cuttlefish ( Sepia officinalis) crustacean Norway lobster Nephrops norvegicus ). Overall, gap narrowest relationships followed growth widest fecundity mortality. Based insights, we provide recommendations prioritize with insufficient or missing address deficiencies.

Profiling the Cypriot Fisheries Sector through the Lens of Fishers: A Participatory Approach between Fishers and Scientists

Fishes, Journal Year: 2024, Volume and Issue: 9(8), P. 308 - 308

Published: Aug. 5, 2024

Despite the sector’s minor contribution (0.5%) to Gross National Product, fisheries sector in Cyprus is particularly important micro economy of coastal communities, offering direct and indirect employment supporting small family businesses. Like any industry, Cypriot faces its own challenges opportunities. The current study aimed identify strengths, weaknesses, opportunities, threats (SWOT) based on fishers’ knowledge provide strategic recommendations identified needs. Following a participatory approach, workshop with 30 small-scale fishers, six large pelagic longline three scientists was conducted November 2023. Fishers worked together conduct SWOT TOWS matrix (a reverse SWOT) analyses. Findings from SWOT–TOWS analyses were used develop for sector. Finally, using Impact–Effort prioritisation method, prioritised according their potential impact effort required implementation. Based analyses, proposes 12 that could significantly improve overall performance sustainability, which if applied will give light hope future
