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.

Elasmobranch Mark–Recapture Experiment off the Balearic Islands: Insight into Scyliorhinus canicula Growth, Mobility, and Population Size

Fishes, Journal Year: 2024, Volume and Issue: 9(8), P. 315 - 315

Published: Aug. 9, 2024

Despite the high diversity of elasmobranch fishes in Balearic Islands, knowledge their biology and population dynamics is still scarce. A recent mark-and-recapture experiment off Islands tagged 3738 individuals 23 shark batoid species during MEDITS CANAL bottom trawl scientific surveys from June 2021 to August 2023. Retrieval was reported for sharks Scyliorhinus canicula Mustelus mustelus, revealing relatively small home ranges these (0.2–38.5 km 7.8–15.3 S. M. respectively). Recapture efficiency higher than commercial catches, highlighting potential challenges collaboration with fishermen recapture reports. Density estimates obtained survey suggest a much larger mark–recapture data, indicating density this may be overestimated due its scavenger behavior perhaps favoring searching discards aggregated fishing grounds. This study emphasizes importance monitoring, collaborative efforts, improved reporting mechanisms enhance our understanding populations provide support sustainable management vulnerable marine species.
