The FishMed database provides traits, phylogeny, current and projected species distribution of Mediterranean fishes, and associated sea surface temperature (SST) from the regional oceanic model NEMOMED8. Data for the current geographical distributions of 635 Mediterranean fish species were compiled from a published expert knowledge atlas of fishes of the northern Atlantic and the Mediterranean (FNAM) edited between 1984 and 1986 and from an updated exotic fish species list. Two future sets of projected species distributions were obtained for the middle and end of the 21st century by using an ensemble forecasting approach for 288 coastal Mediterranean fish species based on SST according to the IPPC/SRES A2 scenario implemented with the Mediterranean...

We investigated the trophic niches and the resource partitioning of two snook species, the common (Centropomus undecimalis) and the fat snook (C. parallelus), in four tropical estuaries of the northeastern Brazil, using stable isotope analyses of carbon (δ13C) and nitrogen (δ15N). Fish specimens, mainly juveniles, basal resources and a primary consumer were collected in 2015 during dry and rainy seasons in all estuaries, which exhibited differences in system size, geomorphologic shapes, levels of sea access and anthropic pressures. Potential effect of factors like fish body length, estuary and seasonality on isotope ratios were investigated. Positive relationships between the size of fish and δ15N values were found, regardless the species. Our results...

Ce document s’adresse à un public large, familier ou non avec les problématiques couvertes par la Directive Cadre “Stratégie pour le Milieu Marin” (DCSMM). Ce public inclut donc le personnel intervenant sur la mise en oeuvre de la DCSMM, les scientifiques, et toute personne concernée par la surveillance de l’état de santé du milieu marin. L’objectif du document est de valoriser les travaux menés lors des essais du Programme de Surveillance de la DCSMM. Ces essais ont consisté à tester des protocoles visant à utiliser les campagnes océanographiques bentho-démersales et pélagiques existantes pour collecter les données indispensables à la construction et au renseignement d’indicateurs du Bon État Écologique. Cette collecte de données implique la participation...

An end-to-end model to evaluate the sensitivity of ecosystem indicators to track fishing impacts
Provedor de dados: 5
Autores: Halouani, Ghassen; Le Loc'H, François; Shin, Yunne-jai; Velez, Laure; Hattab, Tarek; Romdhane, Mohamed Salah; Ben Rais Lasram, Frida.
In order to assist fisheries managers, ecological indicators are needed to evaluate the effects of fishing activities on marine ecosystems and to improve communication of these effects in both public and scientific contexts. Finding appropriate indicators is challenging given the complexity of marine food webs as well as the ecosystem response to fishing pressure. In this study, an end-to-end model developed in the Gulf of Gabes ecosystem (Tunisia) was used to compare the performance of a set of ecosystem indicators in assessing the impact of fishing. This end-to-end model aimed to represent the ecosystem functioning by coupling two existing sub-models, the multispecies individual-based model OSMOSE, representing the dynamics of exploited species and the...
