An ecological niche modelling (ENM) approach was developed to model the suitable habitat for 0-group European hake, Merluccius merluccius L., 1758, in Mediterranean Sea. The ENM built combining knowledge on biological traits of hake recruits (e.g. growth, settlement, mobility and feeding strategy) with patterns selected variables (chlorophyll-a fronts concentration, bottom depth, sea current temperature) highlight favourable nursery habitats. results show that nurseries require stable...
Summary 1. The development of ecosystem approaches to environmental management implies the need account for multiple pressures on ecosystems. Trends in metrics that respond differently changes major be combined evaluate impacts fishing and fish communities. 2. An exploited community is viewed as a three‐level food chain which two upper levels, or functional groups, are targeted by fleets, while lowest level subject variation. Qualitative modelling used predict at is, top‐down vs. bottom‐up...
The present work attempts to study the spatio-temporal distribution of Mullus barbatus and M. surmuletus in Mediterranean Sea by using a time series data from an international bottom trawl survey that covered wide area Sea. experimental surveys were accomplished annually 1994 2000 on approximately 1000 pre-defined sampling stations distributed 15 major areas. Selection was based depth-stratified random scheme included five depth strata: 10-50, 50-100, 100-200, 200-500 500-800 m. examined...
Large-scale studies focused on the diversity of continental slope ecosystems are still rare, usually restricted to a limited number indices and mainly based empirical comparison heterogeneous local data sets. In contrast, we investigate large-scale fish basis multiple using 1454 standardized trawl hauls collected throughout upper middle whole northern Mediterranean Sea (36°3'- 45°7' N; 5°3'W - 28°E). We have analyzed (1) relationships between set 11 in order assess their degree...
Recent theoretical and field studies conducted in both terrestrial marine ecosystems have suggested that diversity could be a more complex multi‐component concept than previously thought. However, it is still poorly understood to what extent the information provided by various indices complementary with regard diversity, this complementarity reproducible different situations or at scales of observation. In present work, we analysed reproducibility empirical relationships between 11 related...
Abstract. Early-life stages play a key role in the dynamics of bipartite life cycle marine fish populations. Difficult to monitor, observations these are often scattered space and time. While Mediterranean coastlines have been surveyed, no effort has made assemble historical observations. Here we build an exhaustive compilation dispersal traits for coastal species, considering situ growth models (Di Stefano et al., 2023; https://doi.org/10.17882/91148). Our database contains over 110 000...
Fish samples were collected between 1999 and 2002 in the Cabras lagoon, largest brackish area Sardinia one of most important areas for artisanal lagoon fishery Mediterranean area. Because its natural connection with both Oristano Gulf 'Mare e Foghe' river, which pollution problems are frequent, this suffers from dystrophic crises linked to phytoplanktonic or macrophytes blooms. The effect dystrophy on fish population was studied by analysing commercial landings variations modification...
Abstract. Early-life stages play a key role in the dynamics of bipartite life cycle marine fish populations. Difficult to monitor, observations these are often scattered space and time. While Mediterranean coastlines have been highly surveyed, no effort was made assemble historical observations. Here we build an exhaustive compilation dispersal traits for coastal species, considering in-situ growth models. Our database contains over 110 000 entries collected from 1993 2021 various...
[The penaeoid shrimp, Penaeopsis serrata, previously known from the western Atlantic South Carolina to Caribbean Sea, and Morocco in eastern Atlantic, is reported for first time middle-west Mediterranean Sea. The record based on eleven adult females, collected by trawling a muddy bottom Sardinian Channel between 490 540 m depth. Considering that sampling area has been studied long period, it can be stated P.serrata entered only recently. La specie diffusa sia Atlantico orientale che...
