The trade-off between condition and growth shapes juveniles’ survival of harvested demersal fish of the Mediterranean sea

Cross-scale environmental impacts across persistent and dynamic aggregations within a complex population: implications for fisheries management

“…Here, we found that winter SST is the primary driver of red mullet dynamics in the Gulf of Lions. This is in accordance with Kerametsidis et al (2023), who documented that higher winter SST favours the recruitment success of red mullet in the Western Mediterranean. Furthermore, Levi et al (2003) showed that SST anomalies significantly influence red mullet in the Central Mediterranean Sea.…”

“…The number of years of the data that was used in each model as well as the total number of fitted models depending on the number of environmental covariates for each GSA are shown in the right column. viewed as a demographic engine for regional persistence and population dynamics in the Western Mediterranean (Kerametsidis et al 2023). In the Gulf of Lions, by contrast, two areas with persistent aggregations of red mullet were identified.…”

“…As an essential component of local habitats, dynamic environmental conditions can result in spatial restructuring of the stocks with further demographic implications (Szuwalski and Hollowed 2016;Kerr et al 2017). The environment influences critical ecological processes such as recruitment (Houde 2016), spawning (Di Stefano et al 2023) or mortality (Kerametsidis et al 2023), as well as several life history parameters of fish, such as growth or reproductive scheduling (Perry et al 2005;Clark et al 2020). In fact, in some cases, no clear stock-recruitment patterns can be evidenced, which leaves the environment as the main driver of recruitment with minimal influence of the spawning stock (Szuwalski et al 2015;Hidalgo et al 2019b).…”
