“…Unfortunately, this representation does not consider the species that are not in the area but could arrive due to changing conditions, and can potentially deteriorate ecosystems (Occhipinti‐Ambrogi, 2007). Empirical evidences demonstrated large movements of indigenous and non‐indigenous species in the area: an abrupt northward shift of small pelagics from the Eastern English Channel to the North Sea occurred in the middle of the 1990 s, partly due to climate conditions (McLean et al, 2018), while for the first time Mediterranean species were recently recorded in the Eastern English Channel (Mahé et al, 2012, 2014), and a tropical species was recorded in the North Sea (Cresson et al, 2017). In general, stocks with smaller body size and faster life history characteristics will better adapt to warming (Free et al, 2019; Moullec et al, 2019; Perry et al, 2005).…”

Climate change is already known to cause irreversible impacts on ecosystems that are difficult to accurately predict due to the multiple scales at which it will interact. Predictions at the community level are mainly focused on the future distribution of marine species biomass using ecological niche modelling, which requires extensive efforts concerning the effects that trophic interactions could have on the realized species dynamics. In this study, a set of species distribution models predictions were used to force the spatially‐explicit trophic model Ecospace in order to evaluate the potentials impacts that two 2,100 climate scenarios, RCP2.6 and RCP8.5, could have on a highly exploited ecosystem, the Bay of Seine (France). Simulations demonstrated that both scenarios would influence the community of the Bay of Seine ecosystem: as expected, more intense changes were predicted with the extreme scenario RCP8.5 than with the RCP2.6 scenario. Under both scenarios, a majority of species underwent a decrease of biomass, although some increased. However, in both cases the stability of the majority of species dynamics was lowered, the sustainability of the fishery. Differences between niche modelling predictions and those obtained through the forcing in Ecospace highlighted the paramount importance of considering trophic interactions in climate change simulations. These results illustrate the requirement of multiplying novel approaches for efficiently forecasting potential impacts of climate change.

“…For instance, S. porcus can be confused with other Scorpaena species in terms of both coloration and morphological characters. S. porcus was known as the black scorpionfish, but in a study conducted in the eastern English Channel, a sample of a red-colored fish was reported to be molecularly S. porcus species (Mahé et al, 2014). Besides, there were overlaps in dorsal fin rays and morphometric features of Scorpaena species (Akalın et al, 2011;Froese and Pauly, 2021), and these overlaps were more common in juvenile samples (Akalın et al, 2011).…”

“…Nevertheless, D. parini was not observed before in the North Sea, suggesting that it is not established but may migrate away from the boundary of its habitat, as a response to change in environmental conditions (Rose, 2005). This hypothesis was previously proposed to explain captures of Mediterranean species in the English Channel (Mahé et al, 2012(Mahé et al, , 2014.…”

In June 2015, an individual of Diretmichthys parini (Post and Quero, 1981) was trawled at 530m depth, in the North Sea off Norway and donated to research. This capture, the first for this species in the North Sea was the northernmost recorded so far, and provided an opportunity to document some aspects of the biology and ecology of this data-poor species. This individual was a female, 331mm total length of 33years old, with low mercury content in muscle and liver (~0.2μgg wet mass). Stable isotope ratios (C and N) in muscle and liver were consistent with the planktonic diet expected for this species. The capture of this fish at the northern latitude known so far would be consistent with the extension of the home range and the latitudinal shift hypothesized for this species in the 1990's.
