Demersal and pelagic fish
Changes in community biomass were solely analyzed for the demersal part of the fish community. However, higher proportions of pelagic fish catch relative to demersal fish catch are observed in the three ecoregions with the highest temperatures, i.e. Northern Gulf of Mexico, Carolinian and Floridian. These higher proportions support previously documented patterns in global fish catches towards dominance of pelagic fish towards the tropics (van Denderen et al. 2018) and could have contributed to the observed declines of demersal fish biomass with temperature. The trophodynamic model implicitly accommodated regional variation in pelagic and demersal fish (by way of parameter p ). Although the trophodynamic model confirmed the SEM outcome, it is important to note that not all the decline in demersal fish biomass with temperature should be associated with a direct bioenergetic effect of temperature on fish.
