“…That is why this study reiterates the need for a posteriori studies to confirm the hypothesis of fishing pressure as a maturity driver in order to have a better understanding of the underlying dynamics of this stock. Additionally, the impact of the reduction in the L 50 in males on the reproductive potential of the stock should be also investigated as paternal effects have proved to be more important than previously thought in stock dynamics (Dominguez-Petit et al 2022).…”

European hake (Merluccius merluccius) is a commercially important resource in Iberian Atlantic waters. Despite the recovery plan implemented in 2006 and the multiannual management plan for western waters, fishing mortality is still higher than that corresponding to the maximum sustainable yield for the southern European hake stock. The biological processes underlying the dynamics of this stock and its life history traits are essential for assessing population productivity and resilience, making them basic information for management. We analysed the temporal variability of size at maturity (L50) of this species and the main factors influencing it in Atlantic Iberian waters from 1982 to 2019. The annual variability of L50 for each sex was modelled with generalized additive models, considering explanatory environmental variables (Atlantic Multidecadal Oscillation, North Atlantic Oscillation and sea surface temperature) and biological variables (biomass, spawning biomass at length and relative condition factor). The results showed that the L50 of males decreased by a total of 12.9 cm and L50 of females decreased by a total of 10.9 cm from 1982 to 2019. For females the significant explanatory variables were year, spawning biomass at length, biomass and the North Atlantic Oscillation, while for males only year was an explanatory variable. These results are important for understanding the status of the European hake population, signalling that L50 is a good indicator for predicting future population dynamics.

The mean weight-at-age of fish species is an indicator of fish growth and physiological condition, as well as a basic parameter for assessing and managing fish stocks. Here, we investigate the temporal trends of the mean weight-at-age of four different commercial species with different life strategies: (i) the short-lived pelagic European sardine (Sardina pilchardus), (ii) the horse mackerel (Trachurus trachurus) and two medium-lived benthic, (iii) the megrim (Lepidorhombus whiffiagonis) and iv) the four-spotted megrim (Lepidorhombus boscii), in North Atlantic Iberian waters from 2000 to 2018. Generalised additive models were implemented to identify the main (density-dependent and density-independent) drivers of fish weight-at-age variability: abundance, sex, maturity, sea surface temperature, sea bottom temperature, North Atlantic Oscillation (NAO) and Atlantic Multidecadal Oscillation indices. In all four species, abundance had a negative effect on mean weight-at-age. Temperature affected mean weight-at-age in sardine and megrim, while NAO influenced it in horse mackerel and four-spotted megrim. In the case of the sardine, we observed a progressive decrease in the mean weight-at-age of adults in the series in contrast to the four-spotted megrim; however, there was no effect of year on either horse mackerel or megrim. We discuss the influence of life strategy on fish response to drivers.
