“…No fish older than 3 yr were found amongst sampled fish in this area. In the Bay of Biscay, the dataset on length and weight at age is that used in Gatti et al (2017). The data on adult fish (10 446 fish) are from multipleyear small pelagic surveys in spring (2000 to 2011), the data for larval fish are from dedicated spring and summer surveys (1999, 2008 and 2010), and juvenile data were collected from autumn surveys (1999, 2003 and 2005).…”

“…Furthermore, it was used to understand the mechanisms behind the recent spatio-temporal shift in the distribution of sole and plaice in the North Sea (Teal et al 2012). In the Bay of Biscay, an up dated DEB parameterisation for anchovy, and a new one for sardine, recently allowed for a comparison of biological traits between the 2 species (Gatti et al 2017).…”

“…The batch frequency is dynamic (0.25 d −1 on average) depending on temperature and energy in E R that controls the kinetics of energy allocation to gametes (see Fig. 2 and Gatti et al 2017).…”

“…The comparison was based on simulations with a full life-cycle bioenergetics model, forced by temperature and food resources, the values of which are provided by regional coupled physical−biogeochemical models, and supported by available observations. Our bioenergetics model is based on the Dynamic Energy Budget (DEB) theory (Kooijman 2010), and was previously parameterised for anchovy in the Bay of Biscay by Gatti et al (2017). With our comprehensive modelling framework, we aim to better understand which factors drive the regional differences in the observed growth and reproductive traits.…”

Anchovy Engraulis encrasicolus distribution in European waters spans from the Mediterranean Sea to the North Sea, and is expected to expand further north with global warming. Observations from the eastern Mediterranean (North Aegean Sea), the Bay of Biscay and the North Sea reveal latitudinal differences in growth, maximum size, fecundity and timing of reproduction. We set up a mechanistic framework combining a bioenergetics model with regional physical−biogeochemical models providing temperature and zooplankton biomass to investigate the underlying mechanisms of variation in these traits. The bioenergetics model, based on the Dynamic Energy Budget theory and initially calibrated in the Bay of Biscay, was used to simulate growth and reproduction patterns. Environment partly explained the increased growth rate and larger body size towards the north. However, regional calibration of the maximum assimilation rate was necessary to obtain the best model fit. This suggests a genetic adaptation, with a pattern of cogradient variation with increasing resource towards the north, in addition to a countergradient thermal adaptation. Overall, the seasonal energy dynamics supports the pattern of body-size scaling with latitude, i.e. food-limited growth but low maintenance costs in the warm Aegean Sea, and larger size in the North Sea allowing sufficient storage capacity for overwintering. Further, the model suggests a synchronisation of reproductive timing with environmental seasonality as a trade-off between thresholds of temperature and reserves for spawning and overwintering, respectively. Finally, low temperature, short productive and spawning seasons, and insufficient reserves for overwintering appear to be current limitations for an expansion of anchovy to the Norwegian Sea.

“…The energetic content of zooplankton is also very variable among species, size class, area and season (Barroeta et al, 2017;Dessier et al, 2017). Energetic condition indices such as ED are also of large interest for bioenergetic modelling (Gatti et al, 2017;Hartman and Brandt, 1995;Pecquerie et al, 2009) and for food web modelling (Albo-Puigserver et al, 2017). Furthermore, small pelagic fish condition, e.g.…”

Highlights ► Exploration of energy density sources of variability: species, season, region, size. ► Relationships between dry mass content and ED are strong but species specific. ► Larger length, mass and ED at age in the English Channel than in the Bay of Biscay. ► Sardine display larger energy reserves than anchovy. ► Larger reserves are likely in link with larger spawning or maintenance costs. ► A strong scaling of ED with size with a dome shape pattern for sardine. ► Decrease of ED with size is discussed in link with feeding and spawning behaviours.
