| Summary: | No abstracts are to be cited without prior reference to the author.Environmental factors have recently been modelled to explain recruitment variability of fish stocks in different sea areas. Among those factors, temperature is often the principal variable investigated since temperature regulates the rate in many ecological and physiological processes. Temperature is assumed to influence recruitment directly, through egg and larval survival, or indirectly via its effects on productivity at lower trophic levels. Although several studies have investigated the effect of temperature on recruitment success of several gadoid species in the North Atlantic, a similar analysis is lacking for pelagic species in the same area. In this study, we explore spawning stock biomass and recruitment data for herring (Clupea harengus), and sprat (Sprattus sprattus) stocks in the North Atlantic in relation to temperature and NAO (North Atlantic Oscillation) variation and their geographic distribution. We used a synthetic approach ... |
