Quantify the potential role of environmental fluctuations and changes in status of sardine and anchovy stocks

We present main results of a systematic literature review and a temporal and spatialtemporal modelling exercise to investigate the main effects of environmental factors on anchovy and sardine biomass, abundance, occurrence and landings. During the systematic review, more than 1300 studies were evaluated and assessed to extract available information. Despite the numerous studies, only 40 studies provided quantitative information about relationships between anchovy and/or sardine and the environment. Available data was more abundant for anchovy than for sardine, and adults were more studied that eggs, larvae and juveniles (the least studied). Data was also heterogenically distributed in the Mediterranean Sea. [...]
