AbstractTemporal variation of fish larvae during the winter-summer transition in Cabrera National Park (SE Mallorca) reveal two spawning strategies of coastal species; (1) a few species spawn early in the year coupled with the zooplankton biomass peak (e.g. Diplodus sargus, Boops boops), and (2) a larger proportion of species spawn in early summer when hydrographic conditions are milder but food availability is lower (e.g. Coris julis, Serranus hepatus). Specific abundances in spring were fairly higher than in summer (~7 fold). We interpret these strategies on the basis of food availability and change in coastal circulation.
