Field comparison of sardine post-flexion larval growth and biochemical composition from three sites off the W Mediterranean (Ebro river coast, Bays of Almería and Málaga)

Late larval stages of sardine (16-23 mm) were sampled during the 2003 spawning season in their nursery grounds located off the Ebro river mouth, on the Catalan coast, and in two bays of the Alborán Sea coasts, the Bay of Almería and the Bay of Málaga. The daily growth analysis of each sampled popula...
