Abstract
Small pelagic fish are among the main target species of commercial fisheries in the Algerian region. In this study, the reproduction of four small pelagic species in the Algerian basin was investigated. To this, 2053 individuals were sampled, including 996 individuals of Sardina pilchardus, 487 individuals of Sardinella aurita, 494 individuals of Boops boops and 505 individuals of Trachurus trachurus from the Algerian basin between July 2014 and May 2016. Sex ratio results reveal male dominance, except for S. aurita and T. trachurus. Size at first sexual maturity revealed values of 9.41, 13.79, 12.77 and 11.42 cm for S. pilchardus, S. aurita, B. boops and T. trachurus, respectively. The highest absolute fecundity was observed in T. trachurus, followed by B. boops, S. aurita and S. pilchardus.
