  ABSTRACT
  Pagellus acarne (Risso, 1827) (Perciformes Sparidae) represents an important component of Algerian fishery catch. Reproduction and growth parameter of this species are studied during 13 months, from fish catched from western Algerian coasts from December 2015 to December 2016. The sex-ratio (F:M) of the population studied is 1:1.56 and is in favor of male. The reproductive season extends between late spring and autumn. The resting period occurs in winter. Length at first maturity is estimated at 18.63 cm and 16.95 cm for females and males respectively. The length-weight relationship obtained is TW=0.009TL^3.086 (R²=0.983). The Von Bertalanffy growth equation parameters are K=0.41, L∞=29.97, t₀ =-0.34 and the Φ’=2.57.
