Specimens of Engraulis encrasicolus (Osteichthyes: Clupeiformes) (Linnaeus 1758) were collected monthly from the Adriatic purse seine fishery from June to December 2013 in order to study the reproductive traits and the condition of the population. Temporal trend of gonadosomatic index and macroscopic examination of the maturity stages of gonads show that the temporal changes in anchovy condition appear to be related to the sexual cycle.

Abstract
Specimens of Engraulis encrasicolus (Osteichthyes: Clupeiformes) (Linnaeus 1758) were collected monthly from the Adriatic purse seine fishery from June to December 2013 in order to study the reproductive traits and the condition of the population. Temporal trend of gonadosomatic index and macroscopic examination of the maturity stages of gonads show that the temporal changes in anchovy condition appear to be related to the sexual cycle. Furthermore, anchovy seems not separate feeding and reproduction over the time.File in questo prodotto:
