ABSTRACT
The anchovy Engraulis encrasicolus (Linnaeus, 1758) is one of the main commercial fish species in the Black Sea, whose stock has undergone a significant decline during past decades, the main factor being overexploitation.
Anchovies are gregarious, pelagic, small-sized and have a crucial role in the circulation of matter in the aquatic environment. As an omnivorous species, anchovy is eaten in its turn by other larger fish, such as the horse mackerel, whiting, dogfish etc.
In order to point-out some aspects of the species’ biology, samples were collected from several stations located along the Romanian Black Sea coast, from stationary fishing points (10 m water depth) during May-September in 2013 and 2014, when anchovies come near the coast for spawning and foraging.
The following population parameters were analyzed: species abundance, frequency on length, weight and age classes and sex distribution. Correlations between length, weight classes and age were also analyzed.
During 2013 - 2014, at the Romanian Black Sea coast the greatest share was held by anchovy individuals aged between 1 and 2 years old with 2 years old predominance and length classes between 8-8.5 and 10.5 - 11 cm. As such, a slight trend of population restoration was recorded.
