The population dynamics of the juvenile anchovy, Engraulis encrasicolus (L.),under the estuarine conditions (Novigrad Sea - Central Eastern Adriatic)

The population dynamics of the juvenile anchovy Engraulis encrasicolus (N=2,564) was studied using monthly length and weight frequency data (August 1989 - March 1991) from the central part of the Adriatic Sea(Novigrad Sea and Karin Sea). The von Bertalanffy growth parameters were estimated as L =13.2 cm total lenght, K=0.82 per year and t =-0.5. Mortality rates for all fish, estimated from a length converted catch curve were as follows: total mortality was Z=1.664 per year, fishing mortality F=0.230 per year, with natural mortality M=1.430 per year derived from Pauly's empirical formula.Exploitation rate was E=0.139. Fifty per cent maturity was reached at 9.0 cm total length.
