The results of anchovy stock assessment during surveys in periods 1976-1984 and 1989-1990 are given. The influence of the curves of spawning intensity on the error in stock assessment is also discussed. During the periods of surveys it was observed that anchovy stock was decreasing. Estimates using the batch fecundity method show that anchovy stocks were highly overestimated because their fecundity was underestimated. It is obvious that in future surveys in the Adriatic, the batch fecundity methods has to be applied.
