Abstract

The fecundity of the Black Sea bream from the eastern middle Adriatic (Croatian coast) was assessed by the volumetric method using 59 ovaries in pre-spawning stage from fish between 18.5 and 33.5 cm total length. Estimates of total potential annual fecundity varied between 31,670 and 554,070 eggs per female. Relationships between total potential fecundity and total length (TL), total weight (TW) and age (A) were established using the multiplicative regression model. Relative fecundity is constant, reaching a maximum of 850 eggs per g in the 30.5 cm to 31.0 cm length class.

Summary

Introduction

Knowledge of fish fecundity is useful in investigating the population dynamics of a fish species and for fish culture purposes. The black sea bream (Spondyliosoma cantharus) is a species that lives in inshore waters on rocky or sandy bottoms and Posidonia beds to depths of 50 m (young) and 300 m (adults). Verde Islands (Bauchot and Hureau, 1986). It is very rare in the Black Sea but common in the Mediterranean Sea (Tortonese, 1975) and in the eastern middle Adriatic (Jardas, 1996). In the coastal fishery of Croatia black sea bream form a significant component of the gill net fishery and fish trap catch.
