Sažetak
The paper presents the results of studies on small pelagic fish species which are the biological base of pelagic fishery in Rijeka Bay, Kvarner and Kvarnerić. The catch samples were obtained all year round. The maximum catches (C) and abundance index (CPUE) were obtained in the period of sardine and anchovy spawning ; the highest sardine catches were realized in November (C = 625.749 t) and the highest catch per unit effort was realised in October (CPUE = 36.809 t/boat). The lowest sardine catches (C = 12.493 t) as well as the lowest catch per unit effort (CPUE = 1.562 t/boat/month) were obtained in June (resting phase in the reproductive cycle of sardine). The catches and catch per unit effort of anchovy were highest in August (C=401.439 t) and September (CPUE=42.592 t/boat/month) respectively, which is the spawning period for this species. The lowest catches and CPUE were obtained in November, during the resting phase in the reproductive cycle of anchovy (C= 15.261 t ; CPUE=1.387 t/ boat/month). This is very important for protecting these species.
