Sažetak
The present paper describes the recruitment and food composition of thin-lipped grey mullet juveniles in the estuary of the Neretva river. thin-lipped mullet appeared in the Port of Ploče in February. The relationships between total length, standard length, and weight showed a rmarkably good fit to the expected allometric model, with b=3 for total length. Twelve different animal food categories were identified. The addition, six diatom taxa were noted. Harpaticoid copepods were the most common prey (39%) in these samples, followed by insects (32%) and cladocerans (12%). All other prey accounted for less then 4%. Insects represented 99% of prey in the stomachs of specimens sampled from the freshwater Crna rijeka river. Thin-lipped mullet juveniles were not found on sandy beaches or natural bays around the port. It thus appears that juveniles find in the port area to be a habitat with favorable characteristics of a brackish water nursery.
