Abstract
Akvakultura u današnje doba ima veliku ulogu jer mora namiriti rastuće potrebe čovječanstva za ribom. Akvakuturna proizvodnja danas čini gotovo polovicu svjetske opskrbe vodenim organizmima. U procesu uzgoja organizmi se drže u kontroliranim uvjetima kako bi brže dostigli tržišnu težinu. Uzgoj se može vršiti u kopnenim vodama i u moru. Karakteristične vrste koje se uzgajaju na Mediteranu su lubin, Dicentrarchus labrax (Linnaeus 1758) i orada, Sparus aurata. (Linnaeus 1758). Cilj ovog istraživanja bio je istražiti eventualne razlike u brzini rasta, konverziji hrane i preživljavanju kod lubina i orade s obzirom na vrijeme nasada u plutajuće kaveze. Tijekom istraživanja praćene su jedinke lubina i orade, od nasađivanja do konzumne veličine u uvali Veli Bok na otoku Cresu. Jedinke su nasađene u kaveze u travnju te u srpnju i kolovozu. Svakodnevno je praćena temperatura, a jednom mjesečno su obavljana biometrijska mjerenja jedinki iz svakog istraživanog kaveza. Mlađ lubina nasađena u travnju postigla je konzumnu težinu u kraćem vremenskom razdoblju nego ona nasađena u kolovozu. Mlađ orade nasađene u travnju brže je dostigla konzumnu veličinu, kao i mlađ lubina, u odnosu na onu nasađenu u srpnju. Stopa preživljavanja kod obje istraživane vrste bila je viša od očekivane.
Abstract (english)
Aquaculture has a major role today in order to satisfy the growing needs for fish. Fish farming provides almost half of the world's supply of edible aquatic resources. In the process of aquaculture, fish are kept in controlled conditions in order to more rapidly reach their market weight. The characteristic species that are grown in the Mediterranean are sea bass, Dicentrarchus labrax (Linnaeus 1758) and seabream, Sparus aurata (Linnaeus 1758). The aim of this study was to investigate possible differences in growth rate, feed conversion and survival of sea bass and sea bream, in relation the time of stocking of fingerlings in the floating cages. During the study sea bass and sea bream were monitored in the cages situated in the bay of Veli Bok on the island Cres, from stocking the fingerlings in cages to the market size. Individuals were stocked in cages in April, July and August. The temperature was monitored every day, and biometric measurements of each investigated cage were performed once a month. Sea bass fry transferred in cages in April reached the market size in a shorter period of time than those stocked in August. Sea bream fingerlings stocked in April also achieved market size faster compared to fingerlings stocked in July, similar to sea bass fingerlings. The survival rate was higher than expected for both investigated specie.
