Sažetak
One Coryphaena hippurus juvenile was found swimming in a bucket at the open sea in the Adriatic on July 29. 2008, about 12 miles south of Bisevo Island. These fishes are often attracted to various floating objects and this individual was probably swimming under the object, but was somehow trapped inside. The other specimen was found free swimming close to the sea surface on July 05. 2003 near the south-east side of the Bisevo Island (Veli Žardin cove) and was caught by the hand net. Prior to these findings, two larvae were found near Vis island. These findings suggests that actual spawning ground of this species could be located somewhere around the remote Adriatic islands Vis and Bisevo and that spawning in the Adriatic takes place in period from June to August which is corroborated by the fact that period of spawning in western Mediterranean is from June to July. In the last few years, records of larval and juvenile stages of the species that were previously rare or relatively rare in the Adriatic became more common. Findings of early life stages of C. hippurus could be a consequence of new climatological and oceanographical conditions in the Adriatic as well as in the Mediterranean Sea. These conditions are probably also a key reason for the increased abundance of C. hippurus in the Adriatic in the recent years. Prior to these, no records of such early life stages existed for the Adriatic, therefore, it is reasonable to conclude that reproduction of dolphinfish in the Adriatic is a recent adaptation to a new and changing enviroment.
