Sažetak
The larval development of the freshwater goby species, Vrgorac goby, is described under laboratory conditions. Eggs were pear shaped, 1.4 x 1 mm in size. Hatching occurred 9 to 10 days after spawning, and larvae had a mean TL of 4.27 mm, with the tail fin and all three pairs of otoliths developed and clearly visible. Hatched larvae were positively phototaxic. The mouth opened 2-3 days after hatching (DAH), with larvae feeding independently on the third day. The yolk sac was absorbed and notochord flexion began 6-8 DAH. Metamorphosis was complete at 31 DAH, and juveniles had a mean TL of 10.69 mm and moved towards the bottom of the tank to begin demersal life.
