Sažetak
Effects of temperature, photoperiod and delayed feeding on the larval development and swimbladder inflation in sea bass were studied. Temperature increases from 13 to 19 OC in the early post-larval stage adversely affected sea bass survival and dramatically reduced swimbladder inflation. Exposure to darkness during incubation and early post-larval development resulted in better survival at all tested temperatures and had no effect on swimbladder inflation. Sea bass larvae do not take Artemia nauplii offered 24 h after mouth opening, regardless of the temperature of rearing environment. Exposure of fish to darkness during incubation and early post-larval development did not affect feeding efficiency. Sea bass feeding on Artemia nauplii may be deleted for 72 hours producing no harmful consequences in the later development.
