dc.description.abstractInfluence of food concentration (0.5, 1 and 2 x 10 sup(5) cell ml sup(-1) of Skeletonema costatum), temperature (20 and 30 degrees C) and salinity (15, 25 and 35 ppt) on the larval development of Balanus amphitrite (Cirripedia: Thoracica) was examined. The mortality rate at 20 degrees C was lower than at 30 degrees C in general. INcrease in food concentration from 0.5 to 1 x 10 sup(5) cells ml sup(-1) . The results indicate that food availability and temperature jointly determine the energy allocation for metamorphic progress. It was observed that the influence of the tested variables varied with instar. At 20 degrees C the mean duration of the second instar exceeded 3 d and was much longer than other instar durations. The fourth, fifth and sixth instars and the total naupliar period showed that the effect of different salinities at given food concentrations was negligible at 20 degrees C, while at 30 degrees C there was a marked decrease in duration with increasing salinity
