Abstract

To determine the effect of salinity on survival and food utilization of the olive ridley L e p i ~ l ~ ~ c holehl~~u.c~uu ,t he hatchlings of the sea turtle were exposed to salinity ranging from 0 to 100% seawater. Mortality of the hatchlings was maximum in the groups exposed to freshwater. The hatchlings have the capacity to tolerate dilution of salinity upto 25% SW. The feeding rates of hatchlings exposed to 0 and 25% SW were higher (1 228.2 and 11 90.3 J/g/day) than those (803.6 - 879.6 J/g/day) of the 50.75 and 100% SW groups. The conversion rate was the highest in the group exposed to 25% SW (238.7 J/g/day) and the lowest (109.3 J/g/day) in the group exposed to O'h SW.
