Abstract

This study aimed to evaluate the effects of different temperatures on growth, feed filtration rate, and survival rate of pearl oyster spat (Pinctada maxima). The research was conducted using a Completely Randomized Design with three temperature treatments (control/room temperature 29-31°C, 32°C, and 34°C) and four replications. Twenty-five-day-old spats were reared for 21 days in containers containing 10L of seawater with a density of 75 spats per container. Results showed that temperature significantly affected (p<0.05) spat growth and filtration rate. The highest growth was found at 34°C treatment with absolute growth of 5.11±0.05 mm, relative growth of 211.2±2.25%, and specific growth rate of 5.55±0.04%/day. The highest filtration rate was also recorded at 34°C (140.4±2.1 ml/hour/spat). However, the highest survival rate was found at 32°C (83.3±2.6%). These results indicate that temperatures of 32-34°C can be recommended for pearl oyster spat cultivation, considering the balance between optimal growth and survival rate.
