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.

Abstract

Sugian Village, Sambelia Subdistrict, East Lombok, has great potential for developing pearl oyster (Pinctada maxima) aquaculture-based marine tourism (minawisata). This community service activity aimed to provide counseling to local youth regarding pearl oyster spat rearing as a sustainable alternative livelihood. Through counseling methods involving theoretical and practical sessions, participants gained knowledge about pearl oyster aquaculture techniques, from spat rearing to grow-out. The results of the activity showed a high level of enthusiasm among the youth of Sugian Village to develop pearl oyster aquaculture business and promote it as a new marine tourism attraction. The knowledge gained from this counseling is expected to foster sustainable livelihoods and marine resource conservation in the area.
