The present work analyzes data from Madagascar Holothurie Société Anonyme to determine the effect of water temperature on the survival and growth of Holothuria scabra juveniles in ponds, and tests a system for heating pond water during the cold season (April–August). Our study shows that while water temperature does not affect the survival of endobenthic juveniles of H. scabra it greatly affects their growth. We strongly recommend using a system to shade farming ponds during the hot season (September–March), and a water heating system such as greenhouses during the cold season.
