This project aims to develop the artificial breeding techniques for Blenniidae fishes from stock rearing, natural spawning, larvae and juveniles care. The executive of this project is important especially for coral reef fishes because artificial breeding of these fishes is the best way to prevent overfishing from their native environments. are the main marine Salarias fasciatus aquarium fish species. In this study, we will collect high-value blenniidae brood stock and to establish larviculture technologies. Under heat stress experiments, blue devil was caused to die at 37.2 ℃, and all fish die when the temperature reached to 38.5 ℃. In the low temperature tolerance test, fish cause to die at 15.1 ℃ and all fish die at 13.2 ℃.
