The Growth Performance of Abalone Shells (Haliotis squamata) with Different Types of Macroalgae Feeding in Polycultural Cultivation with Snubnose Pompano (Trachinotus blochii)

Polyculture system is one of the cultivation efforts by using two different types of biota in the same environment at the same time. Abalone (Haliotis squamata) and Snubnose pompano (Trachinotus blochii) are two species that show complementary potential in polyculture systems. In polyculture systems, Abalone feed is generally macroalgae. Different types of macroalgae can have different impacts on the growth and survival of Abalone and snubnose pompano in polyculture systems. Therefore, this study aimed to analyze the growth performance of Abalone mussels by feeding different macroalgae. This study used an experimental method with a complete randomized design (CRD). The results showed that different types of macroalgae feed in the maintenance of Abalone mussels with snubnose pompano had a significant effect on growth (absolute length and absolute weight) and the best survival of Abalone (Haliotis squamata) was in maintenance with Gracilaria sp
