POTENTIAL AND APPLICATION OF SARGASSUM EXTRACT IN AQUACULTURE

Aquaculture

Sargassum sp. is a tropical and sub-tropical brown algal species that lives in the subtidal and intertidal regions. Sargassum sp. is a brown algae that produces more alginate than other brown algae. Alginate is used as a raw material for the food, beverage, pharmaceutical, cosmetic and laboratory processing industries. Fish cultivation problems that often occur are fish diseases related to weak conditions of the fish caused by several factors. Some of these factors are the feed-given factor and decreased water quality in cultivation media which could cause various impacts on fish growth. Sargassum sp. contains various nutrients. Among them are 7.94% crude oil, 0.72% fat, 35.84% ash, 4.93% crude fiber, and 50.57% carbohydrates. Sargassum sp. extract potential as antioxidants, antimicrobial and raw material for making surfactant, and so on. The application of Sargassum extract in the fisheries sector can be used to inhibit the growth of Vibrio harveyi, which is the most dangerous cause of firefly disease for Tiger prawn, as a feed additive to increase immunity and provide optimal growth in fish.
