Jellyfish blooming are seasonally occurring on the area of PT. Indonesia Power UP Grati on East Java Indonesia. The jellyfish is threats to the power plant operation, by obstructs the cooling system. The study aimed to identify the jellyfish in the area, and fish that live in proximity to the jellyfish schools. The objectives were to identify the jellyfish species and to measure environmental parameters of the area as well. The other observed biotic components are the fish species found and their diet. Results indicated there were five jellyfish species of three genera Acromitus, Catostylus, and Versuriga, found. The jellyfishes are mainly composed by water, with solid components include fat, ash, protein, and carbohydrates, providing potential future nutrition sources. Alongside the jellyfishes, there are 2 fish species, Leiognathus berbis and Ambassis kopsii, and found with tiny shrimp (Acetes indicus). None of these fishes are jellyfish eaters as mostly inside them are microplankton and tiny crustaceans. Through the analysis, it is hypothesized that the fishes regulate the shrimp population, providing more food for the jellyfish and shelter for the fishes as the jellyfish are abundant. Future studies are required to test the hypothetical interactions.
