Mollusca Community Structure and Distribution in Jatigede Reservoir Sumedang, as Natural Feed Materials

Abstract

Mollusca live in shallow waters and can be found around the Jatigede Reservoir. Mollusca can serve as indicators of water quality and can be utilized as natural feed materials due to their significant nutritional content. The results showed that the mollusca community structure in Jatigede Reservoir, Sumedang, had Shannon-Whienner diversity index (H') values ​​ranging from 0 - 1.08, categorized as low to moderate diversity. Evenness index (E) values ​​ranged from 0 - 0.76, categorized as low to high evenness. Dominance index values ​​ranged from 0.42 - 1, categorized as moderate to high dominance. Each research station was dominated by the species Filopaludina javanica. Based on the water quality index (FBI), Jatigede Reservoir, Sumedang, is categorized as slightly poor to poor with values ​​ranging from 6 - 6.57. Species found during the study include Filopaludina javanica, Pilsbryoconcha exilis, Anodonta woodiana, Thiara scabra, and Indoplanorbis exustus. Species that can be used as alternative feed materials or supplementary feed materials include Filopaludina javanica
