【 摘 要 】

Indonesia's marine waters have a variety of flora and fauna species that live and associate therein. This study used an observation method with a descriptive analysis. The results showed that the bivalvia distribution pattern in Segoro Tambak Estuary looked diverse with a distribution index value of 2 in March, and the lowest biomass was 0.95 ton/km2 in January. The highest total average density was 6 ind/10m2 in March and the lowest was 3 ind/10m2 in February. Low wind and current speeds in March caused the highest density and biomass. The content of the organic matter was the following: BOD in the range of 33.38 to 53.89 mg/l from the threshold of
