The Relationship between Water Quality and Distribution of Aquatic Biota in Sagara Menyan, Subang West Java-Indonesia

Abstract

Coastal known as thl! aquatic ecosystem have a very large resource potential. This area has been widely utilized and made a significant contribution. However, coastal get constant pressure in the form of ecological pollutants resulting fromhum:m activities. These conditions will lead to a decrease water quality that will bring harm to the aquatic biota. This observation purposed to measure the cllaracteristics of the qu:.lity parameters and the distribution of coastal and estuarine biota in Segara Menyan. Water temperature .. at Segara Mer.yan ranged from 30 to 32°C. Water depths ranged 59 to 250 cm. The transparency ranged 50 .to 89.5 cm. Range levels of DO 1.5 to 5.4 mg/L. Range levels of salinity 30 to 36 psu. Range levels of total ll.hosphate 0.03 to 0.2 mglL. Range levels of nitrate 0.0023 to 0.0257 mgll. Rar.ge levels of nitrite 0.0005 to 0.0058 mglL. Range levels of amonia 0.0071 to 0.2429 mg/L. DJ dan Dz• The range of chlorophyll-a 0.0032 to 0.122 mg/L. Based on the STORET Method analysis obtained, Segara Menyan was fertility waters with medium polluted in water quality~ It has low diversity, low stable community, medium similarity and high . dominance of biota aquatic. Caused by pressure in the form of ecological pollutants originating from human activity and the management indiscretion .•
