TEMPORAL AND SPATIAL VARIATIONS OF SELECTED WATER QUALITY PARAMETERS IN SERGESTID SHRIMPS’ HABITAT ALONG COASTAL WATER OF MIRI, SARAWAK, MALAYSIAN BORNEO

Evidences have shown that coastal water as habitat support various flora and fauna well nursery ground which highlight the importance of quality monitoring act basis for productivity fisheries. Therefore, objective this study is to analyse temporal spatial variations selected parameters in sergestid shrimp’s along Miri, Sarawak. Nine namely dissolved oxygen (DO), temperature, turbidity, pH, salinity, chlorophyll a (chl a), total suspended solid (TSS), nitrate (NO3-) orthophosphate (PO43-) were measured four stations Miri water. The variation explained by principal component analysis had variance 55.95%. PC1 shows waters July 2017, September October December 2017 January 2018 characterized with high turbidity TSS low temperature salinity. In contrast, November March April warmer clear salinity reading, whereby blooms shrimps observed 2018. PC2 result May June pH reading. Overall, all close standard value Class E Malaysian Marine Water Quality Standards (MMWQS).
