Abstract
The Mesangat Swamp is the main habitat of the remaining crocodiles in Indonesia as well as a prime location for nearby fishermen. Fish production as an economic source of society as well as potential food for the Siamese crocodile can continue to be sustainable when the food chain ecosystem is not disconnected with the condition of healthy water quality. Water sampling of ± 1200 ml in each location carried out at 6 (six) locations within the Mesangat Swamp water area. The analysis of water quality is done in the Fishery and marine Sciences laboratories. The quality of the water indicates a n ormal pH, the BOD 0,12 – 1,25 ppm belongs to the low tainted category, COD 15,54 – 40,58 ppm in a category not feasible for the life of aquatic biota, CO2 2,80 – 5,19 ppm good category, low TDS between 65 – 131 mg/L, TSS range 7 – 87 mg/L, DO between 2,86 – 3,19 mg/L, highest nitrate level is 0.21 mg/L while lowest nitrate rate is 0,01 mg/l, water temperature range between 26 – 32oC, The value of Zn (zinc) ranges between < 0,003 – 0,02 mg/L. The difference in water quality at each location can be caused by the tree vegetation cover factor, floating vegetation, river current strength or water flow circulation. Floating vegetation that is widespread in swamp waters is very likely to affect water quality, one example is Salvinia molesta that can restore water quality or vice versa depending on quantity closure on water surface
