Analisis Daya Dukung Lingkungan Perairan Di Kawasan Suaka Perikanan Ikan Terubuk Provinsi Riau

Tenualosa macrura is migratory fish species that used to migrate to the Siak River downstream for spawning. The population of that fish, however, declining and it may be caused by environmental degradation and fish exploitation. To understand the carrying capacity of Bengkalis strait, river mouth of the Siak River and Padang strait that represent as migratory area of the fish and those area have been stated as “terubuk conservation area” (424,70 km2). This study aims to determine and analyze the carrying capacity of that area and to estimate the potency of the fish based on the Net Primary Productivity (NPP) and it was conducted in February 2018. Samplings were conducted 6 times, once/ week. Parameters measured were temperature, brightness, current speed, salinity, N, P, pH, DO and clorophyl a concentration. Data on sea surface temparature, PAR (Photosyntetic Active Radiation) and chl-a concentration were also obtained from Aqua MODIS provided by NASA Ocean Biology Processing Group. Based on data obtained from the field, the NPP distribution value ranged from 18.27 to 74.98 mgC/m2/day, while the NPP value that was calculated from the Aqua MODIS data was ranged from 2,208 to 3,272 mgC/m2/day. Based on field obtained data, the carrying capacity of the study area in general was 97.92 tons and the potency was 48.86 tons. Based on Aqua MODIS data, the carrying capacity was 7,356.02 tons and the potency was 3,678.01. In that area, the amount of T. macrura was around 40% of total capture and it can be predicted that the carrying capacity of T. macrura 39.09 tons and the potency was 19.54 tons (based on field data) or the carrying capacity was 2,942.41 tons and the potency was 1,471.20 tons (based on aqua MODIS data). Results of field data based calculation indicate that the carrying capacity and the potency of T. macrura in the study area was lead to overfishing.
