The Vannamei Prawns Aquaculture based Coastal Carrying Capacity in The Coast Areas of Indramayu

Abstract

The utilization of coastal area nowadays is commonly used for vannamei prawns aquaculture, either with traditional technology “plus” and intensive technology. The regency of Indramayu is a district in which coastal regions are now utilized to vannamei prawns aquaculture. The uncontrolled development of this aquaculture farming will cause an impact on the surrounding environment, and will eventually threaten other environment sectors in the coastal areas of Indramayu. This research was aimed to calculate the carrying capacity of the coastal area in sub-district of Indramayu. The analysis of the carrying capacity used the approach of Rakocy and Allison (1981) which stated that waste water recipient amounts to 100 times the volume of waste, in addition to using the assumptions developed by Boyd and Musig (1992) stated that the maximum feed in prawn ponds, the volume of waters using a model developed by Widigdo and Pariwono (2003). Water quality parameters used Total Suspended Solid (TSS). The measurement results of the carrying capacity amounted to 83.50 Ha. Based on spatial analysis, the area of prawn ponds in sub-district of Indramayu was 890 Ha, when compared to the carrying capacity analysis based on TSS, the shrimp pond area in Indramayu District has over-exceeded the carrying capacity. In conclusion, the carrying capacity of the coastal area for vannamei prawn aquaculture was 83.50 Ha. Keywords:
