Numerical study of hydrodynamic and sedimentation for sustainable marine floating cage aquaculture in Indonesia: a case study in Situbondo, East Java.

Abstract

Abstract In this study, the floating cage aquaculture in Indonesia, specifically the effect on sedimentation in surrounding areas will be studied. In addition to waves and currents, sedimentation is a considerable environmental concern. This result could help establish additional criteria for 1) selecting suitable aquaculture locations, 2) assessing the effect of aquaculture on the environment, and 3) developing sustainable marine aquaculture industry in Indonesia. This is important because, as an archipelago, Indonesia is expected to play a significant role in providing food supplies from marine aquaculture. The results are from a case study in Situbondo, East Java in which the hydrodynamics and sedimentation are simulated using the Delft3D model with an energy-loss coefficient included in the model to account for floating cages.
