Analysis of the Influence of Pond Design on the Efficiency of Residual Feed Disposal in Inland Fisheries Farming Ponds

Abstract

Failure in inland fisheries farming with artificial pond mechanisms made of tarpaulin is closely related to water quality issues. Water problems contaminated with dirt, temperature, and acidity levels trigger mass fish deaths. One source of water pollution is the sediment of uneaten feed by fish, which has been at the bottom of the pond for too long. Removing sediment periodically, accurately, and quickly can maintain water quality and reduce production costs for adding replacement water to the pond that is wasted with sediment. This study aims to determine the effect of variations in pond design on the hydrodynamic behaviour of pond flow, which affects the rate of disposal of uneaten feed by fish. The study used the Computational Fluid Dynamics (CFD) simulation method using ANSYS 2023 R2 software. The simulation used data of 20 grams, or 8186 pieces, of fish feed pellet particles injected through the water surface, and its movement was observed for 100 seconds. The slope of the pond bottom in this simulation was varied between 0o, 4o, 8o, and 12o with circular pond geometry. The simulation results show that the slope of the pond bottom affects the hydrodynamic behaviour of pond flow and the fish feed pellet particle removal rate, where a slope of 12° shows the best results.
