Mangrove vegetation supports milkfish production in silvofishery pond

Abstract

The present study reports mangrove vegetation to support the milkfish (Chanos chanos) production in the silvofishery pond. This study aimed to determine the relationship between the densities of mangrove vegetation on C. chanos cultivation in a silvofishery pond and to determine the factors that influence milkfish production. 10,000 milkfish fries with a size of 3-4 cm were cultivated for six months in the silvofishery pond on sapling and seedling density based. The collection of milkfish production data was observed when harvesting was carried out. There are three mangrove vegetation inside the pond detected, including Rhizophora apiculata, R. mucronata, and Avicennia marina. Average water temperature measured in sapling dominance pond was 29-31.5 °C and seedling dominance pond 2 was 3031.5 °C. The density of mangrove sapling domination was 870 individual, 265 fish average weight of 147.4 g/milkfish yielding 39.1 kg while on seedling dominance has a density of mangrove of 695 individuals, with the level of fish was 436, average fish weight 95 g/milkfish yielded 41.4 kg. This research provided consideration for decision makers in implementing sustainable mangrove management policies.
