Abstract

Silvofishery systems represent an integrated coastal management approach that facilitates sustainable development by preserving mangrove ecosystems while establishing environmentally compatible aquaculture industries that enhance community economic development and food security. This study examines the productivity and water quality parameters of silvofishery ponds in Alur Dua Baru Village, Sei Lepan Subdistrict, Langkat Regency, North Sumatra, Indonesia. A comprehensive water quality assessment was conducted using in-situ sampling techniques, measuring critical parameters such as temperature, dissolved oxygen concentration, salinity, and pH levels. Results demonstrate that water quality parameters remained within acceptable ranges for the cultivation of target species, specifically mangrove crabs (Scylla sp.), giant tiger prawns (Penaeus monodon), and milkfish (Chanos chanos). However, temporal variations in water quality were observed throughout the monitoring period, with optimal conditions recorded during the initial month, followed by a deterioration in the final observation period. These fluctuations were attributed to multiple environmental factors, including hydrological variables such as precipitation patterns, solar radiation intensity, temperature variations, and tidal cycles, as well as biological factors related to increased oxygen demand from growing aquaculture species, resulting in declining dissolved oxygen concentrations. Recommended management strategies include implementing controlled gate operations during high tidal periods to maintain optimal pond conditions. The silvofishery implementation yielded significant increases in harvest productivity, with recorded yields of 300 kg of milkfish, 200 kg of giant tiger prawns, and 80 kg of mangrove crabs. These findings indicate that silvofishery systems can significantly enhance pond productivity while providing viable opportunities for sustainable and environmentally responsible aquaculture businesses in coastal communities.
