Indonesia, a coastal gem abundant in marine resources, has a rich history of traditional fish and shrimp farming. However, the conversion of mangrove ecosystems for aquaculture has triggered ecological concerns. The depletion of fish and shrimp quality, coastal erosion, and seawater intrusion have become prevalent issues, prompting innovative solutions for sustainable aquaculture.
In response to these challenges, Prof. Dr. Esti H. Hardi, a distinguished professor at the Faculty of Fisheries and Marine Sciences at Mulawarman University, initiated the Kedaireka program. This collaborative effort with the Peat and Mangrove Restoration Agency (BRGM) aims to introduce “smart Silvofishery” in the Delta Mahakam area, an eco-friendly approach to aquaculture.
Smart silvofishery is a pioneering aquaculture management method that prioritizes mangrove ecosystem restoration while maximizing pond productivity and economic value. This method involves polyculture, cultivating various species like shrimp, fish, crabs, and seaweed concurrently in one pond over a specific period. Mangroves are strategically planted within the ponds, offering a holistic approach to environmental sustainability and economic viability.
Research findings reveal that smart Silvofishery yields boast higher amino acid, fatty acid, and protein content compared to conventional aquaculture methods. The Salo Sumbala group in Muara Badak Ilir Village, Samarinda, East Kalimantan, serves as a successful example of a community embracing smart Silvofishery. Initially met with skepticism, the group is now actively involved in educating others about the benefits and techniques of this innovative approach.
Ramlan, the group’s chairman, shared his transformative experience with the Silvofishery system in his pond. “I noticed pond embankment erosion due to tidal fluctuations. Planting mangroves along the embankment prevented erosion. After smart Silvofishery training, I replanted mangroves in the pond, resulting in increased harvests in quantity and fish quality. The fish were fresher, and after sharing my success, other farmers adopted the system,” explained Ramlan.
Despite initial skepticism, Ramlan’s persistence led to a ripple effect, with local farmers adopting smart Silvofishery practices. This newfound approach enables communities like Muara Badak Ilir Village to independently manage their pond areas, significantly increasing income. The harvested fish are processed into valuable products like boneless fish and traditional East Kalimantan crackers, creating new market opportunities.
Feri, a local youth in Muara Badak Ilir Village, highlighted the positive impact of the smart Silvofishery system on the community. “The Fishermen’s Children Association was formed to improve aquaculture outcomes through mangrove rehabilitation. The community now recognizes the benefits of mangroves in ponds, leading to increased harvests and a growing sense of community awareness,” shared Feri.
The Smart Silvofishery model not only addresses environmental concerns but also empowers coastal communities, offering a sustainable and economically viable solution for the future of aquaculture in Indonesia.
