The Effort to Maintain Mangrove Forest through the Development of Silvofishery Pond

Abstract

The objective of this study was to find out the perception and utilization of mangrove forest by the sylvofishery fish farmers to maintain mangrove ecosystem in Desa Tanjung Rejo, Sub-district Percut Sei Tuan, Deli Serdang Regency. The study was conducted through questionnaires and field observations on twenty-two ponds populations that have been applied silvofishery model in Desa Tanjung Rejo, Sub District Percut Sei Tuan, Deli Serdang Regency. The method used in this study was descriptive analysis with a qualitative approach. The results of a study on the effort to maintain mangrove forest through the development of sylvofishery pond showed that fish farmers' perception about the function of mangrove forest has average 90% and the utilization of mangrove forest, which existed in their pond, has average 80%. Furthermore, on the management of mangrove forest, sylvofishery farmers were involved together to protect and evaluate the mangrove.

Silvofishery: In What Mangrove Coverage Condition Can this System Provide Benefits for the Community?

“…More phytoplankton leads to more organisms performing photosynthesis; therefore, more oxygen is produced, and the source of food for aquatic biota increases. Furthermore, others confirmed [19] that the mangroves in and around silvofishery ponds serve as a support that binds the soil sediment and strengthens the soil elements, so when the current moves in from the sea or when the tide comes in, the sediment is not easily disturbed, and the land is protected from erosion and abrasion. Thus, the presence of mangroves in the ponds enables an increased production of the ponds while maintaining their infrastructure, resulting in a significant financial impact on the aquaculture business [20].…”
