DEVELOPMENT OF MANGROVE CRAB (Scylla sp) CULTIVATION SILVOFISHERY SYSTEM TO CONSERVE MANGROVE FOREST IN MERANTI ISLANDS REGENCY, RIAU PROVINCE

Abstract

Mangrove forest is one of the coastal ecosystems were plays a role in supporting marine life. Existence of mangrove forests in the Meranti Kepulauan district is experiencing degradation which has implications for the decline to ecological, social and economic functions of the local community. The efforts for minimize damage of mangrove forests have been carried out by local governments and local communities. One of the effort could be done through the cultivation of mud crabs with sylvofishery system. Experiment method was applied and interview was done in Teluk Belitung and Bandul villages, Meranti Regency. Data and information were collected and had been analyzed and activities reported that related to mud crab culture using the silvofishery system. The resut of the study showed that potential development of marine culture in the Kepulauan Meranti district is spread across several islands such as Padang Island, Tebing Tinggi and Pulau Rangsang with an area of 438 ha. The extent of the aquaculture site is also supported by good waters quality and suitable for developing mud crab culture with the sylvofishery system. The trial application of the mud crab silvofishery model of fixed confinement obtained a survival rate of up to 70% and an average growth of around 100-140 g per month. Maintenance of mangrove crabs with the sylvofishery system for 3 months can provide benefits and additional income per month of IDR. 1,070,150. In one cycle of enlargement if normal conditions, it’s can return the investment so the mangrove crab sylvofishery deserves to be an alternative effort for coastal communities.
