SUSTAINABILITY ANALYSIS OF MILKFISH AQUABUSINESS MANAGEMENT ON SUMBAWA ISLAND: A BIOECOLOGY, TECHNOLOGY, AND ECONOMIC APPROACH

Abstract

For more than three decades, the coastal communities have managed and utilized the coastal land of Sumbawa Island for milkfish (Chanos chanos) cultivation. They carry out the activities in ponds making the most of the tides and the coastal land topography. The choice of milkfish is due to the community fondness, euryhaline organisms, use of simple technology for aquaculturing, low cost, and high survival rate. The research objective is to find out the status of sustainability management of the dimensions of bioecology, technology, and economic as well to find out the sensitive attributes of each dimension. Sustainability is a mandate in the management of global and Indonesian fisheries. This research was conducted in three regencies (Sumbawa, Dompu, Bima) from June to October 2018. The data collection employed the method of dependent-survey and the techniques comprised sampling, dialogue, observation, and documentation. The data processing of the whole attributes employed various statistical and non-statistical equations. The sustainability analysis of the management dimensions made use of the technique of Rapid Appraisal (RAP) for milkfish aquabusiness (Rapmilkfish). The Rapmilkfish Analysis results that the sustainability status of the dimension of bioecology is ‘Sustainable’, technology is ‘Quite Sustainable, economic is ‘Less Sustainable’, and the number of sensitive attribute is 12 attributes. This research conclude that application level of milkfish aquaculture technology is classified as environmentally friendly and positively correlated to the sustainability of natural resources. Therefore, the milkfish aquaculture activities can be continued without having to bring up the level of milkfish aquaculture technology in an effort to raise pond productivity.
