Mapping Ocean Wealth – Indonesia

Tuna fishermen in IndonesiaIn support of The Nature Conservancy’s Global Mapping Ocean Wealth (MOW) Program, PT Hatfield Indonesia is collaborating with scientists from the Agricultural Institute Bogor (IPB) to generate data that will be used by decision makers in marine spatial planning and sectoral management programs such as fisheries.

Indonesia lies at the nexus of the Pacific and Indian Oceans where strong ocean currents collide among a complex mosiac of islands and archipelagos, creating a dramatic upwelling of nutrients that support vast stocks of commercially-important species of tuna such as skipjack, yellowfin, bigeye, albacore, and southern Bluefin. As a result, Indonesia harvests 15 percent of the world’s skipjack tuna and over a quarter of the large valuable tunas (yellowfin, bigeye, albacore, and southern Bluefin tuna combined) caught in the Western and Central Pacific Fisheries Council region, and has one of the largest fleets operating in the Indian Ocean. Due to the dynamic nature of this region, Indonesia’s waters provide a wealth of ecosystem services to surrounding nations, where tuna fleets from across the region target adult tunas that were born and raised within Indonesian boundaries.

PT Hatfield Indonesia employs cutting-edge, cost-effective methods to identify and model spatial patterns in tuna distribution and productivity – a critical link in mapping ocean-scale pelagic habitat features in the Lesser Sunda Eco-region. Specifically, by mapping pelagic habitat features together with fisheries utilization patterns, and combining these data with catch-composition information, highly valuable recommendations are provided to managers in support of ecosystem-based tuna fisheries. This information also facilitates compliance with national and international policies and conventions, a critical step in sustainable tuna management in Southeast Asia.
