In summer 2022, Michigan State University Extension educators Lauren Jescovitch and Elliot Nelson went on an adventure of a lifetime to Indonesia. Earlier in the spring, Jescovitch was named a 2022 Michigan State University College of Agriculture and Natural Resources (CANR) Global Scholar, an award that provides early- and mid-career MSU employees with seed money to strengthen and expand their global networks and collaborations. The Global Scholar award enabled Jescovitch and Nelson, both Michigan Sea Grant educators, to spend 14 days in Indonesia. Their funded project, “Aquaculture Education: Swimming from Great Lakes to Great Seas,” aims to develop collaborations and key relationships to enhance MSU Extension with global networks in the aquaculture community.

Indonesia is currently the world’s second-largest producer of aquaculture, or farm-raised aquatic products (e.g., fish, shellfish, lobsters, seaweed, etc), with a total production of 15.9 million metric tons, according to the Food and Agriculture Organization (FAO). The United States is the 18th-largest aquaculture producer in the world, with 0.5 million metric tons. Indonesians also consume a lot more nutrient-rich seafood, at a rate of 43.9 pounds per person per year. U.S. residents consume 11.0 pounds per person each year, less than the recommended intake of 26.0 pounds per year.

Unique partnerships possible

Therefore, partnerships in Indonesia could provide optimal case studies of high production aquaculture systems and an aquaculture-literate society accepting of farming in the water. In return, we in the U.S. could provide examples of sustainable practices and seafood consumer safety programs, thus bringing together a very unique partnership.

Jescovitch and Nelson explored many kinds of aquaculture while visiting Indonesia. They were welcomed and hosted by Jakarta Technological University of Fisheries, where Jescovitch presented as a keynote speaker at the National Blue Economy Conference and Trade Exhibition.

After training aquaculture students to use 360-degree cameras and virtual reality technology, Nelson and Jescovitch took their own camera to Bogor and Serang, two cities on the island of Java, where they toured many types of freshwater and saltwater aquaculture farms and research facilities. Then they flew east to Lombok and toured several farms and on-going research projects. Along the way, they captured 360-degree video footage to create virtual tours of the sites.

An abundance of aquaculture

Jescovitch and Nelson saw many different types of systems, species, and end-uses of aquaculture products. The largest end-use was food (or seafood) which included shrimp, lobster, seaweed, algae, pompano, barramundi, grouper, catfish, and more! The next-largest use was ornamental or pet fish, which included breeding of freshwater fishes like knife fish and arowana, and projects that were researching saltwater species like clownfish and blue tangs. Some of the more intricate systems for food products included a mangrove-shrimp pond system that supported ecotourism activities, and a zero waste, sustainable aquaculture system.

Others showcased the difference between net pen systems and cage systems and the variations of their use. Many open-water floating cages held what was known as “the miracle of Lombok,” or lobsters. In these systems, pearl and sand lobsters are cultivated from babies via in-home hatchery systems and grown out in the bay in cages until harvested and packaged for export. Many families and communities clearly depended on these many different seafood supply chains as food security and a way of life.
