Seaweed farming at Nusa Lembongan, Bali

The Balinese population of 3.0 million (1.5% of Indonesia's population) live mostly on the island of Bali, making up 89% of the island's population. There are also significant populations on the island of Lombok, and in the eastern-most regions of Java (e.g. the Municipality of Banyuwangi). It is the most populous Hindu majority island in the world.

Mariculture is a specialized branch of aquaculture involving the cultivation of marine organisms for food and other products in the open ocean, an enclosed section of the ocean, or in tanks, ponds or raceways which are filled with seawater. An example of the latter is the farming of marine fish, including finfish and shellfish e.g.prawns, or oysters and seaweed in saltwater ponds. Non-food products produced by mariculture include: fish meal, nutrient agar, jewellery (e.g. cultured pearls), and cosmetics.

Bali is an Indonesian island located in the westernmost end of the Lesser Sunda Islands, lying between Java to the west and Lombok to the east. It is one of the country's 33 provinces with the provincial capital at Denpasar towards the south of the island (strictly speaking, the province covers a few small neighbouring islands as well as the isle of Bali).

With a population recorded as 3,891,000 in the 2010 census, the island is home to most of Indonesia's small Hindu minority. In the 2000 census about 92.29% of Bali's population adhered to Balinese Hinduism while most of the remainder follow Islam. It is also the largest tourist destination in the country and is renowned for its highly developed arts, including traditional and modern dance, sculpture, painting, leather, metalworking, and music. Bali, a tourist haven for decades, has seen a further surge in tourist numbers in recent years.

The population of Indonesia according to the 2010 national census is 237.6 million, with 58% living on the island of Java, the world's most populous island.

Despite a fairly effective family planning program that has been in place since the 1960s, the population is expected to grow to around 254 million by 2020 and 288 million by 2050, falling to sixth behind Pakistan and Brazil sometime before 2050.

Indonesia includes numerous ethnic, cultural and linguistic groups, some of which are related to each other. Since independence, Indonesian (a form of Malay and official national language) is the language of most written communication, education, government, and business. Many local ethnic languages are the first language of most Indonesians and still important.

Seaweed farming is the practice of cultivating and harvesting seaweed. In its simplest form, it consists of the management of naturally found batches. In its most advanced form, it consists of fully controlling the life cycle of the algae. The main food species grown by aquaculture in Japan, China and Korea include Gelidium, Pterocladia, Porphyra, and Laminaria. Seaweed farming has frequently been developed as an alternative to improve economic conditions and to reduce fishing pressure and over exploited fisheries. Seaweeds have been harvested throughout the world as a food source as well as an export commodity for production of agar and carrageenan products.
