Eel is a commodity that has a high value of about 12-15 US $ / kg of live eels and preferably international markets (Ringuet 2002). World eel production in 2000 reached 200,000 tons worth US $ 300 million, – and in 2010 reached 250,000 tons (FAO 2013). Countries like Japan, Korea, China, Hong Kong, Germany, Italy, and America is an eel consumer so that export commodity potential of eel is very high (Affandi 2005). Japan imported eel in 1999 amounted to 65 tons and increased in 2001 to 85 tons (Ringuet 2002). This is certainly a proof that eel is a potentially lucrative export commodity. Eel has good taste and high nutritional content. Suitha (2008) states eel meat contains vitamins A, EPA, and DHA is quite high compared with other food ingredients (See Table 1).
Table 1. Nutritional Content of Fish eel (Suitha 2008)
|Bahan Makanan||Kandungan Vitamin A (IU/100 g)||Kandungan EPA (mg/100 g)||Kandungan DHA (mg/100 g)|
|Daging ikan sidat||4.700||1337||742|
|Hati ikan sidat||15.000||–||–|
The content of EPA and DHA in foods is a very good nutritions in the process of child development, especially brain development. DHA benefits include helping the growth of the brain and nerve fibers and visual function in the first 6 months of life. In adults, DHA also helps the brain in learning ability. In addition, DHA is beneficial in reducing the risk of heart disease. Another benefit of DHA is to prevent accumulation of plaque on the walls of blood vessels by bad fats, thus reducing the risk of heart disease and stroke. In addition, DHA also helps prevent cancer and slow the aging process (Tasse, 2010). This course will have a positive impact on children who are given these fish food intake, which is expected to grow smart kids who will continue the struggle to build the largest moslem country in the world.

European countries such as Germany, Denmark, the Netherlands and the East Asian countries such as Japan, Taiwan, China and South Korea are a very high consumer and producer of eel. Nutrients beneficial to health and high prices become the biggest attraction for developed countries exploit massive eels in their country. Massive exploitation led to over fishing (difficult to get fish resources) and rare plus reproductive technologies and maintenance of larvae do not develop properly, resulting in such countries a decline in catchment and the fish production.

Indonesia has at least 6 species of eels in the territorial waters of which Anguilla marmorata, A. celebelencis, A. acentralis, A. borneensis, bicolor bicolor, and the bicolor pacifica (Affandi, 2005). Indonesia has a diversity of eel as well as the largest number in the world, it is certainly a motivation and a large capital to be able to manage these resources properly.
Table 2. Classification, zoning and geographic distribution of eel (Tomiyama and Hibya, 1977)
Maps depicting the distribution along the sea of eel in Indonesian waters. Eel’s potential is quite large and has not been utilized optimally. Surely utilization of natural resources and the environment and also mastery reproductive technology continues to be explored and practiced so that the availability of eels in Indonesia can be maintained. Surely these efforts require the cooperation of various parties, ranging from governments and communities to realize sustainability in Indonesian eel.

From this background would be a great opportunity for Indonesia to be able to develop fish farming production, then we PT. LAJU BANYU SEMESTA (LABAS) build an integrated eel aquaculture industry that contributes to the production and preservation of eels in Indonesia, which will be used to build Indonesian society. InshaAllah.
