description
I am working at KWS (Kenya Wildlife Service) in Malindi, as a volunteer of JICA. My job is teacher of environment. This presentation is about ells. People never saw ells before and hate its style, because it looks like snake. So I provided information about ell families, Japanese cultural food of ell, and scientific result, which recently found are included. If we succeed to reproduce ell by ourselves, there is much potential for new business.

How researcher found out?
• In 2009, Jap. researcher established new technique to indicate location of species among the ecological pyramid.
• Research 2 kinds of amino acid and compare ratio, researchers can find out what are they eating.
• In 2010, Japanese governmental org. succeeded to 100% cultivation of ell. This is first time in the world.
Current Problem
• To cultivate ell, required natural ell.• But, amount of fishery shrieked 1/10. • Succeeded to raise from egg, first time in
the world, but found difficulty to grow them up, due to feeding.
• Circulation of fresh sea water is required. Otherwise they will die.
• Also, once put feed into aquarium, bacteria increase.
Conclusion: In the future• Not only Japanese Ell, but also other kinds
of ell may be succeed to become domestic.
• Ell consumed by many people in Asia, and also Europe, due to Japanese culture increased popularity, such as Anime, AKB, and Japanese healthy food. So demand will increase.
• That will be huge potential of ell business.
