Progress Report on the Artificial Glass Eel Production in Korea for the Last Ten Years

This review will summarize a decade of aquaculture and allied stream research conducted to develop the artificial production of glass eel, Anguilla japonica in the Rep. of Korea. After a series of efforts, Korea got the breakthrough to produce two individual glass eel 2^nd time in October, 2012 after Japan in 1973 in the world. Other Korean scientists found that by rearing the Eel for a period of 3 months, maturation and vitellogenesis process can be shortened as well as the efficiency of salmon pituitary extract (SPE) injection could be significantly improved. In their another study, it was demonstrated that artificial maturation could be successful only during May (spring) to January (winter) when female brood stock eel (400-600g) were subjected to intramuscular injection of SPE (20 mg/fish) by weekly. Among other phenomenal Eel research, the final maturation in female eel was found to be induced through intraperitoneal administration of Freund’s incomplete adjuvant containing SPE (20 mg pituitary powder/fish) using water-in-oil (W/O) type emulsion. Likewise, several other phenomenal research conducted by Korean scientists to produce the artificial glass eel including the nutritional research on broodstock will be reviewed and discussed.
