Sea-eels caught by fishing boat and trawl were analyzed to investigate feeding status and individual growth of sea-eels caught from the lost plastic sea-eel Pot which is estimated at the ghost fishing Average length of sea-eel caught from fishing boat and test fishing was 33.6cm, 48.9cm for trawl and 45.6cm for the lost plastic sea-eel pot, respectively. The length frequency distribution is the same as the fact that sea-eel goes to the offshore from the coastal waters according to the getting growth. Sea-eel rate having empty stomach were 5.0% for fishing boat, 4.2% for trawl and the empty stomach rate of sea-eel was the highest as 87.6% in the lost pot. Sea-eel rate feeding fish as prey were 98.7% for fishing boat, 78.8% for trawl and 63.3% for the lost pot, respectively and other preys were crustacean and cephalopod. Fatness index calculated using weight and length were 1.514 for trawl catches and 1.292 for the lost pot and the difference was 15% between trawl catches and the lost pot. There also was difference at the 5% significance level in the result of t-test of Covariance Analysis.
