Sampling locations and species composition by country
Green dots indicate the cities where eel samples were collected. The pie charts show the species composition in 11 countries/regions: [Navy blue] American eel, [Green] European eel, [Red] Japanese eel, [Light blue] Indonesian shortfin eel. European eels were detected only in Japan and China, while Indonesian shortfin eels were found only in Hong Kong. The “Whole samples” chart in the lower left shows the simple species composition without weighting by distribution volume.
The reason why European eels were not detected in Europe is that only products prepared in the Japanese style, such as sushi and kabayaki, were sampled. This sampling bias was mitigated by assuming that eel production in countries where European eels are distributed consisted of European eel, and incorporating this assumption into the subsequent calculations.
