Notes:
From the Gong-Shy-Tyan (GST) Stream and the Tanshui River, Taiwan, eels ranged from 5.53 cm t.l. (elvers) to 72.5 cm t.l. Anguilla japonica accounted for 93-99%, A. marmorata 1-7% and A. bicolor pacifica less than 1% of all eels caught. Mean eel lengths increased from 10 cm t.l. at the downstream sites to 50 cm t.l. at the upstream sites. Females made up 92.8% of the sex-determined eels. Population density, averaged approximately 0.14 eel m−2 (2.42 g m−2) and 0.25 eel m−2 (0.92 g m−2) in downstream sites of the GST and Tanshui River, respectively, and decreased substantially with upstream distance. Eels were rarely found in the heavily polluted and dam constructed areas in the midstream site of the Tanshui River.
