In the inland waters of Phu Yen, three species of eels of the genus Anguilla have been identified, that are Anguilla marmorata Quoy & Gaimard, 1824; Anguilla malgumora Kaup, 1856 and Anguilla bicolor McClelland, 1884.

The highest fishing yield with CPUE of seine net is 0.25±0.01 – 1.2±0.4kg/ 1 fishing gear/day and bag-net is 0.2±0.05 – 0.9±0.2 kg/ 1 fishing gear/day, the lowest is dipnet and tree branch bag from 0.03±0.04 – 0.2±0.01 kg/1 fishing gear/day. The population of flower eels has the largest number and distributed throughout the water bodies accounting for over 95%, the ebony eels are distributed in the Ba river, Ky Lo river, Hao Son resevoir and Ban Thach river with a small number and The sharp eel is only found distributed in Ky Lo and Ba rivers, not distributed in the remaining water bodies, the number of these two species decreases. The catch yeild of 3 species of eel in the dry season is 4,235 tons and in the rainy season 9,801 tons, an average 14,03 tons/year.
