Abstract

Eighty pond loach Misgurnus anguillicaudatus specimens were collected in An Đông Ward, Hue City. The specimens were weighed and sized; the morphological features were described and compared between males and females. Twenty-six morphological features and thirty-four morphological ratios were determined. Twenty-five morphometric ratios were found to be statistically different between male and female fish, of which twenty-three ratios of the female loaches were higher, and two ratios were lower. The average number of spines on the dorsal fin, pectoral fin, pelvic fin, anal fin, and caudal fin is 2, 2.01, 2, 2, and 2 + 2, respectively; the average number of rays on the dorsal fin, pectoral fin, pelvic fin, anal fin, and caudal fin is 7, 8.19, 5.98, 6, and 8 + 8, respectively. The length/body weight exhibits a strong correlation (R2 = 0.7486).
