摘      要：A simple yet useful criterion based on external markings and/or number of dorsal spines is currently used to differentiate two congeneric archer fish species Toxotes chatareus and Toxotes *** we investigate other morphometric and meristic characters that can also be used to differentiate these two *** component and/or discriminant functions revealed that meristic characters were highly correlated with pectoral fin ray count,number of lateral line scales,as well as number of anal fin *** results indicate that *** can be distinguished from *** by having a greater number of lateral line scales,a lower number of pectoral fin rays,and a higher number of anal fin *** contrast,morphometric discriminant analyses gave relatively low distinction:76.1% of fish were ascribed to the correct species *** observed morphometric differences came from the dorsal and anal spines lengths,with *** having shorter dorsal and longer anal spines than ***,meristic traits were more useful than morphometrics in differentiating the two species;nevertheless,meristics and morphometrics together provide information about the morphological differentiation between these two closely related archer fishes.
