| Abstract | This study provides new data on the developmental morphology for the identificationof three species of fish found in Thailand, stone-lapping minnows (Garra cambodgiensis), sooty garra(G. fuliginosa), and Tenassarim garra (G. notata). Larval specimens were collected from theartificial breeding tanks and rearing ponds at the Mae Hong Son and Nan Fisheries Research Stations.The larvae were divided into four developmental stages, i.e., yolk sac, larval, post-larval, and juvenile.Their morphometric and meristic characteristics, including the number of myomere, dorsal-andanal-fin rays, and the chromatophore pigment patterns, were studied and used for the speciesidentification. For the Garra larvae, the chromatophore pigmentation on the gut, midline, and dorsaland ventral parts of the body were the important characteristics. In addition, the juvenile stage can bedistinguished by the chromatophore pigmentation on the gut, midline, and the dorsal and ventral partsof the body. |
