The present study aimed to investigate the morphomatric traits of small indigenous fish (SIF) species, Channa punctata, Mystus vittatus, Notopterus notopterus, Puntius sophore, Labeo rohita from low and mid altitude regions from north east, India. A total of 50 specimens from each species were collected between March 2023 and May 2024. Fourteen morphometric parameters were chosen for a comparative analysis of the fish species from the two distinct regions. In the low-altitude region, the average lengths recorded for C. punctata, M. vittatus, N. notopterus, P. sophore and L. rohita were 15.06, 10.22, 19.22, 9.69, and 21.79cm, respectively. The corresponding average weights for the fish species were 44.22 for C. punctata, 12.27 for M. vittatus, 62.45 for N. notopterus, 12.38 for P. sophore and 175.95g for L. rohita. In the mid-altitude region, the average lengths for C. punctata, M. vittatus, N. notopterus, P. sophore and L. rohita were 17.41, 12.71, 20.21, 11.81 and 24.98cm, respectively. The average weights recorded for the fish species were 42.54 for C. punctata, 12.42 for M. vittatus, 62.2 for N. notopterus, 12.53 for P. sophore and 176.28g for L. rohita. M. vittatus, L. rohita exhibited positive allometry growth in both low and mid altitude region while C. punctatus, N. notopterus exhibited negative allometry growth in both regions. P. sophore is found to be exceptional indicating positive allometry growth in mid-altitude region and negative allometry growth in low- altitude region. |
