Abstract

Morphometric and meristic characteristics of Clupisoma naziri was explored in Gomati River Tripura and the poorly known C. naziri, was newly recorded from the river at 23°33.144’N, 91°36.732’ E,  elevation 39 m and 23°31.676’N, 91°39.184’ E, elevation 30m. Morphometric measurements (8 Male and 4 female) show the mean length and weight of the fish is 29.3±3.4cm and 246 ±7.1g respectively. Meristic counts show 40–45 anal-fin rays which is one of the important distinguishing characters of the species. The average water pH of the sampling site observed 6.7–7.2. Dissolved oxygen observed 5.6–6.4 mg/l, Total alkalinity 55–56 mg/l and Transparency observed 15–25 cm.

Graphical Abstract

Clupisoma naziri is currently considered near threatened by IUCN criteria, and therefore, it is urgent to take conservation measures and to study biological parameters of the fish to protect the fish in nature as well as in culture.
