There has been interest in raising native predator fish species because of their enormous potential for aquaculture. A description of the length-weight relationship for 60 wild and 120 cultivated Channa striatus is also included. It is determined that the fish species did not experience weight increases greater than the cube of their total lengths if the length coefficient values in the length-weight relationship are static. There was a substantial (p<0.05) difference in the length between the wild C. striatus from Nagercoil and the wild C. straitus from Melapalayam (43.3 cm). There was a remarkable (p<0.05) difference found between the wild C. striatus from Melapalayam (651.5 gm) and the wild C. striatus from Nagercoil. The present study will find the baseline data on the length-weight connection for Channa striatus provided by this study relevant in the future.
