Summary The carcass and commercial yield traits of Channa striatus were evaluated. Experimental fish were 8‐month‐old snakehead murrels ( Channa striatus ) weighing 500–700 gm, reared in earthen ponds and cultivated intensively at a rate of 10 000 fingerlings/ha. The fish were given formulated feed for a period of 1 year. Morphometric parameters were measured along with carcass, filleting, and offal traits. The murrel head yield (28.7%) as well as scales and skin yield (11.92%) were recorded. Dressed murrel (evisceration yield) was 89.59% of the live weight. Dressed percentage (minus the head, skin and viscera) was 50.72%. Average meat‐to‐bone filleting ratio was 3.43 of marketable size murrels. Insignificant accumulations of fat deposits on the lining of the abdominal cavity and coating the bowels were noted.
