Abstract: The carcass traits and commercial characteristics of farmed freshwater Oreochromis niloticus and Puntius gonionotus were investigated to calculate yield data useful for programming semi- automated processing units. Specimens with average weight of 819.5±42.3 and 2108±38.2 were collected from both tilapia and puntius respectively. Samples were taken from culture pond of the Central Institute of Freshwater Aquaculture (CIFA), Bhubaneswar, Odisha, India. Carcass offal yields as well as carcass curability were evaluated. Head yields were recorded as 27.1 and 10.07% for tilapia and puntius, respectively. The gutted yield, headless yield skinless dressed round percentage were determined as 80.0, 53.0 and 51.6% for tilapia and 62.9, 52.20 and 50.1% for Puntius respectively. The meat: bone ratio in filleting average 2.1 for tilapia and 4.2 for silver carp. The middle cut of tilapia and puntius had both the highest total yield percentage and highest meat yield. The hind cut of tilapia had significantly higher yield percentage and meat yield in comparison to puntius. In both tilapia and puntius dry matter, ether extract and protein percentage were highest in the middle cut followed by fore cut and hind cut. In puntius the percentage of fat content was found to be significantly higher than in tilapia. The omental fatin puntius was significantly higher than tilapia.
