Abstract

This study assessed the effects of different processing techniques on proximate compositions of exotic fish species Tilapia (Oreochromis niloticus) and indigenous fish species Rohu (Labeo rohita) and Mori (Cirrhinus miragla). Total 109 specimens were collected from earthen fish ponds located in Fisheries and Aquaculture Department at Ravi Campus Pattoki, Lahore, Pakistan. The size of specimens belonging to tilapia was 200 g approximately while the weight of specimens of rohu and mori was approximately 1 kg. Fish products were developed by different preservation methods like drying, freezing, smoking and salting. The developed products were subjected to chemical analysis for nutrients. Two samples of each species were used to determine nutritional properties of the raw fish which was used as control group.
