Fatty acids composition of the iced preserved Wallogo attu of river Brahmaputra and its tributaries

Wallogo attu, an important catfish species found available in the rivers of Brahmaputra and its tributaries is having highly demand among the consumers. Though the species is found throughout the year in the markets but in the months from November up to March every year the catch reaches the peak with surplus amount. So there is a need for the preservation of the species with high food value. The flesh of Wallogo attu contains high amount of proteins along with fats. In the present study, an attempt has been made to study the changes of fatty acids during different conditions of ice preservation.
