The process of extracting fish protein concentrate from Harengula zunasi with the Soviet device and acidic organic solvent was studied. Fish meat of H. zunasi is an resource of protein because of its high protein content being. 77. 0%, adipose 15. 1% and ash 7. 2%. The optimal conditions for processing fish protein concentrate (FPC) from H. zunasi included citric acidified alcohol as solvent to extract the ground dry fish meat of 40-eyelet meshed for 4 hrs. The amount of organic solvent used for extraction was 7 .5 times as high as that of fish meat. A high quality of FPC was obtained with 89. 6% in protein and 0.07% in fat.
