ABSTRACT
In a second study of electromicroscopic analysis of ultrastructural organelles of coho
salmon muscle showed a significant increase in lipid droplet density in the largest stages
compared with the smallest fish. The opposite was observed with the mitochondria where
its density decreased in the large sized fish. An apparent decrease in capillary density with
increasing body mass was also observed. These finding may imply a possible additional
role of lipid depot as fish grew from parr to smolt.
