Non-lethal Detection of Skin Injuries in Juvenile Chinook Salmon Oncorhynchus tshawytscha by Fast Green FCF Dye

In fish, as in humans, an intact epidermis is critical to defense against entry of pathogens into the skin. Macroscopic examination of scale loss is the principal method of evaluating physical damage to juvenile salmonids out-migrating through hydroelectric dams in the Snake and Columbia Rivers, and in fish subjected to capture and handling procedures in locations such as hatcheries, fish...
