CWD resistant rainbow trout
Female rainbow trout (Oncorhynchus mykiss) from a group that have been selectively bred for resistance to bacterial cold-water disease (CWD). CWD is caused by the bacteria Flavobacterium psychrophilum. It causes tissue erosion and ulceration, and can be fatal. This fish is from a line known as ARS-Fp-R, which has been bred for a heritable resistance to this disease. Selective breeding in this manner is common in farming, where diseases tend to spread rapidly due to crowded conditions., by Stephen Ausmus, US DEPARTMENT OF AGRICULTURE/SCIENCE PHOTO LIBRARY
