Update: Ottawa River Catfish Kill

The Ontario Ministry of Natural Resources has released its findings on this summer's catfish kill on the Ottawa River. The report supports the Ministry's earlier conclusion that the columnaris bacteria flourished in oxygen-deprived shallow water, killing between 2,000 and 4,000 juvenile channel catfish which tend to feed near shore. The authors are optimistic that, with only 2-3% of the channel cat population affected by the kill, the long-term health of this fishery is unaffected.
