CommentsThe Oregon Invasive Species Hotline received a report from an angler on mitten crabs over the weekend. I spoke with him and the individual was very knowledgeable about the Columbia River and crabs in general (he is an avid angler and crabber). He reported that he was fishing with herring near Kalama on the Washington side of Sandy Island on March 23rd. He reeled in his line and a crab was attached. He said it came out of the water a couple inches and then dropped off. The crab looked like it had stuff growing on it. He said that he had caught dungeness crabs in the river before, but that this one was a bit different. Over the weekend he saw one of our mitten crab signs at a boat ramp on Sauvies Isl. and recognized the crab pictured on the sign as the one he caught in March. The crab was about 2.5 inches carapace width.
