Above: The Assabet River, just below the Pine Street bridge in Concord, Mass., on 15 Nov. 2014
Tonight, my father’s brother Lee, and my cousins Lynn and Steve came up to visit Dad. Uncle Lee spent his career as a chemist, but I would be more likely to call him a practical icthyologist; he knows as much about the biology of fish as anyone else I know; he raises something on the order of a hundred different species of fish in his basement, and he’s an avid fisherman of wide experience. For her part, my cousin Lynn works for MassWildlife as a habitat protection specialist, and has a wide knowledge of many different Massachusetts ecosystems, including rivers, streams, and ponds.
As we were eating our dinner (we had fish, of course), Uncle Lee and Lynn got to talking about fish. Between them, they covered the possible effects of global climate change on lake trout in Canadian lakes; invasive Asian carp in the Midwest; the reintroduction of sturgeon into the Chesapeake River; which species of fish were native in Eastern Massachusetts rivers; etc. Since the Assabet River is visible from Dad’s living room window, of course we talked about the SuAsCo (Sudbury/Assabet/Concord) river system. I tried to participate in the conversation, but it was far more interesting to listen to the two of them. At one point, I looked at Steve and said, “Isn’t it interesting to listen to two fish experts talk?” He agreed. It’s always interesting to hear people talk about something they know well.
