Bipartisan Legislation Gives Great Lakes Fishery Research A Boost

The Great Lakes Fishery Commission (GLFC) is celebrating a major victory for the Great Lakes ecosystem. The Great Lakes Fishery Research Reauthorization Act (GLFRAA) has been passed by the U.S. House and Senate, ensuring continued federal funding for the U.S. Geological Survey's (USGS) Great Lakes Science Center through 2030. This funding will support research on native and invasive fish species, habitat conditions, and biological assessments, ensuring the long-term health of the Great Lakes. The passage of GLFRAA is a testament to the power of bipartisan support for the Great Lakes. Read the press release here.

Canada's Secret War Against Invasive Carp

The Department of Fisheries and Oceans (DFO) is waging a quiet war against invasive carp in the Great Lakes, using electro probes, underwater nets, and traps to detect and remove these destructive fish. The stakes are high, with invasive carp capable of consuming up to 40% of their body weight in aquatic vegetation and insects daily, potentially altering the ecosystem forever. Invasive carp, particularly grass carp, pose a significant threat to the Great Lakes ecosystem. If established, they could outcompete native species for food and habitat, causing irreversible damage. The DFO has processed 34 grass carp pulled from Canadian waters since 2012, with 11 capable of reproduction. Wildlife biologists warn that if even one of the four invasive Asian carp species gains a foothold i
