Kiyi here on their annual fish sampling tour of Lake Superior.

The research vessel Kiyi, based in Ashland and operated by the U.S. Geological Survey, arrived Duluth today (above). They are on their annual offshore fish community survey of Lake Superior to sample the fish population at 55 stations around the Lake (see map below). Mark Vinson (right) is Station Chief at the Lake Superior Biological Station in Ashland, a part of the U.S. Geological Survey and told me they use a bottom trawl to collect and analyze the fish at each of the stations. They note age, length, weight, sex and maturity of each specimen and look for contents in the stomach, which provides information about eating habits, including who is eating who in the food chain. This information is shared with a wide variety of government entities in the 3 states that border Lake Superior, and Canada. One use provides important information that is used to set limits for commercial and recreational fishing. Just before arriving Duluth they stopped at their station at the mouth of the Lester River. They will depart Duluth at 7 am on Wednesday morning.
