Landscape Position Project at North Temperate Lakes LTER: Fish 1998 - 1999

As part of the Landscape Position Project, we conducted fish sampling on each of 26
lakes using a variety of gear types. Sampling was conducted beginning in the 3rd week in
June and running through the endof July in 1998. In 1999, sampling was conducted from early
July through August. We used vertical gillnets of various mesh sizes (19, 32, 51, 64, 89-mm
stretch mesh) to sample pelagic fishes. The nets were fished in the deep basin of each lake
for one diel cycle. We used fyke nets to sample fishes in the shallow near shore areas.
Three nets were set, one each at differing locations defined by substrate type (muck, sand
and cobble) for one diel cycle. Three crayfish traps were set along side each of the fyke
nets. We performed electrofishing over two, 30 minute transects along the near shore area
between 0.3 and 1.5-m in depth. Our goal was to capture, identify and measure as many game
and non-game fish species as possible Sampling Frequency: one survey on each lake in late
June through August of 1998 or 1999 Number of sites: 26
