Abstract

In 2013, the Lake Superior fish community was sampled with daytime bottom trawls at 79 nearshore and 35 offshore locations. In the nearshore zone, a total of 23,432 individuals of 27 species or morphotypes were collected. Nearshore lakewide mean biomass was 5.5 kg ha-1, which was slightly higher than that observed in the past few years, but below the long-term average of 8.8 kg ha-1. In the offshore zone, a total 20,371 individuals of 13 species were collected lakewide. Offshore lakewide mean biomass was 8.9 kg ha-1, which was similar to that observed in previous years.
