Great Lakes Environmental Assessment and Mapping Project


Fishing in the Great Lakes has a long, intricate, and at times, tumultuous history. From the earliest records of fishing by native peoples, to the growth and collapse of the commercial fishing industry in the mid-1900s, and into current times where recreational fishing is growing in importance while commercial fishing is diminishing, we see the influence of humans on the resource along with some consequences to the entire Great Lakes ecosystem. As efforts to manage fisheries are further complicated by many accidental and purposeful species introductions, our characterization of stressors related to fisheries represents an important albeit coarse approximation of probable impacts on the Great Lakes.


The GLEAM project assesses five stressors related to fisheries in the Great Lakes.
