Crabs are important to Glacier Bay
The Life and Times of Dungeness Crabs in Glacier Bay National Park and Preserve
Life history of Dungeness crabs; distribution of Dungeness crabs throughout Glacier Bay; animal ecology; the effectiveness of a marine preserve for protecting species, such as Dungeness crab; special adaptations to a marine environment
Dungeness crabs are an important benthic species of Glacier Bay. Glacier Bay was closed in 1999 to all commercial fishing of Dungeness crabs because of the possibility of a collapse of Alaska's Dungeness fisheries. Preliminary studies indicate that this closure will increase the size and abundance of this important species, as well as improve its genetic biodiversity.
