Glacier Bay National Park and Preserve protects million acres of rugged mountains, temperate rainforest, bountiful coastline, deep fjords, open ocean, rich estuaries, wild rivers, lakes, streams and ponds, and a plethora of fish! This complex and dynamic, temperate ecosystem has nearly 1200 miles of coastline, including 950 square miles of ocean habitat and greater than 1000 freshwater systems of available fish habitat for over 200 fish species. From the smallest forage fish like Pacific herring and sandlance to deepwater giants such as 500 pound Pacific halibut and 14-foot sleeper sharks, fish play critical roles in Glacier Bay's rich ecosystems.
