For each species or ecosystem that we study, we attempt to understand what factors affect species growth and survival and cause or contribute to population fluctuations over various time periods (e.g., between years and between decades).
Our scientists at NOAA Fisheries Alaska, are involved in an array of ongoing field studies and surveys, to help us better understand and document the current state of marine life and their habitats within the Alaskan region.
Alaska has an abundance of marine life including whales, dolphins, seals and fish. In fact, the walleye pollock resource supports the largest fishery in the U.S. Why is this? Availability of prey has a lot to do with it.
