Seasonal habitat use and productivity of three commercially important Rockfish species in the Gulf of Alaska, 2012-2014
This study examined the value of bare, high relief rocky/boulder, and high relief coral habitat for three commercially important rockfish species. The density of rockfish found within these habitats was investigated as well as pelagic prey availability, diet content, reproductive productivity, and e...
