Early life history of capelin (Mallotus villosus) in the northwest Gulf of Alaska: a historical perspective based on larval collections, October 1977-March 1979
Analyses of ichthyoplankton samples collected in the vicinity of Kodiak Island, Alaska, during the period October 1977–March 1979 provide new information on the spawning strategy and early life history of capelin in the Gulf of Alaska. Seasonal variation in abundance, length, and distribution of cap...
