Diel Vertical Migration of Pandalus borealis in Kachemak Bay, Alaska
Catches of Pandalus borealis by surface-to-bottom pot fishing in Kachemak Bay, Alaska, showed that this species was distributed in large numbers throughout the water column at night and suggested a diel vertical migration. The shrimp apparently left the vicinity of the bottom about dusk and returned...
