Stage-specific vertical distribution of Alaska plaice (Pleuronectes quadrituberculatus) eggs in the eastern Bering Sea
The stage-specific distribution of Alaska plaice (Pleuronectes quadrituberculatus) eggs in the southeasternBering Sea was examined with collections made in mid-May in2002, 2003, 2005, and 2006. Eggs in the early stages of development were found primarily offshore of the 40-misobath. Eggs in the midd...
