Krieger, Kenneth (1992) Shortraker Rockfish, Sebastes borealis, Observed from a Manned Submersible. Marine Fisheries Review, 54(4), pp. 34-37.
These are the first documented observations of shortraker rockfish, Sebastes borealis, in their natural habitat. The in situ observations were made from a manned submersible in 1991 in the eastern Gulf of Alaska. Eleven dives were completed from 207 to 357 m (679-1,171 feet); shortraker rockfish were observed during four dives. Their apparent indifference to the submersible allowed observations of their spatial distribution and habitat. The shortraker rockfish observed (20 total) were not schooled and were at least 50 m (164 feet) apart. Nineteen were on the bottom, and one was 0.5 m (20 inches) above the bottom. They were using 3-12° sloping terrain composed of either silt or pebbles interspersed with boulders (diameter 0.5-4.0 m (1.6-13 feet)); six were next to boulders.
