Abstract
Drifting algae and seagrasses floating on the surface of Washington's marine waters form a unique and ecologically important habitat for the early life history stages of some species of Pacific rockfishes (genus Sebastes). Investigations aimed at understanding the significance of this habitat as an intermediary step toward the benthic and midwater environments favored by adult rockfish have been plagued by difficulties in accurately identifying the species of juvenile rockfish encountered during habitat sampling. The difficulty stems from the many sympatric species that share similar morphological features and overlapping meristics as larvae and juveniles. In this study, we successfully used allozyme data obtained from 37 presumptive gene loci in 11 reference species to confirm the identities of 149 juvenile splitnose rockfish (S. diploproa) and six black rockfish (S. melanops). Genotypes from 29 juveniles did not match those from any of the reference species and could not be positively identified. Future efforts employing molecular techniques for the identification of rockfish species during early life history phases would benefit from the application of recent advances in DNA methodologies such as the analysis of mtDNA or microsatellites
