“…Young‐of‐the‐year (YOY) rockfish samples were collected by NOAA personnel during juvenile salmonid survey cruises in the GOA from 1998 to 2003 and in the Bering Sea in 2002 (Kondzela et al ., ). Often, multiple hauls were made along a transect near a particular geographic location; some locations were sampled in multiple years (Fig.…”

Little is known about the population structure of Alaskan rockfishes, including Pacific ocean perch (POP, Sebastes alutus), and how persistent and variable oceanographic features may influence their structures. Moreover, early life history information is sparse for many species. We used data from 14 microsatellite loci to characterize the genetic structure of young‐of‐the‐year Pacific ocean perch collected during 1998–2003 from the Gulf of Alaska and Bering Sea. Broad‐scale geographic variation in genetic structure of the young‐of‐the‐year (FST = 0.005, P < 10−4) had similarities to that observed in a previous adult study. The overall correlation between genetic and geographic distance (isolation by distance) was nearly identical to that observed in the adults. Fine‐scale geographic divergence was also observed and may be the result of oceanographic circulation features within the Gulf of Alaska. Interannual variation (between cohorts) at locations sampled in more than one year is consistent with variable oceanography and fine‐scale population structure rather than the influence of a sweepstakes effect. The similarities of the young‐of‐the‐year with the adults and the pattern of genetic divergence confirm that dispersal of Pacific ocean perch is limited in all life stages.

“…Larval rockfishes are a large component of ichthyoplankton collections taken during California Cooperative Fisheries Investigations surveys and are probably important components of Alaska's marine food web, but there have been few directed studies of larval and juvenile rockfishes in Alaskan waters. In addition to harsh conditions, which discourage sampling during some seasons, few larval Alaskan rockfishes ) can be identified from morphological characteristics; and some juvenile species are difficult or impossible to distinguish visually Kondzela et al 2007). Moreover, visual identification of adults and juveniles of some species often requires the skills of experienced biologists ).…”

“…Genetic analyses have been used successfully to identify many rockfish species Kendall et al 2007;Kondzela et al 2007;Pearse et al 2007) and to develop a mitochondrial key (Li et al 2005). Because identification is based on DNA sequence differences, identification can be made on individuals of any life stage (e.g., Gray et al 2006;Kondzela et al 2007). Identification of a small number of individuals with the mitochondrial key requires only a few endonuclease digests, which is a reasonable task.…”

Diagnostic Single‐Nucleotide Polymorphisms Identify Pacific Ocean Perch and Delineate Blackspotted and Rougheye Rockfish

Diagnostic single‐nucleotide polymorphisms (SNPs) that delineate Pacific ocean perch Sebastes alutus from other rockfish species and distinguish rougheye rockfish S. aleutianus and blackspotted rockfish S. melanostictus were developed from restriction endonuclease site differences in mitochondrial DNA sequences. The SNP developed for Pacific ocean perch was specific to that species in a panel of adult rockfishes common in Alaskan waters and positively recognized all of 994 adult specimens for reactions in which polymerase chain reaction product was obtained. Species‐specific microsatellite alleles (Sma6) and SNPs were concordant in 113 blackspotted and 26 rougheye rockfish. Five additional individuals were heterozygous for the microsatellite alleles and are presumably hybrids. These SNP markers, which are substantially faster to assay and much less labor‐intensive than restriction site analyses, can be used to identify individuals of any life stage during abundance surveys and provide necessary species identification in ecological and life history studies.
