(Sebastes spp.) that had their DNA sequenced for comparison to DNA from the lar- 
val rockfish collected as part of this study in 2017 in the Gulf of Alaska. GenBank 
accession numbers for an additional 11 larvae were OM141006—OM141016.

Plumarella superba were sequenced by using the same 
methods described in a previous paragraph. Species iden- 
tification was performed by comparing the resulting 
sequences to sequences from this study (Table 1) or to 
sequences found in GenBank by using the Basic Local 
Alignment Search Tool (BLAST, available from website) 
(Johnson et al., 2008) if an exact match did not exist 
among sequences provided in Table 1.

Results and discussion 
A sample collected with the plankton pump on 8 June 
2017 in the Gulf of Alaska south of Unimak Island, Alaska 
(54°10/N, 162°14’W), at a depth of 93 m in coral habitat 
included a single larval rockfish (Fig. 1). No larvae were 
captured in samples taken during the other 7 deployments 
of the plankton pump. The habitat where the larval rockfish

Images of deepwater coral habitat and rockfish larvae (Sebastes spp.) associated with collections made with a plankton pump 
during this study or made during the bottom-trawl survey conducted by the NOAA Alaska Fisheries Science Center (AFSC) 
in the Gulf of Alaska in 2017: (A) deepwater coral habitat where the larval northern rockfish was collected with the plankton 
pump, (B) the northern rockfish larva collected in the plankton pump, (C) a larval rockfish with a coral of Plumarella superba 
from the collection of specimens captured during the AFSC bottom-traw] survey, (D) rockfish larvae collected from corals sam- 
pled during the AFSC bottom-traw] survey, (E) a larval rockfish nestled in a coral of Callogorgia compressa collected during the 
AFSC bottom-trawl survey, and (F) a larval rockfish retrieved from the collection of the AFSC bottom-traw] survey.
