Cruise Report 65-S5, Rockfish 
Prepared by J. B. Phillips 
Vessel: N. B. Scofield 
Dates: Departed from San Pedro August 30, 1965; returned September 16. 
Locality: Southern California islands and offshore banks. 
Purpose: 1) To obtain, for taxonomic studies, species of rockfishes 
(family Scorpaenidae) found in southern California waters. 
2) To save eye lenses from certain species for a comparison of 
their proteins as a possible means of separating non-inter-
breeding populations. 
Results: 1) Hook-and-1ine fishing was conducted in depths from 10 to 
275 fathoms, but mostly shallower than 150 because of faulty 
wire on the deep-sea reels. Most widespread of the 33 
species taken was the vermilion rockfish, Sebastodes 
miniatus; it was taken in all general areas fished. Nearly 
as common were the green-spotted, ~. ch10rostictus and pink 
rockfish, ~. ~, followed by rosy, ~. rosaceus; starry, 
~. conste11atus; bocaccio, ~. paucispinis; chi1ipepper, 
~. goodei; and speckled rockfish, ~. ova1is. The largest 
rockfish was a 22-pound cow, ~. levis, a species that 
appears to favor bank habitats rather than areas adjacent 
to land masses. 
A number of rockfish were frozen for taxonomic studies. 
Examination of freshly caught specimens indicates that 
~. rufus, previously considered a synonym of ~. ova1is, is 
a separate species. 
Other than rockfish, the most commonly caught fish was the 
Pacific sanddab, Citharichthys sordidus. Ocean whitefish, 
Cau101ati1us princeps, and sheephead, Pime10metopon pulchrum, 
;

were common also. Blue sharks, Prionace glauca, were a 
nuisance in some areas.  
oSurface seawater temperatures varied from 61 to 69 F., but 
o65 F. water was the usual thing. 
2) Eye lenses were taken from a number of rockfish species and 
frozen for appraisal by personnel at California State
