• On 15 May 1980, the authors found a large school of juvenile Pacific sandfish (Trichodon trichodon ) near Point Howard (135 degree 3'00"W-58 degree 20'00"N). While watching, this school of nearly 5,000 juvenile Pacific sandfish remained densely-packed, adjacent to a vertical bedrock wall. In June 1980, at Funter Bay (134 degree 54'20"W-58 degree 14'00"N) and Point Dundes. (136 degree 16'50"W-58 degree 18'55"N), schools of juvenile Pacific sandfish were (fork length, 35-61 mm) mixed with pink salmon (O. gorbuscha ) (fork length, 34-68 mm). These schools were sampled with a dip net or beach seine. The stomach contents of 10 Pacific sandfish (fork length, 37-47 mm) and 10 pink salmon (fork length, 44-65 mm) were examined. Both species shared the same food supply of planktonic crustacean zooplankters such as euphausiid larvae and calanoid copepods, as well as epibenthic harpacticoid copepods and the larvaceans Oikopleura .
