PACIFIC OCEAN PERCH (SEBASTODES ALUTUS) pepper (S. goodei), and channel rockfish or "idiot" (Sebastolobus alascanus) were prepared and frozen in one-pound packages in commercial filleting plants, using regular commercial procedures. Samples of vermilion rock- fish (Sebastodes miniatus) and red rockfish or "red snapper" (S. ruberrimus) were prepared at the Seattle Technological Laboratory from fish caught off the coast of Washington by the Service's exploratory fishing vessel, John N. Cobb. These fish had been frozen whole aboard the vessel. At the laboratory they were thawed in cold running water and filleted. The fillets were packaged and refrozen. The exact effect of this procedure on the cold-storage keeping quality of the fillets is not known. The results of the storagetests on these samples maybe of interest, how- ever, and are included in this report. The skin was removed from the fillets of red rockfish (Sebastodes iniberrimus). vermilion rockfish (S. miniatus), and orange rockfish (S, pinniger) before packing and freezing. The fillets of the remaining species were packed with the skin on. Samples of ocean perch (At- lantic ), Sebastes marinus, fillets were obtained from Gloucester, Massachusetts, where theyhad been prepared, packaged, and frozen under regular commercial condi- tions. These fillet samples were shipped frozen (usingdry ice) via air express to Seattle, Washing- ton. The ocean perch (Atlantic), S_. marinus. catch leads that of any other fish in the New England area. Also, the general external appearance of this species resem- bles that of some of the Pacific Coast rockfish, especially the Pacific ocean perch (Sebastodes alutus). For these reasons it was included in these tests as a basis for comparison. All samples were stored at 0° F. Organoleptic observations were made on the thawed fillets and on the cooked pro
