HARRY, JR. AND WALTER G. JONES, THROUGH THE COURTESY OF ALFRED R, MORGAN, FISH COMMISSION OF OREGON. c'^.S "'£\\^—( Ilk FIG. 2 - DOCK FOR UNLOADING WHOLE FISH. Not all fish waste can be used for feeding mink. The waste must be strictly fresh, just as with fish used for human food. It must be relatively free of thiaminase, as otherwise the mink may get Chastex paraly- sis. And it must not be too oily, since a high content of oil is said to cause yellow-fat dis- ease, especially if the oil is highly xinsaturated. The manufacture of waste into mink feed varies somewhat from one locality to another. In the cities of Astoria and Newport, Ore., the process is essentially one of grinding the waste, placing it in paper bags, freezing the bags with the waste, and holding them in frozen storage until needed. H whole fish are used, the process is the same except that the fish are washed thoroughly before they are ground. The photo- graphs show the various steps in the FIG. 3 - UNLOADING FISH FROM DRAGGER. ON THIS PAR- TICULAR TRIP ONLY 20 000 POUNDS OF FISH WERE CAUGHT OWING TO ROUGH WEATHER. THIS VESSEL HAS A 17-FOOT BEAM AND A LENGTH OF 58-FEET. BEING A COMBINATION BOAT, IT CAN BE USED FOR DRAGGING, TROLLING (fOR BOTH SALMON AND TUNa), AND FOR HALIBUT FISHING. NOTE THE DECK HOSE USED FOR CLEANING THE PEN BOARDS. ABSOLUTE CLEANLINESS IS ESSENTIAL TO THE DELIVERY OF QUALITY Pl
