Fish Waste for Profit — Not Pollution GEORGE M. PIGOTT, Associate Professor Institute for Food Science and Technology University of Washington Seattle, Washington INTRODUCTION Food—starvation-waste—pollution-land and water! Utter one of these words today and you implicate them all. Summed up they spell "Man's survival on earth". For many years the scientific community has been predicting a major disaster in the world due to shortage of proper foods. However, the producing areas of the world were so busy with their own problems, that of taking from the earth, that the cries went unheeded. A primary product needed in solving the human food shortage is protein, more particularly animal protein. Some two-thirds of the world's population is deficient in this material and there is little hope that agriculture alone can supply the needs and time to prevent major disaster. The world is looking to the marine resources for help in the solution of this animal protein deficiency, since the oceans represent a large, untapped source of high-quality of animal protein. It is interesting to note (Figure 1) that the world is feeding an increasing amount of marine food to animals (a much more inefficient utilization of protein for humans) at the expense of decreasing the relative amount fed to humans. Whereas in 1958, we used approximately one-sixth of the world's fish catch for animals, today we use about one-third for this purpose. The situation in the United States is even more unbalanced (Figure 2) in that well over fifty percent of the fishery products consumed is by animals. Furthermore, as shown in Figure 2, we are importing approximately the same amount of fish for non-human use as we are producing in the total United States catch. This trend cannot continue! The source of fish meal that comes from other countries will decrease as these countries raise their standards of living, both through raising food animals and utilizing what is now "fish meal for animals" in forms that are acceptable to humans. There are large untapped sources of protein from the sea that must be exploited in the future. On the other hand, the waste from plants presently processing edible fish represents another source of raw material. At the present time up to 50 percent of all edible fish taken from the sea is discarded as waste. This ranges from some 35 percent waste for salmon to as high as 80 percent for shellfish. This loss of a much needed food product is contributing to the pollution in our inland waters, both in suspended and dissolved solids. So we technologists and engineers in the food industry, and more specifically in today's discussion, the seafood industry, have our work cut out for us—utilize waste and thereby do our part in feeding mankind and minimizing pollution from waste disposal. 660
