Abstract
Summary
A practical meatless ration for trout containing 55% plant material is described which is essentially equivalent to a standard liver, canned carp diet so far as growth and hemoglobin levels are concerned.
The effect of various substitutes in the ration is described.
Although this ration contains 45% carbohydrate, liver enlargement was not noted except when sprouted soybeans or poor quality yeast were included. Large scale field trials indicated that Ration C was superior to pork spleen, and equivalent to pork spleen supplemented with canned carp, as a diet for yearling brook trout on the basis of both growth and mortality.
