Fish offal‐peat compost was hydrolysed and the resultant liquid extracts used as substrate in the cultivation of the yeast Candida utilis. The yeast was able to grow in this culture medium, attaining a growth yield of approximately 260 g biomass kg −1 total carbohydrate consumed. The biomass produced had a good amino acid composition, with a protein content of 520 g kg −1 , and a relatively low lipid content. Dry yeast was used as a feed component in the diet of cultivated rainbow trout (Oncorhynchus mykiss) in which it substituted well for other, traditional sources of protein.
