Developing trout eggs and growing young fishes at various stages have been analyzed in respect of amino acid composition of their total proteins (Table 1). The results obtained are as follows: 1) Regarding the amino acid composition of unfertilized egg protein, there is little difference between the rainbow trout and the brook trout. 2) The development of rainbow trout egg shows little change in the amino acid composition of the total protein. 3) In the period from hatching out of the egg to the first feeding of the fry, body protein undergoes some variation in amino acid composition, among which decrease of alanine and increase of glycine are most remarkable. 4) The amino acid composition of body-protein of fingerlings, however, does not exhibit any appreciable variation during their growth, except as to glycine content. 5) On the basis of the amino acid composition of body-protein found for growing fingerling, a brief discussion has been made regarding the most suitable amino acid composition of the dietprotein for fingerling of rainbow trout.
