Two Hæmoglobins in Chum Salmon [PDF]
Nature, 1959 OCCURRENCE of multiple haemoglobins has been reported recently in fish as well as in other vertebrates. In particular, Salmonidae was found electrophoretically to contain fairly close amounts of two or more components1,2. Some physico-chemical properties of the two components of blood haemoglobin in the salmon Oncorhynchus keta, which were prepared ...

Tryptophan requirement of chum salmon fry.
NIPPON SUISAN GAKKAISHI, 1985 Quantitative tryptophan requirement of chum salmon Oncorhynchus keta fry was determined by feeding purified diets containing crystalline L-amino acids and 5% casein as nitrogen sources for 4 weeks. The basal diet was isonitrogenously supplemented with graded levels (0.05, 0.08, 0. 16, 0.24, 0.32, 0.40, 0.48 and 0.56% in diet) of tryptophan by adjusting
