The effect of ... -
The Absorption and Metabolism of Arsenic in Fish
(Fiskeridirektoratets skrifter / Serie Teknologiske undersøkelser;Vol. 5, No. 12, Research report, 1972)The absorption and metabolism of inorganic arsenic in rainbow trout (Salmo gairdneri) has been investigated by means of radioactive tracers. The results obtained show that the fish will absorb inorganic arsenic when this ... -
The amino acid composition and the protein value of four selected fish meals for the young chick
(Fiskeridirektoratets skrifter / Serie Teknologiske undersøkelser;Vol. 5, No. 5, Research report, 1968)A winter herring meal, a North Sea herring meal, a scad meal and a mackerel meal were tested as supplements to a basal vegetable chick diet and were analyzed for amino acids, vitamins and the common chemical constituents. ... -
