Atlantic salmon Salmo salar were given three dietary doses of vitamin D 3 for a period of 11 weeks: diet groups I, II and III received a 0.04, 2.21 and 28.68 μg g −1 diet of vitamin D 3 , respectively. The tissue distribution of vitamin D 3 was investigated, and between diet groups II and III, the level of vitamin D 3 found in the tissues was increased by a factor similar to the increased level in the feed. No effects were observed on weight gain, survival, plasma level of calcium, red blood cell count or haematocrit, relative to the dietary levels of vitamin D 3 . The results showed that while the plasma concentration of 25(OH)D 3 increased between diet groups II and III, the concentration of 1,25(OH) 2 D 3 decreased.
