Considerable information exists for the behavior and fate of tritiated water in mammals; however, few experimental data are available on the incorporation of tritium from tritiated water into fresh water fishes. Of particular interest are fish that begin and end their lives in a tritiated environment. In the present study trout and channel catfish eggs were hatched and the fish maintained in tritiated water for four months. In addition, two species of minnows native to the southwest United States were maintained in tritiated water and offspring from these fish were reared in tritaited water for five months. Some of these native fish were maintained for two months in large outdoor pools in which part of their food was grown naturally. The tritium concentrations in aquaria water were held constant during the experimental period. The results show that for these species of fish living in tritiated water the concentration factor for organic bound tritium is generally less than unity. The concentration factor is defined as the specific activity of tritium in dried body tissue divided by that in the water in which the fish were reared. Literature concerning behavior of tritium in aquatic food chains after release in nuclear industry effluents is reviewed.
