THYROIDAL CONTROL OF RADIOPHOSPHORUS METABOLISM IN YEARLING SALMON, SALMO SALAR L.
In one experiment yearling Salmo salar L. treated with 0.3% thiourea for a fortnight absorbed 50.3% of P 32 from the water whereas in control they could utilize only 40.1%. The uptake in various tissues (bone, liver, kidney, and muscles) was always more in treated fishes than in control. In a second...
