Japanese dace Tribolodon hakonensis rearing experiments were conducted to estimate parameters related to 137 Cs uptake and excretion processes. Fish (initial mean total length 256 mm, 136 g) were reared at 20 °C for 182 days using the same daily ingestion rate (1% of body weight for 6 days per week)...
