Survival rates of the Takifugu species after a direct transfer from seawater (SW) to freshwater (FW) or brackish water (BW). Fourteen-percent SW was used as BW. Numbers of fishes used for the analyses were: T. obscurus, n = 18 for FW; T. niphobles, n = 35 for FW and n = 36 for BW; T. pardalis, n = 10 for FW and n = 6 for BW; T. poecilonotus, n = 32 for FW and n = 10 for BW; T. rubripes, n = 26 for FW and n = 11 for BW; and T. porphyreus, n = 6 for FW.
