Blood volume in the hemoglobinless Antarctic teleost Chionodraco hamatus (Lönnberg)

Abstract Blood volume in the hemoglobinless Antarctic icefish Chionodraco hamatus (Channichthyidae) has been determined by the Evans blue dye dilution technique. A mean blood volume of 127.0 ± 5.0 ml kg −1 body weight was found, a value even higher than that previously found in another icefish, Chae...

Description
Summary:Abstract Blood volume in the hemoglobinless Antarctic icefish Chionodraco hamatus (Channichthyidae) has been determined by the Evans blue dye dilution technique. A mean blood volume of 127.0 ± 5.0 ml kg −1 body weight was found, a value even higher than that previously found in another icefish, Chaenocephalus aceratus (mean blood volume, 89.7 ml kg −1 body weight; Hemmingsen and Douglas [1970] Comp. Biochem. Physiol., 33 :733–744; Twelves [1972] Br. Antarct. Surv. Bull. 37 :85–92). This extraordinary hypervolemia appears unique among teleosts and may compensate for the absence of hemoglobin in the icefish. © 1995 Wiley‐Liss, Inc.
