Abstract: | Rainbow trout, Oncorhynchus mykiss (Walbaum) were rendered acutely anaemic by immersion in phenylhydrazine HC1 at 5° C. Following splenectomy or sham operation erythropoiesis was induced by gradual warming. No consistent or significant differences in red cell numbers, haemoglobin, haematocrit, mean erythrocytic volume or haemoglobin or haemoglobin isomorph system organization were evident during or following recovery. It is unlikely, therefore, that reported acclimatory adjustments in haemoglobin isomorph abundances can be attributed to site-related differences in erythroid cell lineages. |
