Ontogenetic Variation in the Multiple Hemoglobins of Arctic Charr, Salvelinus alpinus
Changes during development in the multiple hemoglobins of hatchery-reared Arctic charr, Salvelinus alpinus, that originated from an anadromous stock from Nauyuk Lake, Northwest Territories were examined by starch gel electrophoresis. A total of 10 anodic and 7 cathodic hemoglobins were expressed dur...
