The kidney is glomerular with nephron that consists only of proximal and collecting tubules. The glomeruli of fish collected in February showed atrophy and did not contain blood cells. By contrast, the glomeruli of fish collected in July were well vascularized and contained some blood cells. These results may suggest seasonal changes in glomerular function with a reduced or non-functional condition of the glomeruli during winter when kidneys are physiologically similar to those of aglomerular fishes. These morphological differences in the glomeruli of E. gradlis may be related to the conservation of antifreeze glycoproteins in their sera and to the adaptation for cold water during the winter.}, pages = {71--75}, title = {ON THE KIDNEY OF THE SAFFRON COD, ELEGINUS GRACILIS, AND ITS COLD ADAPTATION (Eleventh Symposium on Polar Biology)}, volume = {3}, year = {1990} }
