Effects of lake fertilization by volcanic activity on abundance of salmon
Eicher GJ and Rounsefell GA. 1957. Effects of lake fertilization by volcanic activity on abundance of salmon. Limnology and Oceanography. 2(2):70-76
Evidence from various sources-tree growth during the past century, chemical composition of waters of various lakes, plakton volumes, size of young salmon migrating seaward-tends to indicate that the fertilization of lake water in western Alaska by volcanic ash during sporadic eruptions may be an important factor in determining the abundance of sockeye salmon.
