The quarterly period of April, May, and June, 1951, was spent in the examination of this year's spawning sea-trout and further experimentation on the fertilizing of Copano Lake. Previous collections of trout ovaries and testes which had been preserved in Bouin's solution were embedded in paraffin, sectioned, and mounted for photographical purposes and further analysis of the trout and redfish sexual development. Some fish tagging was carried out in the field on trout of the second year class. Experimentation was begun on the analysis of age groups and year classes by the otolith method of determination.
