Effect Of Water Hyacinths And Fertilization On Fish-Food Organisms And Production Of Bluegill And Redear Sunfish In Experimental Ponds

Eighteen O.l-acre ponds at the Auburn University Fisheries Research Unit, Auburn, Alabama, were used from April 5 through November 20, 1967. Both species of fishes were stocked together randomly at a rate of 4,000 fingerlings per acre. The experimental design consisted of three control ponds without fertilization or hyacinths; three control ponds without fertilization, but with hyacincths; three ponds with 0-8-0 (N,P,K) fertilization, but no hyacinths; three ponds with 0-8-0 fertilization, but with hyacinths; three ponds with 8-8-0 fertilization, but no hyacinths; and three ponds with 8-8-...
