Abstract
Fish production (yield) is related to mean depth and total dissolved solids for 34 north-temperate lakes. Segregation of these lakes into two groups, depending mainly on fishing intensity, refines the relationship. The "morpho-edaphic" index, an expression combining mean depth and total dissolved solids, provided a method for estimating the potential production of a lake. The usefulness of this method depends on control of area, altitude, and climate for the lakes under consideration. Anomalous environmental conditions of large magnitude could alter the relationship markedly. Most notable of these conditions are: excessive pollution, high flushing rate, extreme turbidity, extreme water-level fluctuations, extensive winter or summer kill, alternate year spawning or extensive epizootic mortality.This publication has 4 references indexed in Scilit:
