Fertilization of an Oligotrophic Lake with a Deep Chlorophyll Maximun: Predicting the Effect on Primary Productivity
Journal of Fisheries and Aquatic Sciences
(1997)
Abstract
We investigated how epilimnetic fertilization would affect chlorophyll levels and light penetration of oligotrophic sockeye salmon (Oncorhynchus nerka) lakes and how the resulting self-shading would affect primary production of the prominent deep chlorophyll maxima (DCM) of the lakes. Epilimnetic nutrient additions to large mesocosms (330 m3) in Redfish Lake, Idaho, increased levels of primary productivity and chlorophyll a but decreased Secchi depths and light available in the metalimnion and hypolimnion...
