1. Fertilization of Low Nutrient Lakes. 



The role of alkalization in reducing brown color of bog lakes has been studied. Bog 

 lake soils are analyzed to determine availability of nutrients. Isotopes are used 

 in laboratory phases of the study. 



Northern Wisconsin and Univ. of Wisconsin, Madison; planned for 3 years; $4,000;

2. Production of Fish in Northern Wisconsin Bog Lakes. 



The project is designed to study production, standing crop, carrying capacity and 

 mortality of trout in a mono-species community, and of bass in competition with 

 pan fish. The lakes are of the bog type. 



Chippewa County and Vilas Counties; continuing for 5 years; $7,000; A. D. Hasler,

3. Olfactory Sense of Fishes and Its Relation to Homing. 



The study is of the basic type involving the physiology of the sense of smell in 



fishes. Field studies on sensory abilities of migrating salmon have been carried 

 out.

1. The Effect of Pulp and Paper Mill Wastes on Aquatic Environments. 



The project is organized to determine the total effect of these wastes on the habitat, 

 behavior, propagation, and survival of game and forage fish. 



Work is done at Appleton, and on other rivers where pulp mills have been built; 



began July 1, 1942, continuing; some reports available.
