6. The Competition of Paniish With Bass in a Vilas County Lake. 



It is the object of this experiment to thin the conipeting panfish and measure 

 the change in production of the lake for bass, also the rate of growth of the bass, 

 under these less competitive conditions. 



Vilas County; began 1952, to close 1956; $3,500; Arthur D. Hasler, R. A. 

 Parker, Leaders.

7. Selective Breeding of Trout and Studies of Behavior and Adaptation to Stress. 



This study was started to determine the influence of heredity on rate of 

 growth and to study the behavior and adaptation of the various progeny lots to 

 physiological stress. 



The procedure for this part of the study is identical with the procedure em- 

 ployed for the past 2 years except the density of fish in the containers is being 

 held constant at a level fairly close to the optimum. This will allow the genetic 

 make-up of the offspring to express its influence in their rate of growth. By 

 use of a plan of statistical analysis similar to one used previously the investi- 

 gators will be able to evaluate the heritability of growth rate.

8. Competition of Trout and Bass Stocked in the Sanne Waters in Which All Other 

 Species Have Been Removed. 



The project objective is to determine the practicability of stocking bass 

 simultaneously with trout in small lakes, where deep water is available for 

 trout and shallow water for bass.

1. The Effect of Pulp and Paper Mill Wastes on Streanns as Fish Habitats. 



Objective of the project is an overall study of pulp and paper mill wastes 

 on receiving waters, either fresh water streams or tidal estuaries. Particu- 

 lar emphasis is placed on possible toxic properties, oxygen depleting character- 

 istics and on inert solids.

Chemical, Physical, and Biological Studies of the Effect of Spent Sulphite Liquor 

 on Receiving Streams. 



The objective of the project is to develop more information on the exact re- 

 lationships and conditions developing as a result of the controlled disposal of spent 

 sulphite liquor in receiving waters and the aquatic biota thereof.

 by disposal of S. S. L. in the States of Wisconsin and Michigan; began February 1, 

 1954. to close December 31, 1954; $25,000; Averill J. Wiley and Willis Van Horn, 

 Leaders.
