11. Lake Distribution of Largemouth Bass 



The objectives are to learn the facts and factors of lacustrine distribution 

 and movementb of largemouth bass by netting, angling, tower observation, 

 and SCUBA. 



Began July 1955, to close July 1957; R. Jack Schultz, Leader. 



Address inquiries to: R. J. Schultz, Department of Fisheries, Natural

 man, Leader. 



Address inquiries to: Karl F. Lagler, as in No. 1 above. 



13. Food Habits of the Leucichthys spp. and its Relation to the Ecology of Lake 

 Michigan 



Analysis of the food habits data of the Leucichthys may enable us to define 

 its position as an existing population in relation to the other animal populations 

 in that particular ecological unit. It may partly or wholly influence fluctuations 

 among the other organisms or some of their peculiar behavioural character- 

 istics. 



Other objectives are to determine the bathymetric distribution of the chub 

 in relation to the vertical distribution of Mysis and Pontoporeia as well as 

 population levels and rates of growth of the fish under investigation. 



The project provides a basis for determination of the degree of predation 

 and competition in that particular ecological community and may be used as 

 important bases for resource management of the chub, the most important 

 commercial fish in Lake Michigan.

15. Effects of Sub-lethal Levels of Pollution on the Fish and Fish-food Organisms 

 of Warm-water Streains 



This project is an evaluation of effects of domestic and industrial pollu- 

 tion on biota of the stream. Conditions range from polysaprobic to oligo- 

 saprobic and effects on aquatic organisms of varying types and intensities of 

 pollutants are being evaluated.
