1. Linnnological Investigation of Lake Lynn. 



Objectives of the project are to nnake studies of temperature, dissolved 

 oxygen, pH, alkalinity, sulfate, iron, etc. at regular intervals for one year 

 at selected stations, with the hope of deternnining possible biological produc- 

 tivity and of establishing what steps may be required to increase the abundance 

 of fish and other aquatic organisms. 



Isaak Walton League, Morgantown Chapter, cooperating; Monongalia County; 

 began September 1953, to close August 1954; $2,000; Leland H. Taylor, Leader. 



Address inquiries to: Earl L. Core, Head, Department of Biology, West 

 Virginia University, Morgantown, W. Va.

1. Etiology of Fish Diseases. 



A study to determine which of the diseases are caused by pathogens and which 

 have nutritional origin. Isolation and determination of the eventual pathogens is 

 involved, and development of control measures. 



Hdqrs. Leetown; began 1947, continuing; S. F. Snieszko, Leader. 



Address inquiries to: S. F. Snieszko, Director, Microbiological Laboratory,

2. A Study of the Toxicity of Various Chemical Compounds, Insecticides and Herbi- 

 cides, on Warm- and Cold-Water Freshwater Fishes. 



Objectives of the project are to screen the chemicals toxic to fish and to 

 determine the mechanism of action of the most toxic substances, and make prac- 

 tical application of the results. 



Hdqrs. Microbiological Laboratory, Kearneysville; began April 1952, to 

 close June 1954; E. H. Hollis, Jr. , and Robert E. Lennon, Leaders. 



Address inquiries to: S. F. Snieszko, as in Np. 1 above.

1. Fish Ecology Studies, With Special Reference to Muskellunge and Panfish. 



Muskellunge studies include determination of feeding habits of early stages 

 of fry, factors influencing their survival in rearing ponds, and the practicality 

 of artificial feeding; the suitability of marking by finclipping or tagging for future 

 identification; survival of muskellunge of different sizes planted in natural lakes; 

 and the effects of planted muskellunge on stunted panfish populations. 



Panfish studies include the determination of population density, growth rates 

 and condition of a stunted panfish population; and the effects of introduction of 

 plantings of nnuskellunge fingerlings of different sizes on panfish populations. 



Rearing ponds at Spooner and nearby lakes; began 1953, to close 1958; 

 $10, 000; Leon D. Johnson, Donald K. Dunham, Stanley Kmiotek, Leaders. 



Address inquiries to: Conservation Department, Area I headquarters, 

 Spooner, Wis. 



2. Evaluation of Lake Trout Stocking in Lake Superior. 



Eggs of lake trout are taken from adult spawners in Lake Superior. These 

 are hatched and reared to fingerling and yearling sizes. Various lots are being 

 finclipped and planted in Lake Superior to evaluate returns from plantings of this 

 type.
