North Dakota A-15-R John Owen $8,000 



Garrison Reservoir commercial fisheries investigations - The life history of bullheads, 



goldeye, and yellow perch are being studied. Also investigated is the behavior of these 



fish in response to physical factors, such as turbidity, which are associated with reservoirs. 



North Dakota 4.-23-D Dean Hildebrand Completed 1967 



A survey of commercial fisheries on the mainstem reservoirs of the Upper Missouri River 

 System - To determine possible expansion of the commercial fisheries, the University of North 

 Dakota has investigated Fort Peck Reservoir of Montana, Garrison Reservoir of North Dakota, 

 and Oahe and Fort Randal Reservoirs of South Dakota. 



North Dakota 4.-30-R John Owens $12,000 



A study of the commercial fishery potential of Lake Ashtabula - This study is designed to 

 study the movements, growth, and population structxire of bullheads and yellow perch. Popu- 

 lation density and rate of growth before and after harvesting are investigated also. 



North Dakota A-5A-R John Owens $3,000 



Investigation of gonadatrophins in stimulating spawning and white suckers - North Dakota 

 University has underway studies of the development of techniques for using pituitrin to 

 induce spawning of white suckers. 



Ohio A-47-R William M. Tidd $16,000 



The status of whirling disease in Ohio waters - This project is designed to determine if 

 whirling disease exists in Ohio salmonids in private and public waters, if spores are present, 

 and by what methods the disease is transmitted. 



Oklahoma /t-2^.-R Robert Summerfelt $26,300 



Commercial fisheries investigations - The relation between sediment type and the distri- 

 bution and abundance of invertebrates and fishes is studied, at Lake Carl Blackwell. Sediment 

 surveys are made semiannually at five selected sites along each of 30 transects across 

 the lake. Biological and hydrographic data are also collected. In addition, the food habits 

 of commercial fishes from five reservoirs are being studied. 



Pennsylvania 3-67 -R Keen Buss $60,000 



A study to establish a program to increase the production of high value commercial fishes in 

 Lake Erie - This project involves a study of the life history of the walleye, attempts to 

 locate and propagate blue pike, and to conduct experimental coho salmon stocking program. It 

 also provides equipment for a research vessel to study these fish and their environment in 

 the Eastern Basin of Lake Erie. 



Vermont 3-59-R Jon K. Anderson $5,000 



Investigation of commercial fisheries potential of Lake Champlain - Information is obtained 

 on the number and activities of live bait supplies along the lake to determine the economic 

 value of the bait industry and seasonal demand for specific types of bait. This study is 

 also concerned with the relative distribution and abundance by species and weight of existing 

 fish populations which may be harvested commercially. 



West Virginia 3-58-R Roger Schoumacher $10,250 



Investigation of the commercial potential of fishery resources in West Virginia - This study 

 is designed to investigate the commercial potential of channel catfish and mussels along the 

 Ohio and Kanawha Rivers. The catch of nets set at selected locations along the Ohio River 

 is evaluated for size and age composition of the catfish population. The source and type of 

 pollution that affects the flavor of these fish are also being studied.
