20. Experimental Hybridization of Brook and Mackinaw Trout (36-FR-l). 



The objectives of this project are: To cross the two species (male mackinaw x female 

 brook and female mackinaw x male brook); to propagate the hybrids for taxonomic 

 studies; to experimentally breed the hybrids by artificial reproduction; to stock 

 them in a virgin lake to study their survival and practical management values; 

 and to determine their value as compared to the mackinaw trout.

1 Vital Statistics of the Yellowstone Lake Fishery (Proj, 27). 



The objective is to determine the numbers of fish and the sizes of fish to be expected 

 at Yellowstone Lake at different levels of fishing pressure and hatchery activity.

 1. Ward Cove Survey. 



The objective was a chemical, biological, and hydrological survey of Ward Cove and 

 adjacent Tongass Narrows waters to determine water characteristics before dis- 

 charge of wastes to these waters from operation of the Ketchikan Puip Mill now 

 being constructed at Ward Cove. This survey is to form a basis for evaluating 

 future effects of Magnesia - base siolfite pulp wastes on fish and othermarine life 

 in adjacent receiving waters. The project included the collection of samples at 

 various depths at 9 selected sampling stations at various tide levels throughout 

 the year. Observations were made of the effects on adjacent waters of pollution 

 from tht fish reduction plant which operated at Ward Cove during the month of 

 August 1952. 



Ward Cove and adjacent coastal waters of Tongass Narrows approximately 5 miles 

 northwest of Ketchikan; began October 1951, planned for 1 year; $15,000; William L. 

 Porter, Project Leader; limited suiply of project reports available about Sept. 1953.
