are being observed by weirs, by marking and recapture, visual observations 

 and catch data and related to environmental seasonal changes in specific 

 waters . 



Helm Bay near Ketchikan, Cottonwood Creek Systenn near Anchorage, 

 Goodpaster River near Fairbanks; began July 1953, to close March 1957; 

 $23,000; Roger W. Allin, Robert T. Baade, and George W. Warner, Leaders; 

 reports available. 



Address inquiries to: Clarence J. Rhode, as in No. 1 above. 



3. Lake Survey of Lake Louise and Associated Waters 



The objectives of this project are to determine morphological features of 

 the area, chemical and physical characteristics of the water, the flora and 

 fauna factors influencing the biota, the size and age composition of the fishery 

 and the success of previous three years of rainbow stocking in these waters. 

 The area involved in the study is a major recreational fishing and hunting area 

 and presently supports a heavy fishery for lake trout and some grayling. 

 Stocking of these waters with rainbow trout was begun in 195 3 and continued 

 through 1955 with both eyed egg and fry being used in the stocking. 



Near the Glen Allen Highway; began July 1956, closed September 1956; 

 $1,000; Roger W. Allin, Leader; reports available. 



Address inquiries to: Clarence J. Rhode, as in No. 1 above. 



4. Experimental Pond Fertilization 



The objective of this project is to determine whether it is feasible and 

 economical to increase the survival and growth of trout in ponds adjacent to 

 Juneau. Two small ponds of 3 and 5 acres have been utilized for the experi- 

 ment. Rotary screens have been installed in the outlets of the ponds and 

 both rotenoned to remove all fish. One pond is being treated with chemical 

 fertilizer while the other was left in the natural state as a control. Both have 

 been stocked and growth and survival of planted rainbow fry will be used to 

 assess value of fertilizer. 



Juneau; began July 1955, to close June 1957; $2,200; Robert T. Baade, 

 Leader; reports available. 



Address inquiries to: Clarence J. Rhode, as in No. 1 above. 



5. Catch Distribution, Composition and Size Structure of the Sport Fishery of 

 the Anchorage and Fairbanks Areas 



The objective of this project is to establish species catch distributions, 

 measure size distribution and age composition, the relative catch by time, 

 and to measure the effectiveness of experimental regulations in designated 

 waters including 12-inch minimum size and seasonal closures for the Fair- 

 banks district to determine best management regulations for the maintenance 

 of optimum stock and fishing. The usefulness of present experimental regu- 

 lations is to be determined. Other creel studies along the Glen Highway and 

 Gulkana area are to evaluate present fishing in the area in relationship to 

 the Interior Highway system and the greater Anchorage population of fishermen. 



Along the Richardson and Glen Allen Highways; began April 1953, closed 

 December 1956; $5,400; Roger W. Allin and George W. Warner, Leader; 

 reports available. 



Address inquiries to: Clarence J. Rhode, as in No. 1 above. 



6. Stocking of Game Fish in Alaska Waters. 



The objective of this project is to establish or re-establish fisheries in 

 barren waters, depleted waters or waters with unfavorable fish balances. 

 Stocking of barren and depleted waters is preceded by standard lake and stream 

 surveys for suitable waters.
