1. Life History and Management of Brook Trout in Lawrence Creek 



A complete creel census and semi-annual population estimates are being 

 conducted on three miles of trout stream. Different angling regulations are 

 being tested during different seasons to determine optimum regulations for 

 brook trout management. The value of refuge areas and dynamics of an un- 

 fished brook trout population are being studied. 



Adams and Marquette Counties; began April 1955, indefinite; $15,000; 

 Jannes T. McFadden, Leader; reports available. 



Address inquiries to: James T. McFadden, Lawrence Creek Research 

 Station, Route #2, Westfield, Wisconsin. 



2. Rate of Exploitation of Warm Water Fishes in a Small Flowage 



The objective is to determine the use by anglers of populations of northern 

 pike, muskellunge, largemouth bass, bluegill, black crappies and other warm 

 water fishes under various angling regulations. 



A complete record of fishing statistics is maintained by use of a free per- 

 mit system of fishing during specified daily hours. Population estinnates by 

 mark and recapture methods by trap netting and based on angler caught fish 

 are accomplished for connparison with harvest figures. 



The rate of growth of fishes present is determined from data collected 

 at the checking station.

3. Evaluation of Stocking Fingerling Walleye in Escanaba Lake 



The objectives are to determine the survival rate and return to the angler 

 of walleye fingerling stocked in a lake where a walleye population is already 

 present, and their effect on the harvest and the existing population. Marked 

 walleye fingerling were stocked in 1954, and a second stocking is contemplated 

 for 1957. A complete record of the harvest is kept by a compulsory permit 

 system, and all fish taken from the lake are examined by department person- 

 nel. Year-round fishing is permitted, without size or bag limit. Annual 

 estimates of the population are made by the marking and recovery method 

 to determine rates of exploitation and mortality.
