1. Inventory and Classification of Water Areas With Reference to Water Quality 

 and Fish Productivity. 



The project objectives are to survey and classify all lakes, ponds, and 

 streams in the State. A streanri classification has been devised and streams 

 are classified accordingly. Lake and inripoundment surveys include nnapping 

 and general lake survey. 



Game and Inland Fish Connmission cooperating; statewide; began 1949, 

 continuing; R. D. Van Deusen, Leader.

2. A Study of the Distribution and Relative Abundance of Fish Species in Maryland. 



Objectives of the project are to determine the distribution of the various 

 fish species in the State and gather information concerning their relative abun- 

 dance. Data are obtained from seining, trapping, drugging and creel census 

 projects. Distribution records now numerous enough for publication and report 

 are being prepared. 



Statewide; began 1948, indefinite; Romeo Mansueti, Leader.

3. Study of the Harvest of Sports Fishes from Various Bodies of Water in Maryland. 



Creel census studies are designed to determine total harvest of fish in several 

 Maryland waters. These studies include analysis of species taken, estimated 

 weights, habits of fishermen, etc. 



Selected waters; began 1951, indefinite; Harold J. Elser, Leader; reports 

 available.

 forecast the times at which fish bite best. Data fronn 1, 538 fishing trips on Loch 

 Raven, Maryland, were used for the study. 



Began January 1953, to close September 1953; Harold J. Elser, Leader; re- 

 ports available. 



Address inquiries to: Harold J. Elser, as in No. 2 above. 



5. Determination of the Average Growth Rates of Maryland Fish Species. 



Scales from fish collected by various methods are analyzed for length at 

 each annulus. Results are to be combined into average growth rates for each 

 species for each of the three geographic provinces of Maryland. 



Began 1948, indefinite; Harold J. Elser, Leader. 



Address inquiries to: Harold J. Elser, as in No. 2 above. 



6. The Economic Value of Sport Fishing in Tidewater Maryland.
