2. Evaluation of Warm Water Reclamation 



The objective is to evaluate the success or failure of the warm water recla- 

 mation project, including stocking rates, sjjecies connbinations, effects of re- 

 contamination by other species, growth rates of fishes involved, recruitnrient, 

 and angling success. 



Creel censuses, test netting and spot-poisoning with rotenone are being 

 utilized to gather statistics on reclaimed waters. A total of 57 lakes or ponds 

 are involved in this project. 



Statewide; began September 1950, continuing; $6,000; Frank Grice, Leader; 

 reports available. 



Address inquiries to: Division of Fisheries and Game, Field Headquarters, 

 Westboro, Massachusetts. 



3. Evaluation of Fyke-Netting to Control Over -Abundant Pan and Trash Fishes 



The objective is to determine what effect pan and trash fish thinning with 

 fyke nets has on population structure, age and growth, and fishing success. 

 The effect and costs of this work will be compared to partial poisoning to 

 determine which of these methods of control are the most applicable. About 

 12 lakes comprising 1500 or more acres are involved in this project. 



Statewide; began September 1950, cintinuing; $8,000; Frank Grice, Leader; 

 reports available. 



Address inquiries to: As in No. 2 above. 



4. Evaluation of Partial Poisoning as a Method of Improving Warm Water Fishing 



Age and growth studies, species composition, and fishing success before 

 and after partial poisoning are being evaluated. In some of the ponds, game 

 fish stocking follows treatment, in others natural recruitment is relied upon 

 to fill the void created in the population. Ponds and lakes with varying species 

 compositions are being studied to assess the effect on these various popula- 

 tions. Approximately eight units involving 1100 acres are involved in this study.

1. Biology of the Larger Pelagic Fishes of the Western Atlantic 



The project is concerned especially with the tunas, marlins, sailfish, 



dolphins and carangids, particularly with their reproduction, growth from 



early stages to maturity, distribution, migrations, and feeding habits.

University of Massachusetts 



1. Management Studies on a Western Massachusetts Marginal Pond 



The objectives of this project are to furnish brown trout fishing in a pond 

 which has low priority for this species. The pond was poisoned in 1948 and 

 again in 1953 to destroy the abundant crop of suckers, bullheads and other 

 warm water fishes. The pond has been stocked each spring with brown trout, 

 and a voluntary creel census has been kept of the number of hours fished and 

 the fish taken out each year.
