12. Atlantic States Cooperative Striped Bass Program 



The several states are investigating local problems which involve inventory, 

 catch and effort, location of spawning grounds, movements of local populations, 

 physiology, growth and early life history, ecology, survival of young, sex 

 ratios, food, populations estimates, effects of pollution, etc. In the coordinator's 

 laboratory, studies of racial structure, especially of the subpopulations in 

 Chesapeake Bay, using fin ray, scale, gill raker counts, morphometric 

 characters, and scale characters, continue. General studies of migration 

 as determined by tagging are also under way.

1. Vitamin Requirement of Trout 



The objectives are: (1) To determine the vitamin requirements of trout 

 and the symptoms of deficiencies by means of vitamin test diets and micro- 

 biological assays (2) to improve the health, increase the rate of growth, and 

 lower the cost of producing hatchery trout.

 Leader; reports available.

 Service, Cortland, New York. 



2. Development of Practical Diets for Trout 



The objectives are: (1) To determine the value of various dietary mixture 

 in terms of growth, cost of production and mortality of the fish. (2) To deter- 

 mine the effect of dietary mixtures upon the body chemistry of the trout.

 reports available. 



Address inquiries to: Arthur M. Phillips, Jr. , as in No. 1 above. 



3. Use of Radio-active Isotopes in Trout Nutrition Studies 



The objectives are to study the absorption, utilization, and retention of 

 nninerals dissolved in the water and/or present in the diet and their role in 

 trout nutrition and physiology. 



New York Conservation Department and Cornell University cooperating; 

 Cortland, began July 1951, continuing; Henry A. Podoliak, Leader; reports 

 available. 



Address inquiries to: Arthur M. Phillips, Jr. , as in No. 1 above. 



4. The Chemical Comparison of Hatchery and Wild Fish Food 



The objectives are to chemically compare hatchery and wild food and 

 trout reared upon each type. From this information the effectiveness of 

 hatchery food in terms of natural food is to be measured. From these data 

 an attempt will be made to improve hatchery diets.
