5. The Life History and Ecology of Gizzard Shad in Lake Erie. 



The gizzard shad is near the northern limits of its distribution in Lake Erie, 

 and it finds marginal conditions for existence. Its numbers fluctuate from very 

 low to very great with regulation by some factors of the environment. The gizzard 

 shad is an important food item for most of the fish-eating fishes, so its variations 

 of abundance affect the entire economy of the lake.

1. The Effects of Artificial Feeding. 



The objective of the project is to determine the relative growth of bluegills 

 in a natural pond, in a fertilized pond and in a pond where natural fish food was 

 supplemented with soybean meal and ground carp.

2. The Life History of the White Crappie of Buckeye Lake. 



The project objective is to learn as much as possible of the complete picture 

 of the life of the white crappie from fertilization of the egg until death. It in- 

 cludes the description of the species, distribution, school movements, associa- 

 tions, reproduction, attainment of sexual maturity, spawning and nesting habits, 

 egg production, embryonic, larval and post larval development, growth and 

 weight relationships, formation of annuli, the plumpness or K values, food habits 

 and parasites and diseases.

1. Farm Pond Studies. 



Fifteen ponds at U. S. Fish Cultural Station, Hebron, Ohio, and 54 additional 

 ponds under private control in surrounding counties are being utilized and studied. 

 Six types of test-stocking involving bass and bluegills are now in progress. Futur 

 combinations will involve redear sunfish and bass, and golden shiners with bass. 

 Pond food organisms and general plankton conditions are also studied.
