2. Experimental Stocking of Walleye in a Texas Impoundment. 



Devils Lake near Del Rio, Texas, has been examined and findings indicate a good 

 possibility for survival, and possibly reproduction of walleye. It is intended to 

 stock this lake with one-half million walleye fry in 1953.

1. Biochemistry of the Gulf of Mexico (Proj. 67). 



As a means of delimiting potentially productive fishing areas, an effort is being made 

 to establish the distributions and concentrations of nutrients and the relation be- 

 tween these nutrients and the distributions and concentrations of fishes.

2. Biological Inventory of the Gulf of Mexico (Proj. 68). 



The objective of this project is to define the identity, abundance, distribution, and 

 interrelation, of the various plankton forms and the relation between the varia- 

 tions within these to the distribution, availability and fluctuation of the fishes.
