10. Improvement of Design of Electric Fishing Gear for Collecting Fish in Large 

 Lakes and Rivers 



An attempt will be made to design electrical apparatus capable of collecting 

 young of the year game fish in shallow waters of lakes and adaptable for use in 

 quantitative fish sampling in large rivers of both hard and soft water areas.

Address inquiries to: C. R. Burrows, as in No. 9 above. 



11. Design of New Techniques and Modification of Current Methods of Fish Cultural 

 Practices as Related to Propagation of Fish and Diagnosis and Control of Fish 

 Disease 



The objectives are to develop new techniques in fish hatchery cultural pro- 

 cedures, disease diagnosis, and therapy and to test new techniques and institute 

 new methods proven by investigative work in other areas. Current work in- 

 cludes many small projects such as pelleted trout food formulation, investiga- 

 tion of sanitation conditions in hatcheries, methods of disease transmittal, in- 

 cubation period of diseases, effectiveness and degree of dispersal of medica- 

 tion in trout food and design of trout distribution units for higher survival.

12. Investigation of Possible Differences in Blood Physiology Between the Two Sexes 

 of Ameiurus sp. 



The objective is to get an almost complete blood picture of one species. 

 Preliminary work only has been conducted primarily on the estimation of 

 blood volume, sedimentation rates, coagulation time, and blood cell counts.
