The Relation Between Insect Prevalence and the Abundance 
of Fish in aapryees and Unimproved Stream, Pond and Lake Areas. 
To determine (1) correlation, if any, of numbers and kinds of 
insects in trout streams to distribution and variation in trout 
population and factors concerned, and (2) insect fauna, effect 
of various treatments, fertilization, depth of water, periodical 
draining, fish population, and other factors on insect population 
in fish ponds. 
Ent. 27 
Farm Fish Pond Management. To (1) estimate production of 
plants and animals per unit area or volume of water in farm type 
ponds and natural ponds, (2) determine to what extent fertiliza- 
tion of ponds will increase production of fish food and fish, 
(3) devise practical management programs for farm ponds, and (4) 
detect and measure possible detrimental effects of use of ferti- 
lizers in fish ponds.

Physiologic Response of Aquatic Organisms to Pollutants . 
To (1) determine physiological cause of death in aquatic animals 
most susceptible to pollutants, and establish symptoms of sub- 
lethal amounts of pollutants, (2) demonstrate and identify re- 
sponses which may be interesting, but insignificant, for death, 
as opposed to those which have value as diagnostic symptoms of 
pollution toxicity, and (3) measure influence of environmental 
variables on above responses and determine validity of findings 
in predicting population changes in habitats subjected to 
pollution.

Studies _on the Farm Fish Pond in New York State . To deter- 
mine (1) how valuable as fish producers, farm ponds may be under 
New York conditions; (2) factors which favor or hinder the produc- 
tion of valuable fishes in such ponds; and (3) to test and demon- 
strate successful pond fish management methods.

A Study of "Native" Oyster, Ostrea Lurida, Farming in Oregon, 
as_a Supplementary Agricultural Enterprise. To determine (1 
present and past status of oyster farming as a supplementary agri- 
cultural enterprise; (2) available unproductive lands which may be 
developed into oyster farms; (3) methods for preparing tidal lands 
for oyster farming; (4) maintenance of prepared lands; (5) costs 
of preparation; and (6) amount of land required for an economic 
part-time farming unit.
