5. Acid Water Studies 



This project involves studies on highly acid waters including the possibility 

 of establishing sea-run trout populations in certain coastal streams, fertiliza- 

 tion and alkalization of streams and impoundments, improvement of substrate 

 of stream bottoms, and studies on fertility and productivity. 



Southern New Jersey; began 1952, indefinite; $500; Roland F. Smith and 

 A. Bruce Pyle, Leaders; reports available. 



Address inquiries to: Roland F. Snnith, as in No. 4 above. 



6. Poll of License Holders 



The objective is to develop a technique of censusing holders of New Jersey 

 fishing licenses that will enable the securing of data or trends pertaining to 

 fishing success, fisherman preferences, and habits. 



Statewide; began 1955, indefinite; $2,000; Philip Crutchfield, Leader. 



Address inquiries to: Philip Crutchfield, New Jersey Fisheries Labora- 

 tory, 126 North Main Street, Milltown, New Jersey. 



7. Statewide Creel Census 



The objectives are: (1) To obtain data relative to harvest, fishing effort, 

 species composition, along with rainfall, temperature, surface activity, etc., 

 that may be employed to provide time contrasts on a series of warm water 

 non-acidotrophic New Jersey lakes; (2) to establish a mean trend in fishing 

 effort, species composition, and total effort over a period of years; (3) to 

 locate those lakes, or areas where the harvest and/or fishing effort is changing 

 relative to the mean trend; (4) to provide a basis for measuring the success or 

 failure of certain management techniques that might be tried, for example, 

 stocking; and (5) to locate lakes where "real" declines in the standing crop of 

 any given species are being experienced and, perhaps equally important, 

 to objectively elinciinate situations wherein troubles are reported to exist but 

 which, in fact, do not. 



Statewide; began 1955, indefinite; $6,000; A. Bruce Pyle, Leader; reports 

 available.

8. Distribution of Fishes in New Jersey 



A general survey of the species of fishes present and their distribution 

 in the State. 



Statewide; began 1950, indefinite; Roland F. Smith, Leader; reports 

 available.

9. Destruction of Fish Eggs Through Use of Chemicals 



The objective is to test the feasibility of pan fish control through destruc- 

 tion of their eggs with chernicals. Preliminary tests indicate that copper sul- 

 fate will kill common sunfish eggs in 10 minutes when a large crystal is 

 dropped into the nest depression. Yellow perch eggs were destroyed to a 

 lesser degree by using a combination of copper sulfate dust for suspended 

 masses and crystals for egg masses on the bottom. It was estimated that 

 85 percent of perch eggs were destroyed in a 63-acre pond and subsequently 

 no young-of -the -year were found during summer and fall rotenone sampling. 

 Common sunfish nests will be destroyed on at least two park ponds and yellow
