perch eggs again destroyed in the 63-acre lake. 



Specific lakes; began March 1953, to close November 1957; $500; Alban R. 

 Essbach, Leader; reports available. 



Address inquiries to: Alban R. Essbach, New Jersey State Fisheries Labora- 

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



10. Population Manipulation 



The biological changes brought about by manipulating populations will be 

 measured by creel census, analysis of growth, and changes in population as 

 shown by net catches. 



Statewide; began March 1953, to close 1957; $7,000; Alban R. Essbach, 

 Leader; reports available.

11. Introduction of New Game and Panfish Species 



The objective is to attempt to establish the striped bass (Roccus lineatus) 

 in several lakes. The major purpose is to provide an additional predator large 

 enough to utilize the large golden shiners and miscellaneous fishes. 



The channel catfish will be used in park ponds where they should be 

 easier to manage and more desirable than other game and pan species. The 

 redear sunfish will be utilized in small impoundments as more desirable be- 

 cause of its low reproductive potential and larger size. 



Central and northern New Jersey; began May 1953, indefinite; $1,000; 

 Alban R. Essbach, Leader; reports available. 



Address inquiries to: Alban R. Essbach, as in No. 10 above. 



12. Introduction of New Forage Species 



The objective is to investigate the possibility of introducing forage species 

 that would be available as forage throughout their life span, non-competitive 

 to game fish, and prolific and abundant. 



The saltwater spearing and anchovy have become landlocked in two fresh 

 water impoundments and their potential as forage will be investigated. Land- 

 locked herring are common in larger New Jersey lakes and will be stocked in 

 smaller impoundments and weedy lakes where they do not now exist. Fresh- 

 water shrimp have been found in a specific watershed and are being investiga- 

 ted as an intermediate food for bass fry at the State Fish Hatchery, and as forage 

 in ponds . 



Statewide; began May 1953, indefinite; $300; Alban R. Essbach, Leader; 

 reports available. 



Address inquiries to: Alban R. Essbach, as in No. 10 above. 



13. Pickerel Ice Census 



The objectives are: (1) To evaluate the effects of the 15-inch minimum size 

 limit on pickerel in those lakes where it has been adopted; (2) to obtain routine 

 population and fishing statistics on pickerel from several heavily fished lakes; 

 and (3) to obtain census data on yellow perch and other species taken through 

 the ice. 



Northern New Jersey lakes; began January 1950, to close January 1958; 

 $1,000; Roland F. Smith, Leader; reports available. 



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