1953 . Technique for the application of a 



streamer-type fish tag. Trans. 



Am. Fish. Soc, Vol. 82(1952), 



pp. 42-47. 

 Principal features of the technique 

 are: attachment of tag by a nylon - 

 thread loop prepared in advance of 

 field work; application of tag by means 

 of a curved surgical needle with a 

 cutting edge and a split eye. Prepara- 

 tion of needle and tagging procedure 

 are described. 



1957. Structure and growth of scales of 



yellow perch of Green Bay. Trans. 

 Am. Fish. Soc, Vol. 86(1956), 

 pp. 169-194. 

 Scales are described and their use 

 for age determination validated by 

 comparisons of ages of younger fish 

 or read from scales and estimated 

 from modes in length distribution. 

 Annual and local variations in the time 

 of annulus formations are described. 

 Body-scale curves are presented for 

 "key" scales above and below the 

 lateral line. Body -scale curves based 

 on the same key scale are compared 

 for yellow perch of Lake Erie, Saginaw 

 Bay, and Green Bay.
