1957. The skin and scales. In Margaret E. 

 Brown (editor), The physiology of fishes. 

 Metabolism 1:207-244. Academic Press 

 Inc., New York. 



The structure, chemical composition, 

 and functions of the skin of fishes and 

 of various types of scales (cosmoid, 

 ganoid, placoid, cycloid, and ctenoid) 

 are described. Sections are included on: 

 the variability in squamation; structures 

 formed by the modification of scales 

 and their function; and use of scales in 

 classifications and life-history studies.

1960a. Temperatures of Lake Michigan, 

 1930-32. U.S. Fish Wildl. Serv., Spec. 

 Sci. Rep. Fish. 322, iii + 34 p. 



Water temperatures were obtained 

 at 136 stations: June 18 to Nov. 14, 1930, 

 May 8 to Nov. 2, 1931, and April 19 to 

 Sept. 12, 1932; numbers of vertical 

 temperature series were 150 south of 

 the Frankfort- Algoma line, 58 in the 

 Lake proper above that line, and 39 in 

 Green Bay. Discussion touches on: tem- 

 perature conditions at deep and shallow 

 stations; seasonal changes of surface, 

 subsurface, and bottom temperatures; 

 the shifting of 5° C. water; and formation 

 of and gradients in the thermocline. 

 Sections of the Lake are compared.

1960b. The true pikes. U.S. Fish Wildl. 

 Serv., Fish, Leafl. 496, 9 p. 



This popular account of the genus 

 Esox contains morphological and life- 

 history notes on each species. Included 

 are such items as distribution, habitat, 

 food, maturity, egg production, spawn- 

 ing, and early development. Growth data 

 are given for muskellunge, northern 

 pike, and chain pickerel. Concluding 

 sections touch on artificial propagation, 

 commercial production of northern pike 

 and chain pickerel, and the importance 

 of the pikes in the sport fishery.

1961a. Formation of anaccessory annulus on 

 the scales of starved whitefish. Progr. 

 Fish-Cult. 23(3):135. 



Whitefish fingerlings reared from 

 fry in a large concrete tank (80 by 40 

 feet, 8 feet deep) experienced a mid- 

 summer shortage of food. Scales were 

 examined from 11 fish removed Sep- 

 tember 22. Scales of two fish gave 



no indication of midsummer slowing or 

 stoppage of growth; those of three fish 

 had a light check; two had a "fairly good" 

 annulus; the scales of the remaining 

 four had a "typical" annulus indistin- 

 guishable from those formed in a natural 

 environment.

1961b. Records, ages, and growth of the 

 mooneye, Hiodon tergisus , of the Great 

 Lakes. Trans. Amer. Fish. Soc. 90(2): 

 170-174. 



The mooneye is scarce in Lakes 

 Huron and Michigan but common in 

 Lakes Erie and Ontario. Commercial- 

 ization is limited to Ohio and Michigan 

 waters of Lake Erie; reports of com- 

 nnercial catches elsewhere are errors 

 resulting from misuse of common 

 names. In Lake Erie the total lengths 

 (inches) of certain age groups ran: I, 8.4; 

 IV, 12.2; VII, 13.1. Largest fish was 

 14.5 inches and weighed 14.8 ounces. 

 All are mature at 8.8 inches and 3.2 

 ounces.

1963. Surface currents of Lake Michigan, 

 1931 and 1932. U.S. Fish Wildl. Serv., 

 Spec. Sci. Rep. Fish. 413, ii + 51 p. 



Drift bottles released were: 283 in 

 1931 south of a line from Frankfort, 

 Mich., to Algoma, Wis.; 462 in 1932 

 both south and north of this line. Re- 

 turns were: 186 (65.7 percent) of the 

 bottles released in 1931, and 331 (71.6 

 percent) of those released in 1932. 

 Indicated surface currents were variable 

 but their general direction was from 

 west to east- -predominantly northeast 

 in 1931 and both northeast and southeast 

 in 1932.

 great difficulty of coping with the prob- 

 lem under the current system of divided
