was correlated positively with tem- 

 peratures in June and September 

 (terminal months of the growing sea- 

 son) and with precipitation in June . 

 The strength of year classes was cor- 

 related positively with temperature 

 and precipitation in May, June, and 

 July. Other topics treated include: 

 criteria for testing validity of annulus 

 as a year -mark; sex and age differ- 

 ences in progress of season's growth; 

 growth compensation as a real and 

 as an "apparent" phenomenon; rela- 

 tion of growth rate to size and age at 

 maturity; annual and seasonal fluctua- 

 tions in the length -weight relationship; 

 sex ratio . 



1942. Growth of the rock bass, Ambloplites 

 rupestris (Rafinesque) in five lakes 

 of northeastern Wisconsin. 



Trans. Am. Fish. Soc, Vol. 71 



(1941), pp. 131-143. 

 Comparison of growth and length - 

 weight relationship in different popula- 

 tions. Growth curves of rock bass 

 from lakes with medium -hard to hard 

 water were more distinctly sigmoid 

 and had larger increments in later 

 years of life than curves for stock 

 from soft -water lake. Order of the 

 stocks with respect to relative heavi- 

 ness followed the order of the lakes 

 as to hardness of water. 



1943. Mathematical relationship between 

 the length and the age of tlie rock 

 bass, Ambloplites rupestris 

 (Rafinesque). Pap. Mich. Acad. 

 Sci., Arts, and Lett., Vol. 28 

 (1942), pp. 331-341. 



Derivation of equation on the assump- 

 tion that annual percentage growth in 

 length decreases at a constant per- 

 centage rate, and application to growth 

 of two stocks of rock bass. Equation, 

 L = K (CB + 1) (GB^ 1) (CBS5-+ 1)- • • 

 (CB'^+ 1), where L = length, ^= age 

 in years, and K, C, and B = constants 

 fitted growth of one stock through 9 

 years of life; in another the equation 

 fitted over 6 years but yielded values 

 that were too high for the seventh, 

 eighth, and ninth years.

1948 . Standardization of methods of ex- 

 pressing lengths and weights of 

 fish. Trans. Am. Fish. Soc, 

 Vol. 75 (1945), pp. 157-164. 



Recommendation for uniform use of 

 total length (tip of head, mouth closed, 

 to tip of tail, lobes compressed) and 

 for English units of weight and measure- 

 ment (with decimal fractions) in all 

 but highly technical papers.

Review of available statistics on pro- 

 duction, 1879-1946, and detailed 

 treatment of annual fluctuations in 

 production, abundance, and fishing 

 intensity in local districts of the 

 U.S. waters, 1929-1946, with special 

 reference to the decline that followed

 the scientific investigation of the 

 marked increase in abundance of 

 walleyes in Green Bay. The Fish- 

 erman, Vol. 18, No. 3, pp. 5-6. 



Popular discussion pointing out: that 

 the abnormally hig^ abundance could 

 be traced almost entirely to a single 

 year class (1943); that a return to a 

 much lower level could be considered 

 inevitable; and that restrictive regula- 

 tions, intended to perpetuate the 

 abnormal abundance would prove dis- 

 appointing and would place unnecessary 

 handicaps on the fishing industry.

 the growth of fish from scale meas- 

 urements. Trans. Am. Fish. Soc,

 Description of a device usable for rapid
