Life-history and distributional study based on 1930-i9?'< 

 collections by experimental gill nets„ Reighard's chub spawned 

 in May and June at 20-79 fathoms; in other months was most> plenti- 

 ful at 20-60 fathoms. Abundance or. east shore of lower half of 

 lake was seven times that on west shore and three times that in 

 northern pai-t of lake. Age -group IV (average length 10 „ 9 inches^ 

 average weight 6ol ounces) dominated samples. Females outnumbered 

 males and survived to greater age.

Study of distribution from. 1930-1932 collections from ex- 

 perimental gill nets and of grow+.h from earlier (1919 and 1928) 

 collections from Grand Haven^ Michigan, Bloaters were most plenti- 

 ful at 20-^9 fathoms (with the larger fish in the deeper water in 

 some months); abundance on east shore of lower part of lake was 

 one and one-half times that on west shore and two and one-third 

 times that in northern part of lake. Samples were dominated by 

 age-gx-oup IV in 1919 and (weakly) by age-group II in 1928, Growth 

 was slightly more rapid in females than in males but was slow in 

 both sexes (barely 8 inches in ^ years). Females outnambered 

 males. 



19U9o The age, growth, and distribution of the longjaw cisco, 

 Leucichthys alpenae Koelz, in Lake Michigan. Trans, 

 Am, Fish, Soc,, Vol, 76 (I9ii6), pp, 21^-2li7o 



Study of distribution from 1930-1932 collections from ex- 

 perimental gill nets and of growt.h from earlier (1923 and 1928) 

 colleotions, Longjaw was most plentiful at less than 70 fathoms 

 and more than four times as abundant in northern part of lake 

 and along ea-st shore as on west shore of lower lake. Samples 

 were dominated by age-groups III or IV, Growth was siiailar off 

 Grand Kaven, Michigan, and in northeastern Lake Michigan (average 

 length about 11 inches and average weight about 6 l/ij. oun,:.es at 

 ena of U year-s). Sex rar-io xiras variable but females generally 

 outnumbered males and reached higher ages.
