Coeparieon of present study
Iith other licnigen.leraemouth base

The growth.rste or the fish in the present study equals
or exceeds that inplied in previous studies or the large-
Iouth bees in Iichigan.

Bedknen (l949) conpiled average weights and lengths for
variaus are groups or the larceeouth base in Michigen. The
information given is for the entire state. and for an
indefinite period. These data do not lend themselves readily
to con,erisons with the hintersreen Lake data which are for
a specific lake. and definite yeriods. with each collection
yeriod yresented independently. however. the data are given
on pece 75. table l7. In his study Beehen (1948) found e
legal largeeouth bass in kichiaan (ten inches or twenty-five
centimeters) to be four summers old. The fish in the (resent
study attained this length shortly after the {creation of
the second annulus. This illustrates the superior growth
rate for fish from fiintergreen Lake.

Eben-ever (1939).eonpered the growth of lergenouth bass
in.aowe Lake with those.tron other eetsre including Winter-
green Lske. uis tables (converted from inches to centimeters.
no. 15) are presented. with a comparison of average mean
calculated values or fiintergreen Luke fish collected during
1961. The lengths of the Wintergreen Lake fish or lgtl used

in this comparison are those observed at the time or denture.

Each-eyere. (1939) in.raferrin5 to the Bone Lake data. aaya
'....aince the fiah were taken in early September they were
actually older in terns or growth than ia indicated; the fish
or the I age group (I annulua). for example. had completed
the greater part of their aecond growing aeeaon.‘ One ahould
be aware or thia difference when comparing the two studies.

The congarieon or rate or growth for fish collected
from .‘ulntersx‘een Lake during 1951 with Eechneyer'a (1933)
table. ahow that the fiah in the present atudy are above
average» The only tiah having a greater growth rate. than
that found in thia study. are from acuthcrn Wiaoonain.

Aa previoualy mentioned. the valuea for lengtha or
fiah from wintergreen Lake 1939 and from flataon Lake. ea
given by Eachneyer. were actually higher then.yeerly averages
should have been. It is apparent. from a comparison of data
nfrom the two atudlea (table 18). that the Wintergreen Lake
fiah were growing more'rayidly during the 1961 collection
than they were when Each-eyer'a data were taken from the
eene lake.

Conclusion

Wintergreen Lake. Kalanasoo county. Michigan is a eutrophic
lake rich in.nntrients as evidenced by the abundance of
cladooerens and other small crustacea. and a heavy phytOplaz-Jcton
blooa. The growth rate of the largencuth base in this lake.
as revealed by the present study. was found to be greater than
that of comparable fish in Hichigan. The rapid growth of
these fish may be accounted for. in part. by the abundance
of forage fish.

The collection of data was from January 1961 through
August 19:1; of this period. the month of greatest increment
iu.5rowth is January. while the month or aaxinua lengths and
weights for any age grOUP is April.

A quantitative methoc for determination of time of annulus
formation is presented. based on age group II collection for
April having maximum weights and lengths. while the Hay
collection. which includes the period of annulus formation.
has minimu- weishts and lengths.

The graphs (figures 6 and 7) of the calculated lengths
(as given.in table 16) show the “classic” growth pattern: a
very rapid rate during the early years of life. with a
gradullli dOOPOOlins ”I‘0 83 the G60 increases. In general.
the growth rate as revealed by this study exceeds that of
cOMparabie fish for the early years (until the fourth annulus).

while the others have a more rapid growth for the older ages.

Reduced acrtality (due to limited fishing) among the older
age groups would result in greater competition; this may
explain their sharp decline in growth rate. Even though
the growth rate of the older age groups in.tnis study is
less. the total lengths and weights remain larger than for
coaparable Hichigan fish. due to the very rapid growth of

younger age groups.
