INTRODUCTION
Palestine Lake, located in Kosciusko County, Indiana, is a shallow lake where
maximum depth is 30 feet and average depth is only 4 feet (Figure 1). This lake suffered
a winterkill in 1978, which allowed undesirable fish, such as carp and gizzard shad, to
become the dominant species (Braun 1991). By 1982, these fish had also migrated into
Caldwell Lake and, consequently, dominated both lake populations (Kittaka 2000). Once
these species were abundant, the game fish populations were unable to recover in
number, and as a result, rotenone was applied in 1988 to the lake, its tributaries, and
Caldwell Lake to remove fish. Restocking of largemouth bass, bluegill, redear sunfish,
and channel catfish occurred in the fall of 1988 and length limits were imposed on both
lakes in order to protect the fish from harvest and enable the establishment of a sizable
population (Table 1). In addition, northern pike were stocked into Palestine Lake in
1991, 1993, 1994, and 1995, and muskellunge were stocked in 1997, 1998, 1999, 2002,
and 2003.

A general fish population survey was last conducted in Palestine Lake in 1999
and showed a population structure that was different from the one expected based on
previous stocking efforts (Kittaka 2000). During the 1999 survey, gizzard shad were
second in abundance to bluegill. In addition, the largemouth bass only accounted for 4%
of the catch, but age-1 fish were captured which did indicate some recruitment.

In contrast, age-0 and age-1 redear sunfish were not captured, indicating poor recruitment
of this population. No muskellunge or channel catfish and only six northern pike were
collected during the 1999 survey. This general survey of the population of fish in
Palestine Lake is necessary to evaluate changes in the population that may have occurred
in the past few years and determine management strategies that may be necessary to
improve the game fish populations within the lake.
RESULTS
A total of 930 fish consisting of 15 species and one hybrid were captured from
gill nets, trap nets, and night boat electrofishing in the east and west basins of Palestine
Lake (Table 2). The total weight of all captured fish was 347.81 lbs. The most abundant
fish species in the lake were bluegill, largemouth bass, black crappie, gizzard shad, and
golden shiner. The least abundant fish in this lake were pumpkinseed, yellow perch,
3

redear sunfish, white sucker, brown bullhead, yellow bullhead, hybrid bluegill, channel
catfish, and green sunfish. Of the six species of fish stocked into Palestine Lake (bluegill,
largemouth bass, redear sunfish, channel catfish, muskellunge, and northern pike), only
four of these were captured during the survey. The other species collected were not
stocked by the Department of Natural Resources.

Bluegill was the most abundant species captured and comprised 54.7% of the total
catch (N = 509). These fish ranged in size from 2.1 to 8.7 in and had a batch weight of
4
20
87.91 lbs (25.3% of total weight). Captured bluegills were ages 1+ through 8+ and
growth for these fish was average. The PSD for bluegill in this lake was 55.4 and the
RSD-8 was 16.7.
Largemouth bass (length range, 5.7 to 18.3 in) were second in abundance based
on total catch (N = 109; 11.7%). However, this species comprised the largest percentage
by weight (91.06 lbs; 26.2%) overall. Largemouth bass in this lake were ages 1+ through
9+. No age-7 largemouth bass (year-class 1996) were captured during this survey.
Growth of these fish was slightly above average. The PSD for largemouth bass in this
lake was 33.0. The RSD-14 was 28.6 and the RSD-18 was 1.1.
Black crappie were the third most abundant species by catch (N = 106) despite not
being stocked into the lake, and represented 11.4% of the total number of fish captured
during the survey (length range, 5.9 to 12.6 in). However, this species comprised only
7.4% of the total weight of captured fish (25.68 lbs). The black crappie ranged in age
from 2+ through 6+. No age-1 or age-5 fish were collected. Growth of these fish was
slightly below average.
Gizzard shad (N = 74) were the fourth most abundant species based on total catch
(8.0%). In contrast, this species was the third most abundant based on percent weight and
comprised 23.2% of the total weight captured from the lake (80.60 lbs) even though they
were not stocked. These fish ranged in length from 12.7 to 15.7 in.
Golden shiners made up 7.8% of the total catch (N = 73). These fish weighed
only 1.6% of the total weight of fish (5.48 lbs) captured during the survey. Eleven other
species were collected including two stocked and nine unstocked species.
Water quality was determined for both the east and west basins of Palestine Lake.
In the east basin, surface dissolved oxygen (DO) was 8.8 ppm (parts per million),
whereas in the west basin, surface DO was 12.0. Adequate oxygen levels for fish were
not present below 8 ft in either the east or west basin. The color of the water was
greenish-brown and the secchi disk readings were 3 ft, 4 in for both basins. Low secchi
readings may indicate water that is too turbid to allow efficient feeding for sight-feeding
species such as largemouth bass.
Vegetation sampling resulted in the identification of 8 different species of
submerged, emergent, floating, and shoreline vegetation, including coontail, spatterdock,
5
20
arrowhead, duckweed, water meal, cattails, purple loosestrife, and water willow (Table
3). The dominant algae found during this survey was pithophora. Coontail was the
dominant submerged vegetation, and water meal and duckweed covered most of the
sampled area.
DISCUSSION
The population structure of fish in Palestine Lake has only slightly changed since
this lake was last surveyed in 1999. The total number of fish captured in 2003 was less
than half of what was captured during the same amount of sampling effort in 1999
(Kittaka 2000). Three game species, bluegill, largemouth bass, and black crappie,
dominated the fishery, unlike 1999 when bluegill, gizzard shad, and pumpkinseed were
the most abundant species in the lake. Although bluegill were the most abundant species
collected during both the 1999 and 2003 surveys, the PSD and RSD-8 of those fish were
higher in 2003. In addition, the largemouth bass population in 2003 had a higher PSD
and comprised a larger percentage of the total number of fish captured than in 1999,
indicating that this fishery may be steadily improving each year. The RSD-14 and RSD-
18 values for largemouth bass were similar between the 1999 and 2003 surveys. Fewer
gizzard shad were collected during this survey and all fish ranged in size between 12.7
and 15.7 in, so predators such as largemouth bass may be utilizing small gizzard shad as a
prey resource. Black, brown, and yellow bullhead, as well as channel catfish are still
found in Palestine Lake, however, their numbers remain low and they comprise less than
3% of the total number of fish found in this lake. In addition, no carp were collected
during the 2003 survey, whereas in both 1997 and 1999, carp were captured from the lake
(Braun 1997; Kittaka 2000). Therefore, it appears that carp are not an important
component of the fishery in Palestine Lake at this time.
Although muskellunge were last stocked in Palestine Lake in 2003, and northern
pike in 1995, none of these fish were captured during the 2003 survey. This is an
indication that stocking efforts in this lake were unsuccessful in establishing naturally
reproducing populations. In addition, muskellunge in this lake do not appear to survive
for long after stocking has taken place, either migrating over the dam or dying at high
water temperatures in the summer. Based on these data and previous surveys, continued
6
20
stocking of this lake will not produce a naturally reproducing population, possibly due to
a limitation in suitable habitat necessary for their survival (i.e., high water temperatures
and low DO at depths less than 8 ft) and the muskellunge fishery in this lake will
continue to be hatchery-based (Kittaka 1999).
RECOMMENDATIONS
General fisheries surveys should continue to be conducted periodically in this lake
in order to evaluate changes that occur in the game fish populations and monitor the
gizzard shad abundance. In addition, the heavy vegetation and low DO levels in this lake
should be addressed and investigated with the assistance of the lake association in order
to further improve water quality and consequently, the game fish fishery. Further,
muskellunge should continue to be stocked into this lake in order to maintain a
productive fishery for this species.
