1.0 Introduction
This report presents regional summaries of life history characteristics of walleye
(Stizostedion vitreum vitreum) populations from 390 Ontario lakes and large
rivers. These waterbodies were sampled between 1993 and 2001 using the fall
walleye index netting (FWIN) standard (Morgan 2002). The results for each
region are presented as tables which describe the waterbody characteristics and
the following walleye biological attributes:
- relative abundance
- annual adult mortality by sex
- weight-length relationship and condition by sex
- length-at-age by sex
- weight-at-age by sex
- growth by sex
- sexual maturity by sex
- relative fecundity
- fecundity-length relationship
- reproductive condition by sex
All data used in this report were derived from FWIN projects submitted to the
Cooperative Freshwater Ecology Unit, Laurentian University and archived by the
Ontario Ministry of Natural Resources (OMNR). These data were entered,
archived, and managed using the OMNR FISHNET software package (Lester et
al. 1989). Only data that were collected using the FWIN standard and managed
by FISHNET are included in the regional summaries.
FWIN was first operationally tested in 1993 with pilot studies at Lac des Mille
Lacs (OMNR northwest region) and the French River (OMNR south-central
region). Since that time, the number of projects increased yearly (Table 1).

The large number of FWIN projects in the northwest region in 2000, the northeast
region in 1999 and 2000, and the south-central region in 2001 were related to
pilot “status of resource” studies and regional fisheries management initiatives.
The provincial FWIN database contains 442 completed and archived FISHNET
projects from 390 different water bodies. Almost three-quarters of the FWIN
projects (and waterbodies) were in the northwest and northeast region (Table 2).

The life history characteristics and benchmarks summarized in this report are
intended to be a source document for area biologists responsible for managing
their walleye resource. These provide a means of comparing the results from
individual populations of interest to other populations within the region or in other
regions across the province. For any waterbody, where a standard FWIN survey
has been conducted, a rapid, point-in-time assessment of the walleye population
status is possible by comparing measured variables with known reference
values.
In this report, we derive reference values (i.e., regional benchmarks) to
encourage this type of assessment. Results of future sampling efforts can be
compared against these walleye benchmarks for key life history parameters. We
believe that these benchmarks would be useful to many walleye biologists
because it permits them to look at their particular populations in the context of
Ontario walleye populations generally.
These benchmarks represent the
average values along with some measures of variability from a large set of
Ontario waterbodies, widely distributed across the province (Figure 1). The
regional benchmarks are organized in a series of 11 tables. The provincial
benchmarks are summarized in one table (Table 12 which is included at the end
of each regions benchmark tables). Data from a project was excluded from a
table if any of the required data fields were missing or estimators could not be
calculated. (i.e., the number of fish sampled was too small). At the end of each
table are summary statistics for comparative purposes (i.e., the regional
benchmarks).

which fall walleye index netting data were available.
2.0 The FWIN Database
The master FWIN database was created through a unique combination of
FISHNET files and compendium output (Kushneriuk 1996). Data from individual
FISHNET files were stored in ACCESS® while the compendium output files were
compiled by project and stored in ORACLE®. Automated data transformations
were performed in ORACLE® to create the final working tables (e.g., the reordering of male, female, and combined sex data). All ACCESS® and ORACLE®
tables were combined into a new master FWIN database where querying of the
data occurred to create the regional benchmark tables.
Each life history character was estimated using a consistent set of defendable
methods. Many of these life history parameters are related to fish age so every
effort has been made to ensure consistent tissue collection and age
interpretation. Calcified structures collected from the FWIN projects over the
years varied across the province. Whenever possible the sagitta or otolith was
the first choice for walleye age interpretation. The method used to prepare the
otoliths was the crack and burn technique described by Christensen (1964).
Annuli were very distinct for age interpretation, especially for very old fish
compared to the dorsal spine or scale methods. If no otoliths were collected, the
next preferred structure for age interpretation was the dorsal spine. The spine
was coated with a two-part epoxy and then sectioned along the transverse plane
at the base of the structure. Age interpretation was difficult for very old walleye
due to piling of annuli along the edge of the structure. Scales were only used for
very young fish (during their rapid growth period and before sexual maturation).
Scales were impressed into acetate slides and interpreted in a microfiche reader.
The Northwest Science and Information Ageing Lab in Dryden, Ontario prepared
and aged over 95% of the total projects in the FWIN database.
3.0 Parameter Estimation and Table Format
3.1 Basic Waterbody Descriptors (Table 1)
Various attributes of the waterbodies were listed alphabetically. Latitude,
longitude, surface area, mean depth, maximum depth, and Secchi depth were
derived from the Aquatic Habitat Inventory Database (contained in FISHNET) or
updated from information provided by OMNR area biologists. Climate was
characterized by growing-degree-days above 5oC which was estimated for each
individual waterbody from the Ontario climate model (Mackey et al. 1996). The
regional benchmarks did not include projects where only a portion of a waterbody
was sampled. A map of the waterbodies sampled in each region from 1993 to
2001 is provided (Figures 2 to 4).

3.2 Relative Abundance (Table 2)
The average catch or relative abundance of walleye caught, standard error,
sample size, number of nets that caught walleye, and the average size of the
walleye caught (expressed as total length in mm and wet weight in grams) from
each project were recorded in this table and arranged by waterbody name in
alphabetical order. The relative abundance reported was the geometric mean
(i.e., the average of the logarithmically transformed (base 10) individual
observations increased by one). For any waterbody that had been sampled in
more than one year, data from the most recent year was used as input for
deriving regional benchmarks.
3.3 Mortality (Table 3)
Observed female (Table 3a) and male (Table 3b) annual adult mortality was
described by the Robson and Chapman estimator for fish age 5 and older
(Robson and Chapman 1961, Ricker 1975 p. 31):
S=
T
ȈN + T - 1
where S is annual adult survival, T = N1 + 2N2 + 3N3…, N = N0 + N1 + N2 +…,
and N is the number of fish whose age is greater than or equal to age 5.
Annual adult mortality (A), the proportion of fish that dies in one year, was then
calculated as A=1-S and expressed as a percent. A regression analysis
indicated that the combined sex estimate was a good predictor of female and
male mortality and we used these results to generate additional female and male
estimates. The tables were arranged from low to high values using the estimated
total annual mortality. The regional benchmarks were derived using all the data
(including multiple years from an individual waterbody).
3.4 Weight-Length Relationship and Condition (Table 4)
These tables give estimates of weight-length parameters for females (Table 4a)
and males (Table 4b) based on a geometric mean predictive regression model
fitted to logarithmically transformed (base 10) individual observations of wet
weight (grams) versus total length (mm).
log W = log D + E log L
10
10
10
where W is wet weight in grams, Į is the intercept, ȕ is the slope, and L is total
length in mm. The equation presented in the table is W=10ĮLȕ.
5
Only projects with 30 or more observations, a correlation coefficient greater than
or equal to 0.90 (i.e., R20.90), and having their derived regression models with
slopes and intercepts significantly different from 0 (p<0.05) were included in
these tables. Values were sorted from low to high using the slope parameter (ȕ).
The regional benchmarks were derived using all the data (including multiple
years from an individual waterbody).
Condition was calculated as the arithmetic average of the individual ratios of
observed wet weight-to-predicted wet weight. Observed wet weight was the
actual weight recorded in the FISHNET file. Predicted wet weight was derived
from each regions median regression model (i.e., the regional weight-length
benchmark relationship) by estimating the wet weight of a walleye based on the
observed total length in the FISHNET file.
3.5 Length-at-Age (Table 5)
Total length-at-age data are presented for females (Table 5a) and males (Table
5b). Only arithmetic mean values with a minimum sample size of 4 individual
observations or more were included in these tables. Values were sorted from
low to high using total length-at-age 1, 2 and 3. The regional benchmarks were
derived using all the data (including multiple years from an individual waterbody).
3.6 Weight-at-Age (Table 6)
Wet weight-at-age data are presented for females (Table 6a) and males (Table
6b). Only arithmetic mean values with a minimum sample size of 4 individual
observations or more were included in these tables. Values were sorted from
low to high using total weight-at-age 1, 2 and 3. The regional benchmarks were
3.7 Growth (Table 7)
The growth parameter tables (Table 7a for females and Table 7b for males)
reports results from a parameter constrained growth model based on an
empirical method of fitting the Von Bertalanffy growth equation:
L t = L෱ (1 e
K (t to )
)
where Lt is total length in mm at age t, L is asymptotic total length in mm, K is
the Brody growth coefficient (i.e., relative growth rate), and to adjusts the time
6
scale to incorporate a non-zero length at age=0. The value of to was constrained
as -1.
Kushneriuk et al. (1996) expanded on the ideas of Pauly (1984) and Payne et al.
_
(1990) to estimate asymptotic length using the geometric mean length ( L ) of the
largest p% of the fish in a sample, where p is a variable that depends on sample
size. Asymptotic length was estimated using:
Lf
_
L(1.0732 0.0223 p - 0.0006 p 2 )
where p is the sampling fraction expressed as a percent. A 1% sample was used
wherever the total number of fish aged by sex was greater than 500. For smaller
sample sizes, the largest 5 fish and the above formula was used to estimate L.
Omega (Ȧ) is early growth and corresponds to the growth rate near to (and is
calculated as K•L) (Gallucci and Quinn 1979). Pre-maturation growth (h) was
defined as the growth rate to 350mm total length for combined sexes (Lester et
al. 2000).
h=
350mm
T350 + 1
where T350 was interpolated from mean total length in mm of the two consecutive
age groups whose lengths bounded 350mm.
Values were sorted from low to high using L. The regional benchmarks were
3.8 Maturity (Table 8)
Maturation was visually assessed by internal examination of the gonads from
individually sampled fish (Duffy et al. 2000). Logarithmically transformed (base
10) age and size-at-maturity schedules (i.e., the percent mature at age or length)
were fitted to a logistic regression function for each population. Age and size at
10, 50, and 90% maturity were then derived from the equation. The data was
arranged from youngest to oldest age-at-50% maturity. Results are presented
for females in Table 8a and males in Table 8b. The regional benchmarks were
7
3.9 Fecundity (Table 9 and 10)
Mature ovaries were collected in the field and preserved for later counting.
Fecundities were estimated gravimetrically. Ovary wet weight (in grams) was
determined for the preserved samples, then eggs were counted in three subsamples, each of approximately 0.30 grams, taken from anterior, medial, and
posterior sections of the ovary. The arithmetic mean number of eggs per gram
thus obtained was multiplied by the preserved ovary wet weight to determine
fecundity. Relative fecundity (RF) was calculated as:
RF =
Number of eggs
W
where W is wet weight in grams.
This data was arranged from lowest to highest in Table 9. Only arithmetic mean
values with a minimum sample size of 4 individual observations or more were
included.
Table 10 gives estimates of fecundity-total length parameters based on a
geometric mean predictive regression model fitted to logarithmically transformed
(Napierian logarithms) individual observations of number of eggs versus total
length (mm).
ln fecundity = ln D + E ln L
where fecundity is the number of eggs, Į is the intercept, ȕ is the slope, and L is
total length in mm. The equation presented in the tables is Fecundity=eĮLȕ.
Only projects having their derived regression models with slopes and intercepts
significantly different from 0 (p<0.05) were included in this table. Values were
sorted from low to high using the slope parameter (ȕ). The regional benchmarks
were derived using all the data (including multiple years from an individual
waterbody).
3.10 Reproductive Characteristics (Table 11)
Other measures of reproductive condition are summarized in Table 11a for
females and Table 11b for males. Gonads were removed from the walleye and
weighed with an electronic balance that was accurate to at least 1 decimal place.
The fall gonadosomatic index (GSI) of sexually mature fish was calculated as:
GSI =
Gonad Weight
× 100
(Total Weigh t - Gonad Weight)
8
where gonad weight and total weight are in grams.
Fat was gently stripped by hand from the membranes surrounding the digestive
tract, organs and body cavity. Visceral fat was weighed with an electronic
balance that was accurate to 2 decimal places. The visceral fat index (VFI) of
sexually mature fish was calculated as:
VFI =
Visceral Fat Weight
× 100
Total Weight
where visceral fat weight and total weight are in grams.
The index of reproductive effort (R) proposed by Lester et al. (2000) was also
calculated for females and males:
R=
3h
L෱
where h is pre-maturation growth (mm•year-1) and L is asymptotic total length in
mm.
Only arithmetic mean values with a minimum sample size of 3 individual
observations or more were included in these tables. The tables are ordered from
lowest GSI to highest GSI. The regional benchmarks were derived using all the
data (including multiple years from an individual waterbody).
4.0 Analysis and Discussion
4.1 Sexual Dimorphism
The analysis of the 1993 to 2001 FWIN database is unique because most
comparable studies of life history variation have been interspecific, rather than
intraspecific comparisons of population. In this study we have tried to improve
our understanding of the variation in walleye life history by increasing the number
of populations and life history parameters compared to Lester et al. (2000).
Female and male life history parameters were tested for the null hypothesis that
these data were from a normally distributed population using the KolmogorovSmirnov one-sample test (Daniel 1978). Mean population differences between
females and males from normally distributed data were compared using the
paired-sample t test for dependent samples (Zar 1999). For data that were not
normally distributed, the nonparametric Wilcoxon paired-sample test (Daniel
9
1978, Zar 1999) was employed to test for differences between females and
males. The mean difference and the 95% confidence interval for statistically
significant (p<0.05) comparisons between the sexes were calculated. The linear
dependence of variation in a life history parameter between females and males
was tested using simple linear correlation (i.e., we considered the linear
relationship between females and males, but neither is assumed to be
functionally dependent upon the other) (Zar 1999). Statistical comparisons were
performed using STATISTICA data analysis software system (StatSoft 2001).
The mean differences between female and male walleye were statistically
significant (p<0.01) for all life history parameters except relative condition
(p=0.80) (Table 3). Female walleye had lower mortality, higher asymptotic size,
faster early growth, older age at sexual maturity, larger size at sexual maturity,
higher allocation to sexual by-products (i.e., higher gonadosomatic index), and
higher storage of lipid reserves (i.e., higher visceral fat index) compared to males
from the same population. Variation between females and males was statistically
correlated for all parameters (p<0.01).

4.2 Regional Differences
Life history parameters and population characteristics (i.e., geometric mean
walleye relative abundance) for female and male walleye from the northwest,
northeast and south-central region FWIN projects were compared using a oneway analysis of variance (Zar 1999). If a significant (p<0.05) difference in means
was detected a multiple comparison Tukey test was employed to determine
where differences between regions existed (Zar 1999). Statistical comparisons
were performed using STATISTICA data analysis software system (StatSoft
2001). Results are summarized in Table 4.

mean) were significantly different from each other. For all other life history
parameters, except male size-at-50% maturity and male relative condition, there
generally appeared to be no difference between northwest and northeast region
means. However the south-central region means were significantly different from
the other two regions. The mean male size-at-50% maturity for northwest region
walleye populations was significantly different from the other two regions while
the mean male relative condition for northeast region walleye populations was
significantly different from the other two regions.
5.0 Summary
This report demonstrates the utility of gathering sufficient, standard samples to
estimate walleye life history parameters. Females differ significantly from males
and future assessment should recognize that data should be collected and
analyzed separately for the sexes. Walleye populations in the northwest and
northeast region displayed similar life history parameter means and information
from these northern populations may be pooled for future analysis. South-central
population means appeared to be different and should be treated separately.
The regions differed uniquely in only three parameter means: relative
abundance, male relative condition, and male age-at-50% maturity.

Table NW-3a. Annual female walleye mortality (%) for northwest region waterbodies sampled
using the fall walleye index netting standard. “Observed mortality” is a direct
estimate based on age structure of female fish and was calculated from age 5
onwards using Robson and Chapman’s estimator. “Estimated mortality” is an
indirect estimate based on age structure of the population regardless of sex
using the empirical formula: Female mortality = 0.952(Combined sex mortality)
(n=246, R2=0.77, standard error of the estimate=6.493).

Table NW-7a. Empirical female walleye von Bertalanffy growth equation for northwest region waterbodies
sampled using the fall walleye index netting standard. Lf defines the asymptotic or
maximum total length, K is the Brody growth coefficient and defines growth rate towards
the maximum, and to shifts the growth curve along the axis to allow for apparent non-zero
body length at age zero (to=-1). Omega (Z) is early growth and corresponds to the growth
rate near to. h is pre-maturation growth (i.e., growth to 350mm total length for combined
sexes).

1. Pre-maturation growth benchmarks are calculated from all northwest lakes.
NW - 45
Table NW-7b. Empirical male walleye von Bertalanffy growth equation for northwest region waterbodies
maximum total length, K is the Brody growth coefficient and defines growth rate towards the
maximum, and to shifts the growth curve along the axis to allow for apparent non-zero body
length at age zero (to=-1). Omega (Z) is early growth and corresponds to the growth rate
near to. h is pre-maturation growth (i.e., growth to 350mm total length for combined sexes).

SC - 29
Table SC-7b. Empirical male walleye von Bertalanffy growth equation for south-central region
waterbodies sampled using the fall walleye index netting standard. Lf defines the
asymptotic or maximum total length, K is the Brody growth coefficient and defines growth
rate towards the maximum, and to shifts the growth curve along the axis to allow for
apparent non-zero body length at age zero (to=-1). Omega (Z) is early growth and
corresponds to the growth rate near to. h is pre-maturation growth (i.e., growth to 350 mm
total length for combined sexes).
