Population Sizes

A population of lake whitefish (Coregonus clupeaformis) in the waters off eastern Manitoulin Island in Lake Huron was sampled from 1950 to 1982 by an experimental pound net in the outer basin of South Bay. Year-class strength increased markedly from 1947 to 1977; the increase began with the decline of the 1943 year-class. The fork length attained by age 1–3 fish decreased during the study, but no trend was apparent for older fish. Natural mortality of year-classes varied considerably, and was probably related to the abundance of lamprey. The annual exploitation rate increased from 1 to 37% between 1960 and 1977. Year-class strength was not correlated with the thermal regime during spawning and hatching. Recruitment was a function of parental stock size, and there was evidence that survival from the egg to juvenile stage was inversely correlated with parental stock size. Instantaneous growth rates (G) during the 2nd year of growth were inversely related to year-class strength. Growth (G) in the 1st year was positively correlated with estimated surface water temperatures. The sizes attained by ages 2 and 3 were inversely related to total population abundance. Catchability coefficients in 144-mm-mesh gill nets were inversely related to estimated population sizes. An intrinsic mechanism of population regulation is proposed whereby recruitment is a function of parental stock size, juvenile survival is inversely related to stock size, and growth is inversely correlated with population abundance.

The Relationship

We found no significant differences in slope or intercept for the regression of loge fecundity on loge fork length among samples of whitefish from four lakes near Yellowknife in the Northwest Territories. The equation describing the relationship between fecundity and fork length for these populations was:[Formula: see text]Five other populations for which length–fecundity relationships could be calculated had length exponents ranging from 3.20 to 4.38, suggesting a nonlinear relationship between weight and fecundity. Six of the nine populations as well as four others for which limited data were available all had similar relative fecundities. Fish from Buck Lake in Alberta and from Lake Erie had high relative fecundities while fish from Great Slave Lake had low relative fecundity.

AbstractDNA barcoding is a useful tool for both species identification and discovery, but the latter requires denser sampling than typically used in barcode studies. Lake Whitefish (Coregonus clupeaformis) is a valuable species, fished traditionally, commercially, and recreationally in Lake Huron. Based on the natural geographic and bathymetric separation of the three major basins in Lake Huron, the potential separation of Lake Whitefish within these basins, and the variation among life history (early and late spawning), we predicted that Lake Huron might harbour cryptic lineages of Lake Whitefish at the basin level. To test this prediction, DNA barcodes of the mitochondrial 5’ cytochrome c oxidase subunit I (COI) gene sequences were recovered from spawning phase Lake Whitefish (n = 5 per site), which were collected from sites (n = 28) around Lake Huron during Fall 2012. These sequences, combined with other publically available DNA barcodes from the Barcode of Life Data System (BOLD), revealed twelve unique haplotypes across North America, with seven unique to Lake Huron. The dominant haplotype was found throughout Lake Huron and east to the St. Lawrence River. No deep divergences were revealed. This comprehensive lake-wide sampling effort offers a new perspective on C. clupeaformis, and can provide insight for environmental assessments and fisheries management.

Growth And Reproduction

In Lac la Ronge the lake whitefish (Coregonus clupeaformis (Mitchill)) spawned from late October until the middle of November at ages of 8 years and over. The growing season lasted from late May to early October and young fish grew faster than older ones and tended to have a longer growing season. Ages for 1604 fish taken during 4 years showed that they grew to a fork length of about 16 inches in 10 years, the rate being slower than for lake whitefish in other large lakes in North America. The length-weight relationships were linear: for the open lake, log W = 3.48 log L – 3.93, and for Hunter Bay, log W = 3.26 log L – 3.66. The males matured a little earlier than females and their life span was somewhat shorter. The sex ratio was approximately 1:1.

Historical and contemporary data on lake whitefish (Coregonus clupeaformis) from the Ontario waters of Lake Huron were examined for evidence of stocks with the objective of defining population boundaries. We delineated the spatial distribution of five stocks from tag–recapture data and the general location of six additional stocks on the basis of population parameters such as growth rate, age structure, and abundance trends.Samples of fish collected (summer and fall) from 5 of the 11 potential stocks were evaluated on the basis of 11 morphometric and 7 meristic characters. We also examined osseometric features such as shape of scales and otoliths, and electrophoretic characteristics at 32 loci associated with 12 enzyme systems.The summer and fall samples for each group were generally not significantly different. For the phenotypes examined electrophoretically, each stock was in Hardy–Weinberg equilibrium; 12 of the 32 loci considered were polymorphic and 4 of the 10 possible genetic distances differed significantly from zero.The Inner Basin stock was distinctly different from all other stocks. The Blind River stock was also found to be different by osseometrics, but not by morphometrics or electrophoresis. Osseometrics separated the stocks by basin of origin. Two stocks, Outer Basin and Burnt Island, appeared to be the most similar and could be separated from each other only on the basis of growth rate and tagging data. These two stocks are adjacent to each other in the main basin of Lake Huron, along the south shore of Manitoulin Island.Whitefish stocks of Lake Huron represent groups of fish that differ phenotypically and genotypically in varying degrees, are spatially separated, and behave as cohesive units. We conclude that they should be regarded as functional units for management purposes.Key words: lake whitefish, Coregonus clupeaformis, Lake Huron, stocks, tag–recapture data, population structure, morphometrics, meristics, osseometrics, scale and otolith shape, starch gel electrophoresis, biochemical genetic variation

Surplus Production Model

The logistic surplus production model is applied to lake whitefish (Coregonus clupeaformis) yield and effort data from Lake Superior, Lake Michigan, and Lake Huron. The fitted models indicate that the whitefish populations in most areas of the lakes have been overexploited, and that in these areas yield was below the maximum sustainable yield before sea lamprey (Petromyzon marinus) predation took its toll. In some areas of Lake Superior the whitefish populations are not overexploited. The sea lamprey is the apparent cause of the drastic decrease in the whitefish population that occurred in northern Lake Michigan during the 1950’s.

Creel Census

The smallmouth bass (Micropterus dolomieui) population of South Bay, Lake Huron and the sport fishery imposed on it have been studied by means of marking and creel census carried out during the years 1947 to 1952 inclusive. Population estimates of legal-sized bass (over 10 inches–fork length), based on the recovery of marked fish, show a decrease from 5,900 fish in 1947 to 2,900 in 1949 with an increase again to 5,700 in 1952. The number of bass caught per 100 rod-hours in these years was 89, 51 and 87, respectively. The recovery of the population from its low in 1949 was due solely to the 1947 year-class which dominated the fishery in 1950, 1951 and 1952, contributing 34%, 71% and 67%, respectively, of the anglers' catch in these years. Analysis of scale samples of the anglers' catch shows considerable variation in year-class strength. In contrast to the 3,500 fish contributed to the anglers' creel by the 1947 year-class, the 1945 year-class contributed only 400 fish.South Bay bass enter the sport fishery in small numbers at age III and 70% of the anglers' catch consisted of age-III to age-V fish. Sixty per cent of the legal-sized population of bass present in South Bay in one year are taken by anglers in the succeeding 4–5 years at the present exploitation.A large percentage of the bass population is located in the Inner Basin of South Bay where they are dispersed in varying concentrations along the shoreline. During the five-year study 3,331 bass were tagged and, although the loss of tags was high, 692 were recaptured by trap nets in the same season they were released. Eighty-five per cent of these were taken within two miles of their release point. Of 60 bass recaptured a year after tagging, 43 (72%) were taken within two miles of their release point. Only five per cent of all recorded recaptures were caught over five miles from their release point. Larger bass tended to range farther than small bass.
