This book was released on 2004 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Different approaches were used to characterize, assess, test and model the fish-habitat interactions of yellow perch in Long Point Bay. Chapter 1 describes the methodologies for explicitly characterizing spatial and temporal habitat through mapping and modelling. Chapter 2 connects habitat and ontogenetic niche shifts in perch life history, with the aim of determining suitable habitat availability for the Long Point Bay perch population. Habitat suitability indices and models were used to map and identify the areas of suitable habitat, including thermal habitat. Chapter 3 compares a known distribution of yellow perch larvae with HSI predictions of habitat suitability as a validation exercise. Abundance and size distributions from the survey were compared to thermal and HSI predictions of suitable habitat to test for correspondence. The relationship between food availability and habitat characteristics, especially vegetation, were also tested. A model was developed in Chapter 4 that concentrated on the first year of life and the effect of consecutive constraints on early life stages with different habitat requirements. The purpose of the model was to compare the potential growth and survival of consecutive life stages in a spatially explicit manner when different habitat-based rules are imposed. The results highlight the importance of life history theory and knowledge of mechanisms used in habitat selection for determining limits to fish production.

This book was released on 2005 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This study evaluates the life history responses of yellow perch to mass removal and the potential for population recovery. We removed approximately 94% of a perch population from Nepawin Lake, a 35 hectare oligotrophic lake in Algonquin Provincial Park, Ontario, as part of a study designed to enhance the recruitment success of brook trout. Several response variables were examined both before and after mass removal: (1) condition, which includes growth, diet and overall condition responses, and (2) reproduction, which includes size at maturity and fecundity. We examine the question of whether compensatory life history responses in the yellow perch will overcome brook trout predation leading to a reestablishment of a high density perch population. Results showed that prior to the manipulation, perch exhibited a narrow size distribution, high dietary overlap, and low condition, typifying a stunted population. After mass removal, the perch population remained in a narrow size distribution, exhibited decreased growth rates for older age classes, showed increased mean condition and increased consumption of zooplankton in all size classes. Perch also exhibited increased size at maturity and decreased fecundity immediately following the mass removal. A time lag is expected before compensatory recruitment is possible in the population, but it is likely that the perch will recover from the mass removal because of strong age 0+ and 1+ cohorts. However, stunting and bottlenecking may still occur in the population. Continued monitoring and management is necessary to observe further changes to the perch population dynamics in Nepawin Lake." --

This book was released on 2000 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Yellow perch populations in Lake Erie exhibit large yearly fluctuations in year class strength (YCS), with most years showing relatively poor recruitment. For percids, no statistically significant relationship between stock and recruitment has been found. Most research has focussed on various environmental factors to explain the variability in YCS. Of the studies reviewed in the first chapter, variations in YCS could not be explained by variation in any single environmental factor. The second chapter revisited the theoretical equation that spawning stock size is related to recruitment. Yearly variation in the number of mature females in the spawning stock may explain the variability in the YCS of perch. We found that the proportion of fish at age varied annually from 1978-1990, suggesting that intermittent reproduction exists for Lake Erie yellow perch. The third chapter evaluated through a model whether variation in the proportion mature as well as interannual variations in age distributions, size and the associated size-related fecundity could explain the variability in YCS of the yellow perch populations. Variation in the proportion mature could explain a large proportion of the observed YCS, however we could not accurately predict recruitment from the variations in the life history parameters included in the model.
