Book excerpt: Variability in annual recruitment for many fishes is correlated with survival during the larval phase. Yellow perch in Lake Michigan have experienced sustained recruitment failure since 1990 and this has been blamed on low larval survival. Direct examination of factors important to larval yellow perch survival in Lake Michigan is complicated by the large size of the lake (52,000 km2) and the short length of the pelagic larval period (30-40 days). Individual-based modeling is a valuable indirect method for assessing the importance of multiple factors to larval survival. I used an individual-based modeling approach combined with field data collection to test four hypotheses regarding factors limiting survival of larval yellow perch in Lake Michigan. I tested whether larval survival is limited by prey community composition, size-selective predation, advection of larvae into offshore habitat or an interaction of these factors. I sampled larval and zooplankton abundance in Lake Michigan along a transect from 1 - 32 km from shore in 2000 and 2001. I conducted laboratory experiments to quantify larval vulnerability to predation by three typical predators as a function of both predator and prey size. I also conducted laboratory experiments to quantify larval selectivity for different zooplankton prey as a function of larval size and prey community composition. I used the results of these experiments to develop an individual-based model specifically to describe growth and survival of larval yellow perch. Field data suggest that larval yellow perch are being transported from the nearshore to the offshore zone of Lake Michigan, but the timing of this transport varies between years. Model simulations in which the offshore prey community and the timing of larval advection were both varied suggested that larval survival will be highest in years when advection occurs within two weeks of peak hatch, allowing larvae to exploit offshore prey resources early during ontogeny. The.

This book was released on 2013 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the effects of turbidity on visually foraging fish species can be difficult due to the dynamic nature of sediment plumes and algal blooms in productive aquatic systems. In this dissertation, I examined the effects of turbidity type, timing and intensity on age-0 yellow perch (Perca flavescens). To accomplish this, I used ArcGIS and generalized additive models (GAMs), individual based models (IBMs) and the Soil and Water Assessment Tool (SWAT). The initial study utilized ArcGIS and GAMs to determine the relationship between turbidity and size and abundance in August of age-0 yellow perch. The GAMs presented in this dissertation show that water clarity (in this case used as a surrogate for turbidity) is an important environmental factor in determining the length and abundances of age-0 yellow perch in western Lake Erie. The results suggest that the influence of water clarity produces a distinct separation of areas of higher growth potential and areas of higher abundances in the western basin. While this division may be attributable to a number of mechanisms, including size dependent predation risk, foraging ability, and density dependent growth, the effects of water clarity, and in particular the negative effects of algal blooms, on foraging ability are of particular interest in Lake Erie. For the second step in this research I used laboratory derived feeding rates in a range of turbidity types and intensities to inform IBMs that varied the timing, type and intensity of turbidity to determine the effects of changes to a systems turbidity regime on growth and starvation mortality. The results of the model suggest that the timing and persistence of sediment plumes and algal blooms can drastically alter the growth potential and starvation mortality of a yellow perch cohort. The timing of sediment plumes in particular can have significant consequences to the growth, and ultimate success of a yellow perch population. High sediment turbidity early in the season, prior to the ontogenetic shift, can be potentially beneficial to fish growth. However, if high sediment turbidity conditions persist, they can slow growth and increase the starvation mortality of juvenile fish. In contrast, algal blooms, no matter when during the season they occur. In the final study, I used SWAT and IBM models to link watershed level changes in land use and climate to potential changes in age-0 yellow perch growth in the Maumee Bay, Lake Erie. Changes in land-use, either through increased urbanization, or changing agricultural practices, primarily affect fish growth through the alteration in the timing and intensity of sediment plumes. However, it may be that, at least in the Maumee River watershed, the negative effects have reach a plateau of sorts, with significant reductions in fish growth requiring changes to the watershed that are unlikely in the near future due to economic and infrastructure restrictions. Climate change, on the other hand, could potentially compound the effects of current land use practices through the promotion of algal blooms due to increased water temperatures, thus further reducing fish growth. The results of these three studies show that the effects of turbidty on age-0 yellow perch are dynamic, and can vary significantly depending on a number of different factors. The results of this research help to illuminate these complex interactions, and provide a warning about potential consequences due to anthropogenic alterations of an aquatic system's turbidity regime.

This book was released on 2021-11-21 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Walleye, one of the most sought-after species of freshwater sport fishes in North America, has demonstrated appreciable declines in their numbers from their original populations since the beginning of the 20th century. Similarly, Yellow Perch, once the most commonly caught sport fish and an important commercial species in North America, have also shown declines. Compiling up-to-date information on the biology and management of Walleye, Sauger, and Yellow Perch, including research on systematics, genetics, physiology, ecology, movement, population dynamics, culture, recent case histories, and management practices, will be of interest to managers, researchers, and students who deal with these important species, particularly in light of habitat alterations, population shifts, and other biotic and abiotic factors related to a changing climate.

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.
