Book Description
The success of the yellow perch Perca flavescens aquaculture industry depends largely on increasing growth efficiency to reduce production costs, and increasing fingerling availability for year-round production. Two characteristics of yellow perch biology pose challenges toward these goals. 1) Yellow perch exhibit sexually dimorphic growth, detected concurrently as the fish enter puberty, with many slower-growing males that may never achieve market size. These growth differences between genders also promote a situation in which cannibalism can quickly deplete a perch population reared under intensive conditions. 2) Yellow perch spawn once a year in the spring, and most producers are limited to a production schedule centered on this event. Two sets of studies were conducted to evaluate culture methods for the inhibiting maturation for promotion of somatic growth, and evaluate the practice of 'cold-banking' for off-season fingerling availability. Four combinations of constant and natural photothermal regimes were used to impose environmental conditions on juvenile fish that inhibited maturation and promoted somatic growth. Immature perch were expected to demonstrate reduced dimorphic growth pattern and overall growth enhancement. Results indicate that a) constant temperature is the strongest promoter of overall growth regardless of photoperiod; b) constant photoperiod also promotes overall growth regardless of temperature; c) natural (decreasing) photoperiod initiates maturation in yellow perch regardless of temperature; d) natural temperature is required for late maturational processes; e) constant temperature and constant photoperiod together confer the best overall growth performance, fully inhibit maturation in both genders, and suppress a sexually dimorphic growth pattern up to 53g average weight. Two studies were conducted evaluating the growth of cold-banked fish and costs associated with commercial application of this culture technique. Perch banked at 10 C on.

Book Description
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.

Abstract: Yellow perch (Perca flavescens) is a highly valued food fish that is receiving increasing attention as an aquaculture species. Demand for yellow perch fillets is exceeding commercial catch as the species becomes increasingly popular and traditional fish supplies are lost. This loss of supply provides an opportunity for commercial culture of yellow perch. This study addresses the need for formulated dry diets specifically for early stage yellow perch, since the process of weaning fish to dry diets is the most critical stage of culture and current diets have not equaled the performance of live food. The first experiment focused on fish initially reared in ponds that were weaned to dry diets in tanks. Nine diets were tested, alone or in combination with Artemia nauplii or attractant coatings, for their effects on fish growth and digestive enzyme activity. Fish fed attractant-coated diets exhibited significantly larger length gains (p

Book Description
This extensive work focuses on an important group of temperate freshwater fish, approaching the topic from the perspectives of both biology and aquaculture. It compiles the latest research on fish belonging to the Percidae family and describes in detail all biological aspects relevant to the culture of different species, including ecology, reproductive physiology, feeding and nutrition, genetics, immunology, stress physiology and behavior. It also considers commercial fish production and fish farming topics, such as protocols for induction of gonad maturation, spawning, incubation and larval rearing. Expert contributors not only provide a critical peer review of scientific literature but also original research data, and identify effective practical techniques. The book features chapters on systematics, ecology and evolution, on development, metabolism and husbandry of early life stages and on growth, metabolism, behavior and husbandry of juvenile and grow-out stages. Furthermore, the authors consider genetic improvement and domestication, as well as diseases and health management, crucial to the readers' understanding of these fish and how they can be cultured. Both researchers of percid fish biology and aquaculture professionals who are considering intensive and pond culture of percid fishes will value this timely and comprehensive handbook.)
