Factors that influence Yellow Perch survival and reproduction in Iowa’s community ponds

Abstract

Over the last century, there has been a shift in the United States population towards a more urbanized environment, with the vast majority of Americans (~80%) now living in urban areas. This has caused an alteration in recreational interests, as participation rates associated with traditionally rural activities (i.e., recreational angling), have steadily declined. Increased urban development and decreased angler participation have persuaded fishery managers that efforts to recruit and retain community (i.e., urban) anglers was necessary in contemporary fisheries management. However, distinct biotic and abiotic characteristics and diverse angler preferences and motivations in community fisheries make traditional fisheries management approaches frequently inadequate to meet management goals. Although introductions of novel species in community fisheries are often encouraged to meet diverse angler desires, investigations of their populations to assess viability in this environment are limited. For instance, Yellow Perch Perca flavescens is a popular sport and food fish across its range and investigations into its survival and reproduction are extensive. However, this research has been predominately conducted on natural lakes, rivers, and reservoirs, and little is known about populations in community fisheries, although this information is essential for effective management. Therefore, the overarching goal of the research was to assess whether Yellow Perch is a viable stocking option in central Iowa's community ponds. The specific objectives of this research project included: (1) evaluate factors that influence Yellow Perch exploitation and survival in central Iowa's community ponds, (2) evaluate factors that influence Yellow Perch reproduction and recruitment in central Iowa's community ponds, and (3) to investigate the importance of coarse woody habitat complexity on Yellow Perch skein deposition and survival.
