{"Image DocumentName": "Perch Facts", "Image ImageDescription": "Yellow perch (Perca flavescens) is a species of perch found in the U.S. and Canada in both fresh and salt water lakes primarily. Recognized by its dark vertical stripes and gold or yellow body color. Size: adults are usually between 4-10 inches ( cm) in length. Lifespan: up to 11 years Diet: Adult perch dine primarily on immature insects, larger invertebrates, (crayfish, etc.) and the eggs and young of other fish, which they take both from open water and from the bottom. Spawning occurs at the end of April or beginning of May, depositing 10,000 to 40,000 eggs upon weeds, or the branches of trees or shrubs that have become immersed in the water. After fertilization the eggs hatch in 11 to 27 days depending on temperature and other weather conditions.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
