Young Perch (1981)

This documentary explores the life cycle of the perch, tracing its development from the spawning process to maturity. After a female deposits her eggs in the branches of a lake, she guards them from predators until they hatch into fry, which initially rely on a yolk sac for sustenance before transitioning to a diet of plankton. The film highlights the high mortality rate of young fish due to various predators and environmental factors, emphasizing their need to consume significant amounts of food to grow quickly. As they mature, the perch develop their characteristic stripes and fins, learning to navigate the dangers of the lake—including larger predatory fish like pike—until they reach adulthood after several years.
