Young fish, often referred to as fry, are the early life stages of fish that hatch from eggs. They are typically very small and vulnerable, relying on their surroundings for food and protection. Fry usually feed on tiny organisms like plankton and algae, which provide the necessary nutrients for growth. As they develop, young fish undergo several stages, including larval and juvenile phases. During these stages, they begin to resemble adult fish and start to explore their environment more actively. This growth process is crucial for their survival, as they learn to find food and avoid predators in their aquatic habitats.
