Freshwater Environments

Daily Eating Habits

Crayfish eat mostly at night. They are more active after sunset and search for food then. During the day, they hide and rest. Young crayfish eat more often because they grow fast. Adult crayfish eat less but still need regular meals. They prefer small, frequent feedings instead of large meals.

Seasonal Variations

Food availability also changes with seasons. They adjust their diet based on what is around them. This helps them survive through different times of the year.
