An appropriate diet for fish consists of essential nutrients (proteins, lipids, carbohydrates including fiber, vitamins, and minerals), in a suitable formulation that is often similar to the wild diet, and adapted to the life stage and conditions under which the animal is managed. Most studies on fish nutrition have focused on species that are routinely cultured for food (e.g. salmon, trout, tilapia, and catfish), where the goal is often rapid growth and efficient production. Little information exists on the nutrient requirements of fish kept in zoos and aquariums and in the home, where the goal is to optimize health to enhance longevity and reproductive success. In the absence of information on nutrient requirements, understanding the wild diet and foraging ecology, metabolism and energetics, and anatomy can help in choosing appropriate items to feed.
