Feed efficiency, nutrient sensing and feeding stimulation in aquaculture: A review

Ameliorating of feed efficiency always was and will remain the key element of aquaculture in which minimalizing losses during feed intake play an important role. Decreasing feed losses important not only from the economic point of view but also from an environmental standpoint. Feeding stimulants are often used additives in complete aquaculture feeds. Better knowledge of the food-sensing of cultured species is essential in the development of adequate feeding stimulants. The present paper aims to overview the nutrient-sensing of aquatic animals and the use of the wide variety of feeding attractants and stimulants.
