General course objectives
The overall aim of the course is to introduce students to the field of fish nutrition and bioenergetics, and its application in aquaculture and wild populations of fishes.
The course covers fundamental concepts in fish nutrition and bioenergetics. There is a particular focus on the digestive system, macronutrients, energetics and metabolism. Nutritional requirements and essential nutrients are covered from a feed manufacture perspective, including considerations in the selection of raw materials and substitution. The course covers dietary preferences in wild populations, foraging strategies in wild fish, influence of feed type on gastric evacuation, adaptations to variations in prey availability, using static and dynamic energy budget models, estimating feed intake in wild populations. The course will cover the anatomy of the gastrointestinal system, digestive processes and feed intake in fish. The course covers the biochemistry, physiological roles and requirements of protein and amino acids, lipid and carbohydrate and digestible energy, as well as nitrogenous excretion, cost of feeding, and the partitioning of net energy intake.
