The topic covers the biology and culture of live food organisms including algae, rotifers, cladocerans, copepods, Artemia that are used for aquaculture. The theory and practice of nutritional requirements (protein, lipid, carbohydrate, vitamins and minerals), aquaculture feed formulation and manufacture for a variety of aquatic species will be included. This topic teaches the impacts of the biological processes of aquatic organisms (photosynthesis, respiration, excretion of metabolites and biota/substratum interaction) upon water quality. It also covers technologies and approaches (aeration, buffering) to minimise the deleterious effects of these processes in various aquaculture systems. The topic extends to pond management through nutrient fertilisation and liming. Completion of this topic will enable students to understand the technology of green water culture, feed preparation, and feeding practices and water quality management in the culture of a variety of fish, mollusc and crustacean species.
