Introduction:
This unit is based on production and husbandry of Australian aquaculture. The information provided will give a comprehensive understanding of the methods for measuring and monitoring water quality in aquaculture production systems. Fish are dependent on and perform all of their bodily functions in water, so it is important to be familiar with normal water quality parameters. This guide allows one to learn basic health assessment diagnostic procedures as well as water quality testing skills.

Safety:
To ensure safe and humane handling, sterile equipment as well as clean work benches should be used. To reduce the spread of disease, clean lab coats, sterile gloves and safety goggles should be worn at all times.

Skills:
Normal fish behaviour, as well as signs and symptoms of disease
Understanding the need and benefits of anaesthetics in aquaculture
Assessing the main water quality parameters
Understanding how internal and external examinations of fish are performed
Recognising some adaptations in fish
