It is desirable for any primary producer to understand the health and welfare of their stock. This will ultimately enable optimal production and return on investment. The challenge in any aquaculture system is ‘observing’ the physiological and behavioural responses associated with environment,...
The salmon farming industry has significantly expanded in South-eastern Tasmanian both in production and in number and location of farms. Along with this expansion has been an increasing concern from the general community about the effects of salmon farms on the environment. This includes a reported...
A prototype of an automatic algal monitoring buoy was developed for unattended operation in shellfish and finfish farm waters. The instrument employs novel antifouling and self-calibration strategies (subject to a provisional patent ) based on a battery-powered actuator extending into the seawater...
The 2012 Tasmanian biotoxin event represents a paradigm shift for seafood risk management in Tasmania and Australia as a whole. The causative dinoflagellates are extremely difficult to identify by routine plankton monitoring, and are toxic at very low cell concentrations (50-100 cells/L). Sampling...
Tagging is an important tool for estimating key fisheries parameters such as fishing mortality, natural mortality and growth. This project identified the need for future tagging projects to undertake preliminary studies to determine the impact of tagging on both growth and survival, and we developed...
