Development of an algal bloom monitoring buoy for the Australian aquaculture industry: proof of concept

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...

Age and growth of jack mackerel, and the age structure of the jack mackerel purse seine catch

Jack mackerel (Trachurus declivis) is a pelagic species that is found in waters off southern Australia and New Zealand. It is the subject of a major fishery, predominantly off Tasmania, with annual landings in the range of 9,000 - 42,000 tonnes. The fishery commenced in the mid 1980s and uses purse...

Assessment of inshore habitats around Tasmania for life history stages of commercial finfish species

In Tasmania, there is a paucity of information on the life-history, population parameters and habitat requirements of fish associated with inshore soft-sediment habitats, particularly seagrasses. Clearly, such information is needed before stock assessment models can be developed, recruitment...

Radiometric aging of sharks

Determining the age of sharks is difficult. A reliable independent method of validating age estimates is needed, apart from relying on tag return data. The success of radiometric analysis for bony fish overseas and in Australia suggested that it would be worth trying the method on sharks. Four...
