Stock structure and regional variation in population dynamics of the red throat emperor and other target species of the Queensland Tropical Reef Line Fishery

The Great Barrier Reef Marine Park (GBRMP) is the largest and, arguably, most pristine marine park in the world. Commercial, charter and recreational fishing have occurred on the Great Barrier Reef (GBR) for many decades. Since the late 1980’s, there has been growing concern about the...

Summary

Commercial clam hatcheries require a method of labeling or "tagging" clams so that they can be identified as hatchery reared. This is a requirement of the Queensland Department of Primary Industry, aimed at the prevention of the sale of clams collected illegally from the Great Barrier Reef Marine Park. Methods used for tagging to date have been labor intensive, therefore expensive, and suitable only for sales of small numbers of animals.

This study developed a cheap and relatively easy method of labelling commercially reared clams using a dye which stained the organic matrix of the shells. This dye, Erythrosine B, colours the organic matrix of the shell periphery a bright pink which remains in a band as new shell is laid down. The new shell is not discoloured. The dye meets all the criteria which the project identified as desirable for a chemical tag.

Tactical Research Fund: Adapting to change - minimising uncertainty about the effects of rapidly-changing environmental conditions on the Queensland Coral Reef Fin Fish Fishery

With the severity and intensity of tropical cyclones predicted to increase with global climate change (Webster et al. 2005), the need to understand the effects of these events on fisheries production is paramount. The northern tropical margin of the Australian continent is subject to tropical...

Genetic diversity audit of farm held stocks of Greenlip and Blacklip abalone

Following the AVG virus, the number of broodstock that were available to produce hybrids was drastically reduced. This project was undertaken in order to ascertain the genetic diversity present within farm held broodstock of greenlip and blacklip abalone and to determine the degree of genetic...

Application of ELISA/PCR tests developed in Japan to the detection of a barramundi Picorna-like virus in Australia

The history of BPLV in Australia is one in which mass mortalities have occurred repeatedly among cultured larvae almost completely without warning. There is no published data on where the virus comes from (i.e. its source or origin), or, in the case of stock being transferred interstate, the...
