Determination of the disease status of Western Australian commercial prawn stocks

There is little published information on the disease status of the prawns on the north-west shelf, yet these prawns (Fenneropenaeus merguiensis, Metapenaeus endeavouri, Penaeus esculentus and Melicertus latisulcatus) form the basis of a commercial fishery worth in excess of A$42 million in...

Summary

Infection by marine Vlbrlo bacteria is still considered to be
the major opportunistic cause of mass mortalities of pearl
oysters (Pinctada maxima} on farm lease sites in the north
west of Western Australia. Vibriosis of P. maxima was found
to occur following some form of stressful husbandry practice
as similar mortality outbreaks were never apparent in natural
populations of pearl oysters throughout this investigation.
Potentially harmful Vlbrlo species were found to be associated
with pearl oysters in the Broome region throughout the year;
therefore vibriosis could occur at any time to oysters
subjected to excessive stress.

Aquatic Animal Health Subprogram: development of a national translocation policy using abalone and prawns as templates for other aquatic species

The use of scientifically based hazard identification, risk analysis and risk management is fundamental to managing unwanted effects. Hazards, such as quarantine incursions, will continue to occur despite the use of risk assessment methodologies but the frequency and severity of their...

To further development of aquaculture of marron by testing a specially designed pond sited in the most climatically favourable location in Western Australia

Extensive research has been conducted on the growth cycle of marron, a type of freshwater crayfish. in Western Australia. The research suggests that the most favorable area for marron is near Cape Leeuwin. People interested in setting up an aquaculture facility for marron are advised to seek a pond...
