Pathogenic Vibrio parahaemolyticus in Australian oysters

This project was designed to produce a “snapshot” of the prevalence of the bacterium Vibrio parahaemolyticus in Australian oysters during March and April of 2002. V. parahaemolyticus occurs in two main forms: pathogenic and non-pathogenic. In the past 3 years there have been several...

Understanding recruitment collapse of juvenile abalone in the Eastern Zone Abalone fishery – development of pre-recruitment monitoring, simulation of recruitment variation and predicting the impact of climate variation

Over the past three decades the Tasmanian Eastern Zone Abalone Fishery has experienced several fluctuations in catch and catch rates of Blacklip Abalone as well as environmental perturbations, which may be affecting productivity. The capacity to measure inter-annual variation in Blacklip Abalone...

Objectives

1. Estimate abundance & production of krill (especially Nyctiphanes australis) in an area of sth-east Tas coastal waters.
2. Study growth & moulting of N. australis to provide data for production estimates.
3. Identify the major predators & estimate their consumption

Summary

This final report on the project describes data on stomach contents of major fish predators of the euphausiid Nyctiphanes australis.

The study has concluded that: size and stock of krill and its production can be calculated with some degree of confidence; major predators of adult krill can be identified though the greatest mortality, which occurs in the larval stages, is probably due to carnivorous zooplankters; and swarming by krill is of extreme importance in increasing the attraction of krill as food.
