Preparation of a set of guidelines on the procedures necessary to carry out baseline studies at any Australian coastal site

The discharge of ballast water from one port into another is not a recent phenomena, although its importance as a dispersal mechanism for marine species has only been fully realized in the last decade with increasing volumes of ballast water being discharged and more studies being carried out on the...

Prawn farm effluent: origin, composition and treatment

Prawn farming is an expanding, high-value primary industry in coastal areas of Australia. Currently there are approximately 500 ha of farm ponds. The majority of prawn farms are in Queensland, but there are also farms in NSW, NT and WA with plans for expansion of the industry in all these states....

Immuno-staining of a ciliate protozoan causing significant mortalilty of farmed tuna: the development of a rapid identification technique which will enable improved farm management practices to be implemented to minimise fish mortality

An immunofluorescent staining technique for the rapid detection of the ciliate protozoan Uronema sp. was developed during 1995 and 1996. The initial test was developed using seven cultures of Uronema sp. from various sources which were identified as Uronema nigricans by microscopical and...

Identification of environmental factors, with particular reference to acid sulfate soil runoff, causing production losses in Sydney rock oysters

The study has confirmed that estuarine acidification, associated with drainage of acid sulfate soils, reduces growth rates and survival in Sydney rock oysters leading to significant production losses. The work has also demonstrated that acidification is not a factor in outbreaks of QX disease. The...

Need

Commercial fishing is one of the most energy intensive food production methods today and the Australian industry consumes approximately 205 million litres of diesel fuel per annum. The fishing industry needs to radically improve the energy efficiency of its operations primarily due to the rising cost of fuel and its effect on operating margins. The recent rapid increase in cost of diesel has reduced margins to such a low level that it is rapidly becoming uneconomical for operators to continue to trade. This has significant flow-on effects down the whole production-processing-retail chain.

In addition there is a global need to reduce the emissions of oxides of nitrogen (NOx) and carbon dioxide (CO2) from fossil fuel combustion. The global fisheries industries emit annually more than 130 million tonnes of CO2 into the atmosphere.

Trawling is a very energy intensive fishing method, for example Australian prawn trawlers incur fuel costs of approximately 35% of total production costs. The use of alternative auxiliary powering systems, such as sails, has the potential to radically reduce fuel consumption by a combination of providing supplementary propulsive thrust and reducing vessel motions and consequent drag.

Several fishers in Australia have installed sails onto their vessels with the aim of reducing fuel consumption, but no investigations have been conducted to ascertain the effect the auxiliary systems actually have on fuel consumption, performance and costs. The results from an energy audit on such a vessel would provide valuable information to other fishers on the benefits, or otherwise, of fitting such a system to their vessel.

The need for this work was highlighted by the results from recent FRDC sponsored energy audits of fishing vessels. The 1st International Symposium on Energy Efficiency in Fishing was held in May 2010 and clearly emphasised the need for continuing RD&E in this area.

Objectives

1. Energy audit (level 2) on prawn trawler fitted with auxiliary sail system.
2. Collect data on effect of use of sail system on fuel consumption in varying environmental conditions.
3. Analyse energy audit data to determine effect of sail system on fuel consumption.
4. Disseminate information on effect of sail auxiliary power system to owners and operators of fishing vessels.

ASBTIA: Optimising the use of praziquantel to manage blood fluke infections in commercially ranched SBT

This report provides a summary of work performed to develop methods to quantify Cardicola forsteri and Cardicola orientalis infections in Southern Bluefin Tuna (SBT) and an in vitro study to determine the efficacy of praziquantel as a treatment for C. forsteri infections. The project was also...
