In-situ electrochemical generation of caustic and oxygen from sewage for emission control in sewers. This project aims to deliver an innovative technology that controls the emission of notorious compounds from sewer networks using chemicals directly produced from sewage, with electricity being the input. Compared to existing methods, this technology provides a much safer and more environmentally friendly solution, at less than 50 per cent of the cost.

New methods include measurement of adenylates and ATPase in fish tissue samples. 2. To evaluate methods of sampling fish or fish tissues from pens which will reduce stress and improve the probability of recovery of sampled fish which are returned to the pens.

Pilchard Mortality Events In Australia And Related World Events

Summary
The lack of a consolidated report on the 1995 pilchard mortality event hampered the Joint Pilchard Scientific Working Group in its investigation of the 1998 mortality event. It remains uncertain that the response to the 1998 mortality was efficient and it poses the risk that should another event occur in the future, it too will be met with a poorly-coordinated response. Such a response may not yield adequate data or appropriate data for researchers and fisheries managers around Australia. There ....The lack of a consolidated report on the 1995 pilchard mortality event hampered the Joint Pilchard Scientific Working Group in its investigation of the 1998 mortality event. It remains uncertain that the response to the 1998 mortality was efficient and it poses the risk that should another event occur in the future, it too will be met with a poorly-coordinated response. Such a response may not yield adequate data or appropriate data for researchers and fisheries managers around Australia. There is also a risk that scientific investigations may be duplicated, resulting in an inefficient use of industry and public resources.
The lack of a detailed analysis of the events of both 1995 and 1998 and of similar events in other parts of the world compound the difficulties involved in an evaluation of the implications of the mortalities to commercial fisheries and other species which depend wholly or in part on access to pilchards, eg sea lions and penguins. Objectives: 1. Prepare a comprehensive report of pilchard mortality events in Australian waters prior to 1995 and in waters world wide to the present time 2. Provide a summary of the 1995 pilchard mortality event 3. Prepare a comprehensive and competent technical report on the pilchard mortality event in 1998 4. Describe and evaluate the coordinating and managing approaches taken in 1995 and 1998 pilchard mortality events 5. Assess the implications of the pilchard mortality events 6. Evaluate the conclusions which can be drawn from various hypothese as to the cause, origin, trigger and epizootiology of the events 7. Assess options for managing future pilchard mortality events Read moreRead less

Rapid CYBERNOSE ® detection of illicit drugs and precursor chemicals. This project aims to develop a novel biosensor prototype based on CYBERNOSE® technology to rapidly identify volatile traces of illicit drugs and precursor chemicals in concealed environments. The CYBERNOSE® technology employs sensors using the highly sophisticated and sensitive olfactory receptors of microscopic nematode worms linked to an optoelectronic detector. The need for rapid, non-contact screening devices to detect and identify illicit drugs and precursors entering Australia has never been greater. Law enforcement agencies should directly benefit from the capability to more rapidly screen people and cargo, improving efficiency of illicit drug detection and protection of our borders.Read moreRead less
Identification Of A Y-chromosome Marker In Atlantic Salmon (extension To FRDC 95/80)

Summary
Genetic variation The results we have obtained in the current project are encouraging for SALTAS, as they confirm the earlier allozyme results of little loss of genetic variation. However, the results are also suggestive of a potential long term trend in loss of genetic variation. A sample collected and analysed in January 1997 (1993 year-class parents) would provide evidence to substantiate this trend or indicate whether the current results were a sampling artifact. The analysis of a 1997 ....Genetic variation The results we have obtained in the current project are encouraging for SALTAS, as they confirm the earlier allozyme results of little loss of genetic variation. However, the results are also suggestive of a potential long term trend in loss of genetic variation. A sample collected and analysed in January 1997 (1993 year-class parents) would provide evidence to substantiate this trend or indicate whether the current results were a sampling artifact. The analysis of a 1997 sample would be the second of a proposed regular 4 to 5 year assessment of the status of the Tasmanian stock, and would help to describe the nature and speed of any long term trends.
SALTAS, as the principal Atlantic salmon hatchery in Australia, has a long term requirement to maintain industry and investor confidence in their product, and the ability to confirm the reliability of its breeding practices is important for the sustainability of the industry.
Loss of genetic variation in a cultured population will provide an early indicator of potential inbreeding, which could have grave consequences as deleterious recessive genes are exposed and stocks lose vigour dependent on genetic variance. Any loss of genetic variation in Tasmanian Atlantic salmon could be difficult or impossible to recover due to the restrictions on importation of new broodstock.
Y-chromosome marker A number of molecular genetic techniques for trait or marker screening have been developed since the original proposal was submitted. We propose to apply some of these new techniques to the screening of Atlantic salmon DNA for a potential Y-chromosome marker. These approaches will greatly increase our chances of finding such a marker.
The new techniques we propose include: Representational Difference Analysis (RDA); PCR-Select cDNA Subtraction Technique; the application of other modified subtractive hybridization and differential display techniques that have proved useful in other species; AFLP (amplified fragment polymorphism) technique; and the application of a number of commercial RAPD (random amplified polymorphic DNA) primers.
We have also established contact, and will collaborate during the proposed project extension, with workers who have a Y-chromosome marker for brook trout and arctic char, and other workers in this field working with other teleosts.
We believe that a continuation of the current project (95/80) is the best approach to further tackle this Y-chromosome marker issue. It will allow us to best utilise the expertise and momentum we have established on this problem, rather than completed our current objectives and then revisit this issue in a year or two.
If we are successful in locating a Y-chromosome marker either during the remainder of the current schedule or early in the 1997 grant extension, resources will then be directed to isolate and further characterize that marker. Objectives: 1. To locate a Y-chromosome marker in Atlantic salmon by applying a range of molecular genetic techniques. 2. To establish the rate of change in genetic variation in Tasmanian Atlantic salmon by comparing the genetic (microsatellite and allozyme) variation expressed in progeny from 1993 year-class parents with that present in 1989 year-class parents and the parental Nova Scotia population.
