Summary

Fish contain an array of oils, which vary markedly between species. The waste, by-catch and by­products from the Australian :fishing industry can therefore be value-added to yield a range of marine oils. It is estimated that 100 000 tonnes per annum of the Australian fish catch goes to waste. Research from this Project ( and its forerunner 91/77) has focused on oil from deep water and pelagic fish, and as a result of this work several companies have commenced production of marine oils for export and local use. Our research involved characterization of marine oils from Australian species, searching for new sources of commercially sought-after oils, development of new or refinement of existing processes suitable for Australian oils, and transfer of know-how to industry. Strong links exist with industry, giving an increased return for both the fishermen and oil processors, without increasing catch effort. Oils examined include: (i) wax esters derived from orange roughy, oreo dories and other fishes, (ii) shark liver oils containing squalene and diacylglycerol ethers, and (iii) triacylglycerol oils rich in essential omega-3 fatty acids. The oils are used as lubricants, in degreaser and hand cleaner products, in cosmetics and nutraceuticals.

The strengths of the Australian Marine Oils industry include: (i) relative sustainability of raw material (some countries show resources in decline), (ii) a clean and green image of the local resource, (iii) closeness to Asian markets, (iv) uniqueness of composition of several marine oils, (v) an increasing knowledge of marine oils and (vi) development of appropriate technologies. Opportunities exist based on these strengths and the Marine Oils industry has taken several products into the international market place. Together these features provide the Australian fishing and associated industries with the capacity to better utilize existing resources.

Summary

This report describes an ex-post cost/benefit analysis on two FRDC projects:

•  1991-077, Orange Roughy and Other Marine Oils: Characterization and Commercial Applications; and
•  1994-115, Marine Oils from Australian Fish: Characterization and Value Added Products.

The initial 1991 project was framed in the context of the boom orange roughy catches of the late 1980s-early 1990s and widespread concern over the amount of wastage that was occurring in terms of the landed orange roughy catch and the deep water sharks that were taken as bycatch by the orange roughy fleet.

Accordingly, project 1991-077 was focused on characterising the oil composition of orange roughy, oreo dories and deep sea sharks, on identifying processing techniques to extract and purify orange roughy and shark liver oils, and on identifying potential commercial products based on orange roughy-type oils and shark liver oils.

Project 1994-115 continued these general themes, though with less focus on the orange roughy-type oils and greater emphasis on the polyunsaturated omega-3 type fish oils. New species were characterised - with particular reference to their omega-3 content - and attention was given to developing processes to purify omega-3 type oils. The shark liver work continued - more species of shark were characterised - and further efforts were made at improving processes to extract and purify shark liver oils.

SCRC: Optimising harvest practices for Yellowtail Kingfish

Need

Ultimately, the need is to make the production of farmed YTK a profitable enterprise. To this end it is necessary to not only reduce the cost of production by improving harvest efficiencies, it is necessary to improve the consistency and overall quality of the product so as to justify a quality driven increase in the farm gate price of the product. Understanding how harvest husbandry techniques influence flesh quality attributes will allow CST to develop and apply best practice standard operating systems, reduce customer complaints and improve the company’s position in a competitive market.

Summary

Farmed Yellowtail Kingfish (YTK) is considered to be a premium quality fish, ideal for sashimi and sushi, dishes comprised of raw fish. To be acceptable for such delicacies the flesh has to be oily, firm and slightly translucent, with a fine creamy texture and a delicate flavour. The price received, and the reputation of the supplier, are largely dependent on the quality of the product produced. Therefore it is of great interest to optimise the production of high quality fish, especially in the increasingly competitive white fish market.

This project sought to investigate several issues relating to commercial harvest practices for Yellowtail Kingfish, with the aim of modifying any aspect to improve product quality and/or harvesting efficiency.

Identification of a Y-chromosome marker in Atlantic salmon (extension to FRDC 95/80)

The aquaculture of Atlantic salmon began in Australia in the mid-1960' s with an importation of ova from Canada to New South Wales. Anecdotal evidence suggested that the Australian population went through a severe bottleneck event during the early years due to poor survival and subsequent small...
