The ASFB workshops play a key role in delivering these objectives, and the 2006 workshop theme of ‘Cutting-edge Technologies in Fish and Fisheries Science’ was a timely one. In the face of shrinking research budgets and increasing pressure on fisheries, the need to find smart and innovative solutions to research and management questions has never been more apparent. As fisheries management is becoming increasingly more sophisticated, so the science and research underpinning management must also be leading edge. There have been significant advances in recent years on a range of fisheries investigation tools and techniques, and Australian fisheries researchers have been at the forefront of a number of these. Approximately 230 delegates attended the workshop, including a large number of students; the future of fisheries science. The workshop organising committee assembled an outstanding program of 28 international and national presenters covering a diversity of cutting edge techniques grouped under four themes: • Tagging and tracking • Underwater vision and hydro-acoustics • Chemical techniques, and • Data capture and management. I particularly thank Ron O’Dor and Pamela Mace, for their stimulating Plenary addresses, and the other keynote speakers and panellists for their efforts. The 2006 organising committee, headed by Jeremy Lyle and Dianne Furlani, did a sterling job in ensuring the workshop ran smoothly, along with the timely production of the workshop proceedings. I am sure that all delegates will have emerged from the workshop with some new ideas for future studies and collaboration, and the prompt delivery of the workshop proceedings provides a valuable resource for both new and experienced players to build upon such ideas. 2006 also represented the 21st anniversary of the commencement of the ASFB workshop series, with the first workshop held in Melbourne in 1985 on threatened fishes. The workshop series has developed into a much anticipated fisheries event on the Australian calendar, with the workshop outcomes influencing fisheries science for many years. The workshop series is reliant on the support of corporate and agency sponsors and I thank the Fisheries Research & Development Corporation for their continued support of the ASFB workshops. FRDC was again the Principal Sponsor for the 2006 workshop, along with twelve Major Sponsors and seven other Sponsors. 2006 also represented the milestone of 35 years since the Society was formed. In 1971 the ASFB started with 79 members, and has now grown to in excess of 500 active members. The strength of the Society is in its membership, and I encourage all members to actively participate in the business of the ASFB. This means not just attending the workshops and conferences, but also participation in the various committees and at the AGM.

  • Extraction and Optimization of Biodiesel Yield from Wax Esters of Apis Melifera (Honey Bee) *Hariram V and Bharathwaaj R
    International Journal of ChemTech Research CODEN (USA): IJCRGG ISSN: 0974-4290 Vol.8, No.9 pp 433-437, 2015 Extraction and Optimization of biodiesel yield from wax esters of Apis melifera (Honey Bee) *Hariram V and Bharathwaaj R Department of Automobile Engineering Hindustan Institute of Technology & Science, Hindustan University, Chennai, Tamil Nadu, India Abstract: Wax esters from Apis melifera (honey bee) is studied in this research article for extraction of Biodiesel. The study shows that the long chain mono-alkyl ester from the beeswax is transformed into small chain methyl esters by a two stage trans-esterification reaction. Primary stage constitutes of acid catalysed esterification in which Wax Esters, Methanol and Concentrated Hydrochloric acid is used to reduce the free fatty acids. Base catalysed esterification is followed with treated wax ester, Methanol and catalyst at the ratio of 4:1:0.02. An optimization study was conducted with changing the catalyst (Sodium Hydroxide and Potassium Hydroxide), reaction temperature and molar ratio. It is found that at molar ratio 1:0.25, reaction temperature 60oC, Sodium Hydroxide concentration of 0.02% by weight, yielded 85% of Biodiesel. Keywords: Wax Esters, Trans-esterification, Biodiesel, Animal fat. 1. Introduction Nowadays, the engineering world is encountering dual crisis, one on depletion of fossil fuel and the other on hazardous environmental pollutant. It is very important for today’s world to identify an alternative to fossil fuel to meet the future demands for energy. Researchers identify four major sources of energy which would replace the fossil fuels to the considerable level namely vegetable oils, used vegetables oils, animal fats and oleaginous micro-organisms.Biodiesel is found to have gained qualitative attractions by many researchers due to their comparable physio chemical properties with petro diesel, reduced environmental effects and their renewability [1,2].

  • The Biology and Ecology of Samson Fish Seriola Hippos
    The biology of Samson Fish Seriola hippos with emphasis on the sportfishery in Western Australia. By Andrew Jay Rowland This thesis is presented for the degree of Doctor of Philosophy at Murdoch University 2009 DECLARATION I declare that the information contained in this thesis is the result of my own research unless otherwise cited. ……………………………………………………. Andrew Jay Rowland 2 Abstract This thesis had two overriding aims. The first was to describe the biology of Samson Fish Seriola hippos and therefore extend the knowledge and understanding of the genus Seriola. The second was to uses these data to develop strategies to better manage the fishery and, if appropriate, develop catch-and-release protocols for the S. hippos sportfishery. Trends exhibited by marginal increment analysis in the opaque zones of sectioned S. hippos otoliths, together with an otolith of a recaptured calcein injected fish, demonstrated that these opaque zones represent annual features. Thus, as with some other members of the genus, the number of opaque zones in sectioned otoliths of S. hippos are appropriate for determining age and growth parameters of this species. Seriola hippos displayed similar growth trajectories to other members of the genus. Early growth in S. hippos is rapid with this species reaching minimum legal length for retention (MML) of 600mm TL within the second year of life. After the first 5 years of life growth rates of each sex differ, with females growing faster and reaching a larger size at age than males. Thus, by 10, 15 and 20 years of age, the predicted fork lengths (and weights) for females were 1088 (17 kg), 1221 (24 kg) and 1311 mm (30 kg), respectively, compared with 1035 (15 kg), 1124 (19 kg) and 1167 mm (21 kg), respectively for males.

NCIB 8250. It also describes the effects of these different growth conditions on the fatty acid composition of both the wax esters and the phospholipids found in this bacterium. 2 When Acinetobacter sp. NCIB 8250 was grown in continuous culture at 30 °C under ammonium limitation the wax ester content was significantly greater at low specific growth rates [approximately 4 0 -4 5 mg (g dry weight)"1] than at specific growth rates approaching the maximum specific growth rate [ 1 - 2 mg (g dry weight)'1].

  • Studies on Wax Esters in Fish
    STUDIES ON WAX ESTERS IN FISH Until 1978, New Zealand only had access to fisheries close to the shore, but since then there has been exclusive access to anywhere within 320 km of the coastline. This has made available many deep-water fisheries, and many fish are commonly caught in these that were rarely able to be caught previously. Although these fish are mainly caught for their flesh, it has been found that they have very high levels of substances known as wax esters among their oils. Wax esters are esters (RCOOR') with up to thirty carbon atoms and at most one double bond. They form a lens on water instead of spreading out like other oils, and are less viscous than hydraulic oil although they share many other properties with it. Wax esters are usually obtained either from spermaceti oil or the oil of the Jojoba plant, but as these sources are both highly limited New Zealand deep-water fish are a valuable source of these esters. These esters have a variety of uses in many industries. They can be used as high pressure lubricants, replacing hydraulic oil, and in the pharmaceutical, cosmetic, printing and leather industries, as well as in candles and polishes. The commonest fish oil used to obtain wax esters is that of the orange roughy, although other fish are also suitable. New Zealand is currently the only country extracting wax esters from fish oil, although some other countries also have suitable fish in their waters. INTRODUCTION The term 'wax esters' includes all esters of long chain carboxylic acids with long chain alcohols.
