Ketut Suwirya visited CSIRO’s Division of Marine Research Laboratories atCleveland, Queensland, from 4–24 June 2000 and trained with Dr Kevin Williamsand Ms Maggie Barclay on analysis techniques for fatty acids, utilising Artemiasamples from the larviculture research component of the project at NFC. Mr Suwiryaalso visited DPI’s Bribie Island Aquaculture Research Centre and a Penaeusjaponicus farm on the Logan River during his stay at Cleveland.Training for staff at SEAFDEC has been postponed until later in the project. It wasdecided that SEAFDEC staff have adequate training in the chemical analysistechniques relevant to the project, and that the training budget would more usefully beutilised later in the project. This is now likely to involve cross-training in enzymeanalysis techniques, with Gerry Quinitio visiting NFC Cairns to work with ShannonMcBride on fluormetric analysis techniques, and Shannon visiting SEAFDEC AQD towork with Gerry and Perla Eusebio on spectrophotometric techniques.Following discussion with staff at RICF Maros, it was decided that the nutritionteam’s training needs would be best met by providing training in assessing thedigestibility of feed ingredients, and that this could be met by Dr Geoff Allan’s teamat New South Wales Fisheries Port Stephens Research Centre. This training will nowbe carried out in August-September 2000, when Dr Allan is running digestibility trialsas part of on-going research projects.RICF Maros also proposed some additional training, which can be carried out inIndonesia or at other laboratories in the region. Reni Yulianingshih will attend GajahMada University (Yogyakarta, Indonesia) for training in chemical analysis techniquesfor nutrition studies. Taufik Ahmad has requested that Asda Laining be trained innutrition research, preferably in Australia.The agreed training activities are summarised below.Centre Aspects Staff PlaceSEAFDEC Digestive enzymeassessmentGerry QuinitioShannon McBrideNFC CairnsSEAFDEC AQDRICF Maros Digestibility offeed ingredientsRachmansyah PSRC, Port Stephens[Aug-Sep 2000]Chemical analyses ReniYulianingshihGajah Mada University,Yogyakarta [Sept 2000]Grow-out nutrition Asda Laining (to be identified)/ chemical analysisRSCF Gondol NutritionalanalysesKetut Suwirja CSIRO, Cleveland[completed]1.3 Calibration exerciseThere was good agreement between most laboratories for routine proximate analyses.Exceptions were for ash analyses where values for squid meal were highly variablebetween laboratories. Laboratories 9904 and 9905 tended to be give higher ash valuesfor fish, squid and soybean meals than the other laboratories. In the case of laboratory9904, this could be attributed to the low incinerating temperature used (450 vs 550 o C)which was the standard protocol in this laboratory for ashing live feeds samples.There was no obvious reason for the apparent variable ash results for laboratory 9905.ACIAR Project FIS/97/73 – Annual Report – June 2000 9
