5. Ridwan, M; Master degree of Hasanuddin University (Makassar) – replacement offish meal on humpback grouper diet including the digestibility of replacer.In addition, RICF Maros has hosted field trips and visits from local educationalinstitutions:• Student from Hasanuddin University (undergraduate and postgraduate) - discussthe sea farming in floating net cage particularly humpback grouper and milkfish.• Student from Aquaculture Program of Polytechnic in Pangkep Regency - discussthe sea farming aspects included the site selection, design construction of raft andcage, nutrition and feeding management as well as diseases.• TVRI Station of Makassar; hunting the location that potential for sea farmingdevelopment particularly for export commodity.• Mayor of Barru Regency, studying the model of sea farming of exportable fisherycommunity.Optimal methods / channels of extension / outreach of results to end-usersAll the participating organisations in FIS/97/73 have well developed extensionfacilities to assist with the application of research results.DPI has a range of effective extension activities in the field of aquaculture.Regular (currently six-monthly) workshops / conferences are held in associationwith the Australian Barramundi Farming Association which represents thetropical marine finfish farming sector in Australia. Technical outputs areprovided to industry at these workshops / conferences. In addition, dedicatedtechnical workshops on specific aspects of marine finfish culture are held on an‘as needed’ basis. Other extension activities provided by QDPI are:• publication three times per year of ‘Queensland Aquaculture’ Magazine,allowing widespread dissemination of research outcomes to the Queenslandaquaculture industry;• publication of technical material in a range of formats, such as the ‘GoingFarming’ series and the Information Series publications.DPI is holding a dedicated Reef Fish Aquaculture Symposium in conjunctionwith the ACIAR FIS/97/73 Project Meeting to be held in Cairns in late July2000. The Reef Fish Aquaculture Symposium will provide intending farmersand aquaculture investors with a ‘snapshot’ of the current status of reef fish /grouper aquaculture. About 30–40 people are expected to attend thissymposium.CRIFI utilises the services of the Assessment Institute for AgriculturalTechnology, which has an office in each province in Indonesia. AIAT isadministered by the Agency for Agricultural Research and Development, whichalso administers CRIFI. CRIFI research progress and outcomes are reported toAIAT at seminars and by direct contact. AIAT then extends research results toACIAR Project FIS/97/73 – Annual Report – June 2000 26
farmers through meetings and workshops. The development of small scalebackyard fish hatcheries for milkfish and seabass has provided RSCF Gondolwith experience in extending research results to industry. About 800 of thesehatcheries now operate in Bali, with many in the Gondol-Singaraja area. RSCFstaff are confident that these hatcheries will readily adopt grouper productiontechniques once the technology is commercially viable, due to the highprofitability of grouper larviculture.SEAFDEC operates a Technology Verification Program (TVP), which iseffectively a farm extension service. There are five SEAFDEC staff assigned toTVP. Most emphasis at the moment is on providing alternative technologies forthe shrimp farms in The Philippines that have gone out of operation because ofdisease problems. One alternative to shrimp farming that is being activelypromoted by TVP is grouper aquaculture. SEAFDEC held a ‘Grouper Festival’on the island of Negros in March 1998, to promote grouper aquaculturespecifically. According to SEAFDEC TVP staff, there is huge interest ingrouper aquaculture in The Philippines and the development of additionalgrouper farms is constrained only by the poor availability of fingerlings.A major component of this project is dedicated to ensuring that there is greatercooperation and exchange of information amongst grouper researchers and industrythroughout the Asia-Pacific region. Research outcomes from the ACIAR project, aswell as results from other research projects, are publicised in the dedicated ‘GrouperNews’ section of ‘Aquaculture Asia’ (published by NACA) and the ‘Live Reef FishBulletin’ (published by the Secretariat for the Pacific Community). The widespreadreadership of these established and respected publications will ensure widespreaddissemination of the results of the ACIAR project. This information is also providedon the NACA Grouper web site (http://naca.fisheries.go.th/grouper/) and outcomes ofthe ACIAR project are provided on the ACIAR project web site(http://naca.fisheries.go.th/aciar/). These mechanisms will ensure the widest possibleextension of the outcomes of this project, and will ‘value add’ the ACIAR project byaccessing the outcomes of other regional research projects to broaden the knowledgebase relating to grouper aquaculture technology.In addition, transfer of results to farmers and coastal communities is being activelysupported under the APEC grouper research and development project.Environmental impactsThe proposed research will potentially provide positive environmental impacts withregard to alleviating pressure on wild stocks that currently supply the bulk of the livereef fish markets. Currently, the demand for live groupers for the high value live fishmarkets of Hong Kong and southern China is being met largely by the capture fishery,and this fishery has been associated with unsustainable fishing practices, particularlythe use of sodium cyanide as a capture technique.The development of sustainable grouper aquaculture will contribute to the alleviationof adverse environmental impacts associated with unsustainable fishing practices byproviding an alternative source of supply which will assist in meeting demand forgrouper product. A specific strategy to develop grouper mariculture to reducepressures on wild stocks is being developed in collaboration with TNC in the Komodoregion of Nusa Tenggara Timur, Indonesia.ACIAR Project FIS/97/73 – Annual Report – June 2000 27
