No results found.The eel culture consultancy for FAO Project HUN/79/001 was carried out from 2 June to 1 August 1980 at the Fish Culture Research Institute (Szarvas). Major objectives of the consultancy were: to review on-going research work on eel culture; to assist the research team involved in developing efficient production technology for the experimental intensive eel-pond system designed in 1976; to develop improved eel diets and to assess the feasibility of developing intensive eel culture in Hungary usin g geothermal energy or warm-water effluents. It has been stated that since 1976 staff of the Institute made considerable progress in raising eel in plastic tanks in the recycling fish rearing plant. However, intensive rearing of elvers was endangered by the lack of additional aeration of the fish tanks. Two new experimental outdoor eel-ponds each 150 m2 were stocked with pigmented eels on 29 May 1980 with a density of 0.2 kg/m2 (about 600 pieces/m2). Through the joint efforts of the consulta nt and the research team involved, the traditional Japanese stagnant water eel culture method was successfully adapted to these ponds in spite of several obstacles caused by delays in construction of the water supply and aeration system. Modified eel diets have been developed using slaughterhouse wastes and an experimental programme was agreed upon to continue testing of these diets. The consultant visited Hortobágy State Farm where an existing concrete pond system and two artesian wells are offering year-round fish culturing possibilities. It has been stated that, with some remodelling of the pond system and installation of an appropriate aeration system, the facility could be used efficiently for eel culture, especially for elver raising. -

No results found.The fish disease consultancy for the FAO/UNDP Project HUN/79/001 was carried out from 1 to 29 July 1981 at the Fish Culture Research Institute (FCRI), Szarvas, Hungary. Major objectives of the consultancy were to review on-going research work on fish diseases; to assist the research team in formulation and initiation of expanded research work on bacterial fish diseases and immunological response of fish to bacterial infections, and introduction of methods for mass immunization. Research work on fish diseases has rapidly been given an assured status since 1976. At present bacteriological and immunological studies of fish diseases are being initiated. It is natural that, when freshwater fishes are cultured more intensively, they develop various diseases more frequently and the diseases become more prevalent. It is necessary to isolate and identify the pathogen of these diseases and at the same time to make studies to establish preventive and therapeutic methods against these diseas es. To protect fish from various bacterial diseases, it is first necessary to improve the technology for fish culture and to culture healthy fish which are highly resistant to diseases. Secondly, early treatment methods for fish diseases, as well as diagnostic procedures for early detection of fish diseases, should be established. Thirdly, it is necessary to make studies of artificial immunization with vaccines and to prevent diseases of cultured fishes. Then it becomes necessary to direct st udies to be made at the Institute for facilitation of studies in the three above mentioned fields. For this purpose, it is recommended that qualified research workers be trained and that facilities, equipment and supplies required be provided to fully support these studies. -
