    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.

    Pacific oyster farming
    A practical manual
    2024
    Also available in:
    No results found.
    The purpose of this manual is to give the reader a foundation of practical knowledge regarding all aspects of Pacific oyster cultivation. It is targeted at new entrants to the market wishing to establish a farm, and existing operators who wish to develop their farms and explore new cultivation techniques. The methodologies described can be applied both to low-tech, low budget, small-scale farming operations and to high-tech, big budget, industrial-scale aquaculture production enterprises. This guide focuses on the functional expertise and technical equipment required to construct and manage an operational farm in the diverse environmental and physical locations in which they can be situated, from the initial stages of finding and selecting a suitable site, to the conclusion of the first production cycle and harvesting the crop. The manual contains a brief introduction which describes the relevance of the species with regards to global aquaculture production figures and how it can form an important part of future food production strategies. Chapter 2 describes the anatomy and biology of Crassostrea gigas and gives an indication as to the environmental conditions in which the species thrives as well as the pathologies and predators that can result in poor health leading to potential mortalities. Chapter 3 deals with all aspects of undertaking a survey of potential oyster farming sites and what data should be collected and examined to assess a site’s suitability, but also which areas are best suited to different cultivation techniques. After this, Chapter 4 introduces the main farming techniques that will be described in detail in the following chapters, which includes off-bottom cultivation, on-bottom cultivation, and suspended cultivation, and gives details of some of the most common cultivation equipment necessary to undertake these operations. The techniques and strategies necessary to procure seed oysters and how to develop them through the nursery stage are also introduced. This includes the basic principles of upwelling, which then leads into Chapter 5, which provides a detailed description of how to build and operate one particular example of a Floating Upwelling System (Flupsy) which is suitable for use in remote but sheltered conditions. Chapters 6, 7 and 8 constitute the main body of the manual and provide an in-depth look into the three major cultivation techniques that this guide concentrates on: “Farming with trestles and bags in the intertidal zone”, “On-bottom cultivation in the intertidal or subtidal zone” and “Offshore longline cultivation”.
