Obiettivo
The aims of the projects are :
to analyse economic feasibility of eel farming in intensive systems in general and to quantify the effect of technical and biological factors on this feasibility. Secondly to evaluate to what extend the EC subsidy-policy for aquaculture has contributed to or will contribute to development of eel farming in Denmark and The Netherlands.
to analyse bottlenecks in the biological and technical design of intensive eel farms and their impact on the profitability of eel farming in general.
Data have been collected from eels farms on technical, biological and economical aspects mainly by means of questionnaires. The physical capacity of most farms in terms of maximum standing stock and feed load per day is sufficient to enable the projected production. Measurement of flows in farms have demonstrated that these are in general considerably less than planned due to bad design. Optimization of the output of pumps in existing systems will enable larger standing stocks to be kept and improve profitability.
Biological data on growth, feed conversion and density have been collected based on the grading data of farms. The growth figures show that the growth of eels is often overestimated. At least 9 months are needed on average to go from 15 to 150 g giving growth rates of a total ideal standing stock of 0.75% per day.
Overall feed conversion ratios vary between 1.43 and 2.65 indicating that in this field there is a lot to be gained for most farmers.
Costs and earning of the farms participating were extensively analysed. Moreover a simulation model with input of collected data from 1 year has been used to analyse economic feasibility in the long term and to perform a sensitivity analysis.
Net losses in the first few years are inevitable. The question is to what extent these losses are acceptable and can be earned back. To analyse this, a minimum loss and profit path for a period of 10 years has been estimated.
The economic simulation model shows that the output of an eel farm is extremely sensitive to changes in eel growth rate. The main reason for the poor economic performance can be attributed to overestimated growth rates in the planning period. Better planning of the production with emphasis on biological and technical items that could enhance growth is needed.
The programme contains an economical part covered by LEI (Netherlands) and DIFER (Denmark) and a biological /technical part covered by RIVO (Netherlands) and DAI (Denmark). Since most of the recent developments in intensive eel farming occur in Denmark and The Netherlands a comparable programme will be executed in both countries.
The economic research will be aimed at an evaluation of the economic viability of intensive eel farming. The economic research will involve the following activities:
Formulation of a questionnaire in order to obtain economic information from eel-farmers and eel-wholesalers. Contacts with farmers and wholesalers and their organisations will be established in the spring of 1989. Information from wholesalers will be used to obtain data on developments of the market and prices for farmed eel in the future. In this phase statistics on imports and exports of eel will be obtained.
Collection of the economic data from the farms in 1989 and the beginning of 1990.
Construction of a computer model for economical calculations.
Processing of the collected data and of the input from the biological technical research.
Evaluation of the viability of several types of farms and execution of a sensitivity analyses with the most important parameters for economic viability using collected empirical data and the computer model.
The biological/technical part of the programme will be directed towards the identification of bottlenecks in the biological and technical design of eel farms. This part of the programme will also produce some of the main input for the economical evaluation like growth and production data. This part of the research will involve the following activities:
Farmers and their organisations will be approached jointly with the people performing the economical research in order to obtain relevant biological and technical information. Data will be collected covering at least a period of one year on specific growth rates, stocking density, feed conversion, consumption of water, oxygen and energy, water quality, diseases and technical problems.
Collection of data from the farms and water quality analyses in 1989 and the beginning of 1990.
Processing of the collected data and evaluation of the results
