Responsible fish utilization

These guidelines have been produced to support the implementation of the Code of Conduct for Responsible Fisheries particularly with regard to the need for responsibility in the post– harvest sector of the fish producing industry. The industry that produces fish for food has three major areas of responsibility: to the consumer of the food to ensure that it is safe to eat, is of expected quality and nutritional value, to the resource to ensure that it is not wasted and to the environment to ensure that negative impacts are minimized. In addition the industry has a responsibility to itself to ensure the continued ability of many millions of people throughout the world to earn a gainful living from working within the industry. Article 11.1 of the Code of Conduct for Responsible Fisheries and other related parts of the Code are concerned particularly with these responsibilities. This publication provides annotation to and guidance on these articles to assist those charged with implementation of the Code to identify possible courses of action necessary to ensure that the industry is conducted in a sustainable manner.

WEFTA-Laborvergleichsuntersuchungen zur pH-Bestimmung in Fischerei-Erzeugnissen - Eine gemeinsame Aktion der Western European Fish Technologists' Association

12 samples (6 original samples and 6 diluted samples) were analysed by 14 WEFTA laboratories for their pH values in an inter-laboratory comparison exercise. As a result it can be stated that the majority of participating laboratories could determine the pH values very exactly. The pH values obtained are ranging only little around the calculated mean (less than 0.1 pH unit). It could also be demonstrated that the participating institutes could analyse both, pH values in fishery products and aqueous salt solutions. However, also in this exercise a number of outliers and deviating values have been detected. Therefore it is of utmost importance to calibrate the pH electrodes in regular intervals and to maintain them carefully. Intra-laboratory comparison measurements are recommended to detect weak points.

32. Jahretagung der West European Fish Technologists Association

Die West European Fish Technologists Association (WEFTA, gegründet 1970) ist ein Zusammenschluß von Europäischen Insti-tuten, die auf dem Gebiet Fischerei, Fischqualität und -verarbeitung arbeiten und forschen. Ziele der WEFTA ist der Informa-tionsaustausch zwischen Wissenschaftlern und Fischindustrie sowie die Ausweitung und Verbesserung der Zusammenarbeitunterschiedlicher Interessengruppen und Instituten in Projekten.

30. Jahrestagung der "WestEuropean Fish Technologists' Association" in Torshavn, Faroer

In der West European Fish Technologists’ Association (WEFTA) arbeiten zahlreiche europäische Institute zusammen, die sich mit Fisch als Lebensmittel oder mit Fischtechnologie befassen. Ziel der WEFTA ist es, einen Austausch von Informationen über Forschung und ihre Ergebnisse europaweit möglich zu machen. Die Jahrestagungen sind eine gute Gelegenheit, Einblick in die Arbeiten anderer Institutionen zu erhalten und europäische Kontakte zu knüpfen. Die Tagungen sind besonders interessant für junge Wissenschaftler, die hier ihre Ergebnisse einem grösseren Publikum vorstellen konnen.

31. Jahrestagung der "West European Fish Technologit´s Association" in Espoo, Finnland

Vom 27.-31. Mai 2001 fand in Espoo, Finnland, die 31. Jahrestagung der WEFTA (West European FishTechnologist’s Association) statt. 75 Teilnehmer aus15 europäischen Ländern, der FAO und der Europäischen Kommission sowie aus den USA und Kanadawaren der Einladung des VTT Biotechnology, eines großen finnischen Forschungsinstituts auf dem Gebiete der Biotechnologie und biologischer Materialien, zu dieser Tagung gefolgt. Die Durchführung in einemKongresszentrum in Espoo, nahe der finnische Hauptstadt Helsinki direkt am Bottnischen Meerbusen gelegen, ermöglichte einen straffen organisatorischen Ablauf und die Einhaltung des Zeitplanes der mit 41 Vorträgen und 18 Postern recht umfangreichen Veranstaltung, die in 7 Themenkomplexe gegliedert war. Nachfolgend werden wesentliche Ergebnisse der einzelnen Beiträge zusammengefasst

Strategies for increasing freshwater fish production in the Green Revolution Programme

Sources of fish and fishery products in Nigeria were reviewed. The problems of various agencies involved in freshwater fish production in Nigeria were also analysed, such problems included shortage of manpower, inadequate training for personnel, shortage of funds, lack of infrastructures, among others

Developing a viable fish farming industry in Nigeria -- an alternative strategy to the strategy in the Green Revolution Programme

A study was embarked upon with the twin objectives of reviewing the Green Revolution Strategy for accelerating fish production in the country and proposing an alternative strategy, a private sector approach. Some of the programmes listed in the Green Revolution are very necessary for developing a viable - fish farming industry and that money spent under such programmes is money well spent. Programmes that are also desirable but need to be considerably expanded were identified. Other programmes have been criticised on the grounds that the method chosen to achieve the desired objectives is fraught with dangers if sufficiently long run view of fisheries development is taken

Strategies for transfer of aquaculture technology to small-scale fish farmers in Nigeria

There is increasing awareness of aquaculture in Nigeria today for a number of reasons namely: water pollution, declining catch and the awareness of the attractiveness of aquaculture as an investment area and a pivotal point for national development. The development of aquaculture in Nigeria, requires the building up of institutions at the grassroot level and the formulation of policies and programmes for the small fishfarmer. This of course would be backed up by a sound technology generation, verification and packaging, dissemination and use programme

Preliminary studies of the dual role of cotton-seed cake as fish feed and fish pond fertilizer in aquaculture

Many locally available fish feeds have been tried in fish culture. These include guinea corn, soya bean, groundnut cake and rice bran. Cotton seed cake has been successfully used as a fishpond organic fertilizer at Ado-Ekiti Government fish farm. Three fishponds stocked respectively with common carps, Heterotis, Tilapia spp., Clarias lazera and Heterobranchus were fed with cotton seed cake. Carps, Tilapia and Heterotis increased rapidly in weight and length while the catifishes did not grow

A quantitative analysis of demand for fish in Nigeria

The paper discusses the relevant theoretical considerations and specifies a model in an attempt to quantify those variables, the changes of which affect the internal demand for fish in Nigeria. Regression analyses carried out show that a generally rising trend in per capita income will increase the demand for fish, other things being equal. It is further revealed that even as the price of fish goes on increasing, consumers' demand for fish also tend to rise. The paper concludes by emphasizing the need for a fish consumption survey in the country's fish demand

A statistical investigation of fish prices in Nigeria

The main objective of this study is to describe and characterize the behaviour of fish prices in Nigeria. Drawing upon aspects of the data from a nationwide fish survey in 1980/81 and on various secondary data, the study analyses the pattern of fish price movement and makes projections of fish prices in Nigeria till 2002 A.D. It is concluded that unless efforts are directed at stemming inflation in fish prices, prices paid by fish consumers in Nigeria will be more than doubled within the next two decades

Preliminary observations of some smaller fish of the freshwaters of the Calabar area

About 43 species of fish from sites within approximately 50 km north and 100 km northeast of Calabar are listed. Brief ecological and taxonomic data for some of the species are given

28. Jahrestagung der "West European Fish Technologists´ Association" in Tromsø, Norwegen

In der 1970 gegründeten West European Fish Technologists’ Association (WEFTA) arbeiten zahlreiche europäische Institute, die sich mit Fischen als Lebensmittel bzw. Fischtechnologie befassen, zusammen. Sie wurde seinerzeit ins Leben gerufen, um jüngeren Wissenschaftlern zu ermöglichen, ihre Ergebnisse und Probleme einem größeren fachkundigen Publikum vorzustellen gegebenenfalls weiter weisende Impulse zu erhalten. In ihr wird aber auch der Sachverstand der Institute zusammengeführt, was zu zahlreichen bi- und multilateralen Absprachen geführt hat, aus denen EU-finanzierte Forschungsvorhaben entstanden sind. Die Jahrestagungen der WEFTA sind deshalb gute Gelegenheiten, bei denen Wissenschaftler und Technologen aus verschiedenen Ländern ihre Kenntnisse und Informationen austauschen können, um globale und öffentliche Fragestellungen zu diskutieren und durch gemeinsame Forschungsvorhaben zu klären.
