    Description: KurzfassungZahlreiche Fischereierzeugnisse aus dem Deutschen Handel wurden auf ihren Gehalt an Cholesterol hin analysiert. ZurAnalyse gelangten 38 verschiedene Dauerkonserven von acht Fischarten, 4 Produkte kalt geräucherter AtlantischerZuchtlachs in Scheiben, 10 Garnelenarten und 25 Fischstäbchenerzeugnisse von 5 Tierarten in Verbraucherpackungen. Bei den Dauerkonserven lagen die Gehalte zwischen 24 und 40 mg/100 g. Zwei Ausnahmen bildeten Sprottenkonserven mit durchschnittlich 107 mg/100 g und Oktopuskonserven mit 196 mg/100 g. Die Garnelenarten variierten zwischen 84 und 161 mg/100g. Die kalt geräucherten Lachsscheiben wiesen nur eine kleine Bandbreite im Cholesterolgehalt zwischen 38 und 43mg/100 g auf. Alle Fischstäbchen aus Magerfischen enthielten niedrige Gehalte an Cholesterol (Pangasius hypophthalmus 25, Seehecht 19, Seelachs 31 und Alaska Seehecht 28 mg/100 g), während die zwei Proben aus Tintenfischen über 100 mg/100 g lagen.AbstractNumerous fishery products from the German market have been analysed for their content of cholesterol. In total 38 different canned fishery products produced from 8 species, 4 products of sliced cold smoked Atlantic salmon, 10 species of crustacean shellfish and 25 different brands of consumer packages of fish fingers (produced from 5 species) were investigated. Canned fishery products contained amounts of cholesterol ranging from 24 to 40 mg/100 g. However, canned sprats exhibit cholesterol content as high as 107 mg/100g and canned octopus 196 mg/100 g. Crustacean shellfish was found to contain cholesterol content between 84 and 161 mg/100 g depending of species. Sliced cold smoked salmon in 200 g consumer packages showed only a little variation in cholesterol content (38-43 mg/100 g). In all fish fingers produced from lean fish species lowcholesterol content (pangasius or sutchi catfish 25, hake 19, saithe 31, and Alaska Pollack 28 mg/100 g, respectively) was found, whereas two products produced from squid exceeded 100 mg/100 g.

    Description: There is compelling evidence that increased gender equity can make a significant contribution towards alleviating poverty and increasing food security. But past efforts to integrate gender into agricultural research and development practice have failed to address the inequalities that limit women’s access to agricultural inputs, markets, resources and advice. A Gender Transformative Approach (GTA) goes beyond just considering the symptoms of gender inequality, and addresses the social norms, attitudes, behaviors and social systems that underlie them. The CGIAR Research Program on Aquatic Agricultural Systems (AAS) has placed the GTA at the heart of its gender strategy. This workshop was an opportunity for researchers, practitioners and donors working in this area to address the challenge of how to translate this approach into actual research and development practice. The workshop recommended that a GTA should be adopted alongside, not instead of, existing efforts to reverse gender disparities in resources, technologies and markets. It is through this pairing that improved social and material outcomes can be achieved, with the expectation that when achieved together, both types of outcomes will be more lasting than if achieved individually.

    Description: To ensure the authentication of fishery products lacking biological characters, rapid species identification methods are required. Two DNA- and protein-based methods, PCR-SSCP (polymerase chain reaction - single strand conformation polymorphism) of a 464 bp segment of the cytochrome b – gene and isoelectric focusing (IEF) of water-soluble proteins from fish fillets, were applied to identify fillets of (sub-) tropical fish species available on the European market. Among the samples analysed weretwo taxonomically identified species from the family Sciaenidae and one from Sphyraenidae. By comparison of DNA- and protein patterns of different samples, information about intra-species variability of patterns,and homogeneity of batches (e.g. fillet blocks or bags) can be obtained. PCR-SSCP and IEF may be useful for pre-checking of a large number of samples by food control laboratories.ZusammenfassungZur Sicherstellung der Authentizität von Fischerei-Erzeugnissen ohne biologische Merkmale sind schnelle Verfahren zur Speziesidentifizierung hilfreich. Zwei Methoden der DNA- bzw. Protein-Analyse wurden eingesetzt, um Filets (sub-) tropischer Fischarten, die auf dem europäischen Markt angeboten werden, zu identifizieren. Bei diesen Methoden handelt es sich um die PCR-SSCP (Polymerase-Kettenreaktion – Einzelstrang-Konformationspolymorphismus) – Analyse der PCR-Produkte und die IEF (isoelektrische Fokussierung) der wasserlöslichen Fischmuskelproteine. Unter den untersuchten Proben waren zwei taxonomisch bestimmte Arten aus der Familie Sciaenidae und eine Spezies aus der Familie Sphyraenidae. Durch Vergleich der DNA- bzw. Proteinmuster lassen sich Informationen über die intra-spezifische Variabilität solcher Muster und die Einheitlichkeit von Partien (beispielsweise Filetblöcke oder Filetbeutel) gewinnen. PCR-SSCP und IEF könnenin Laboratorien der Lebensmittelüberwachung als Vortest gerade bei hohen Probenzahlen sinnvoll eingesetzt werden.

    Description: The WorldFish Center was tasked to undertake a study to access, collate and develop background materials to produce an internationally linked and Africa-wide perspective on sectorally relevant policy issues. The specific objective of the study was to assess and define conditions and impact pathways, in Africa or elsewhere, where markets, policies, resources and technologies have combined to promote steady and sustainable growth of aquaculture, and where have been clear direct impacts on food supply, income, employment and consumption opportunities, as well as increase in supply that has led to stabilised prices. The study was also aimed at providing guidelines for scaling up the implementation of the synthesis study via Afri-FishNet (CAADP Fish Expert Pools) at the national and regional levels.
