Bericht über vergleichende Untersuchungen zur Lagerung von Fischfilet in konventionellen und mit Silbernanopartikeln beaufschlagten Verpackungen

Kurzfassung Die Lebensmittelbranche erwartet durch den Einsatz von Nanotechnologien hervorragende Fortschritte bei der Verbesserung der Produktqualität und der Lebensmittelsicherheit. Vor diesem Hintergrund wurde 2009 am Max Rubner Institut der Fach- und Institutsübergreifende Forschungsschwerpunkt „Nanotechnologie“ etabliert, um Grundlagen zu erarbeiten, aufgrund derer die Auswirkungen der Nanotechnologie auf Lebensmittel und damit die Ernährung und Gesundheit der Verbraucher beurteilt werden können. In diesem Forschungsprojekt wurde der Einfluss neuer, mit Nanopartikeln beaufschlagter Verpackungsfolien auf Fischfilet untersucht. Abstract: The food industry expects by the application of nanotechnology excellent progress in the improvement of the product quality and the food safety. On this background the Max Rubner Institute established in 2009 an interdisciplinary focus on nanotecchnology research to formulate principles upon which the impact of nanotechnology on food and thus the nutrition and health of consumers can be assessed. In this research, the impact of new, nanoparticles containing packaging films was examined for fish fillet.

Regional study on social dimensions of MPA practice in Central America: cases studies from Costa Rica, Nicaragua, Honduras and Panama

This research focuses on the social dimensions of marine conservation, and makes an assessment of the experiences of coastal and fi shing communities with regard to the governance of MPAs in Central America, based on case studies from Honduras, Nicaragua, Costa Rica and Panama. It examines the national contexts of the above countries in relation to the governance of MPAs. Furthermore, it analyzes the social impacts of MPAs on coastal communities by gathering the experiences and the voices of the communities and institutions involved, and reflects on how to build bridges in the search for forms and models of conservation that respect human rights and which are able to successfully integrate into local development efforts without affecting cultural and/or social patterns. To this end, this monograph looks at nine case studies across the region: in Honduras, the Islas de la Bahia-Guanaja Marine National Park, the Cayos Cochinos Marine Archipelago Natural Monument, and the Cuero and Salado Wildlife Refuge; in Nicaragua, the Chacocente Wildlife Refuge; in Costa Rica, the Guanacaste Conservation Area, the Ballena Marine National Park and the Golfo Dulce Responsible Fishing Area; and, in Panama, the Nargana Protected Area, in the Comarca de la Biosfera Guna-Yala, the Bastimentos Island Marine National Park, and Bocas del Toro.

Estudio regional sobre las dimensiones sociales en el manejo de areas marinas protegidas: casos en Costa Rica, Nicaragua, Honduras y Panama

Explora la percepción de las personas residentes en las comunidades costeras vinculadas a los espacios marinos protegidos en Honduras, Nicaragua, Costa Rica y Panamá. Profundiza, a partir de estudios de caso y el análisis comparativo, los temas de gobernanza, derechos humanos y distribución justa y equitativa de beneficios derivados de la conservación. Los resultados destacan que los esfuerzos de conservación marina no han logrado establecer puentes que permitan satisfacer las necesidades sociales. Las comunidades han sido excluidas de los procesos de toma de decisiones, y los costos de la conservación han recaído en las pueblos costeros. Se plantean recomendaciones orientadas hacia el desarrollo de procesos de conservación marina y desarrollo local en aras de tender puentes en la búsqueda de formas y modelos de conservación marina que sean respetuosos de los derechos humanos y promuevan “el buen vivir” de las comunidades en territorios marino-costeros.

Water quality studies of the Delaware River with reference to shad migration

For some time pollution of the waters of the Delaware River by municipal and industrial wastes has been suspected of playing a major role in the decline of the shad fishery. Accordingly, studies were planned to ascertain whether any conditions of water quality caused by stream pollution and harmful or lethal to shad were existant in the waters of the Delaware River during the migration periods of the shad.

Genetic status of selected fish taxa in relation to conservation of genetic and species diversity in the Victoria and Kyoga Lake basins

Cichlids are known for their explosive radiation especially in the African Great Lakes marked with a high level of lake endemism. These fishes have been characterized mainly along trophic and habitat differences, by variation in morphological structures such as teeth and jaws and by differences in body shape and coloration. Cichlids are important as a microcosm of macroevolution. The explosive radiation, young evolutionary scale, and the isolation of groups characterized with high levels of endemism and presence of living fossils makes the group important for evolutionary and genetic studies. Lake Victoria region cichlids which are isolated and relatively more recent in evolution were the last to be appreciated in their diversity. Recently Ole Seehausen has found scores of rock fishes in Lake Victoria which were up to then thought to be absent from the Lake and only known to occur in Lakes Malawi and Tanganyika. Greenwood put together the species groups of Lake Victoria, and later in the early 1980's revised the classification of haplochromine species to reflect the phyletic origin and interrelationship of the various groups in Lake Victoria region. Melan Stiassny has been interested in early evolution of cichlids while the likes of Paul Fuerst and Lees Kaufman and Axel Meyer have been interested and are working to explain the speciation mechanisms responsible for the explosive radiation and evolution of cichlids. Locally S.B Wandera and his student Getrude Narnulemo are spearheading the biodiversity and taxonomic studies of cichlids in Lake Victoria region

A note on some parasites of Merluccius capensis (Pisces) and their zoogeographical significance

During the Southeastern Atlantic Expedition of the German fishery research vessel "Walther Herwig" in 1967 the main emphasis lay on selective fishing of the South African hake Merluccius capensis (von BRANDT 1967). Some of the fish were found to be infested by ecto-and endoparasites both of which were collected whenever possible. Large plerocercoids of Dibothriorhynchus grossum whose adult stage lives in the South Atlantic Ocean in Lamna cornubica (L.SZIDAT, personal communication) were quite common as were cysticercoids of a Tetrarhynchus sp., which had also been reported in Cynoscion striatus off the Argentinian coast (MACDONAGH 1927, cited in Szidat, personal communication). Brownish nematodes were infesting the ovaries of several fish, but could not be identified. The most common ectoparasite to be observed was the parasitic isopod Livoneca raynaudii (fam. Cymothoidae) whose early larval stages were also found.
