| In a 7-week on-farm feeding trial rainbow trout(Oncorhynchus mykiss) were provided with a diet containing 28% mechanically de-fatted insect meal prepared from larvae of the black soldier fly, Hermetia illucens (HIM) and compared to a control that received a certified organic and fishmeal based diet. In the test diet insect meal replaced almost 50% of the fishmeal. The whole experiment was conducted under practical conditions on an organically certified rainbow trout farm in Switzerland. Fish of initially 66.5±2.3 g body weight were grown to 125±4.5 g and assessed for their growth performance, as well as analysed for their proximate composition, feed conversion ratio, fatty acid contents and organoleptic properties. Improved lipid utilisation and decreased... |

| This paper is the extended version of an oral presentation at a two day meeting questioning the way ish is currently produced for human consumption including isheries and aquaculture and the way ish might be produced in the near future. his paper gives an overview of the current status of ish welfare and tries to answer the question whether or not ish can be produced in an animal friendly way. Still, it is only a brief overview of a very complex topic which has been discussed for over three decades and which will be even more discussed in the future. Whole books have failed to answer the question mentioned above. Due to the complexity of the topic there is not an easy answer: the answer depends on many manmade deinitions. |

| Dieser Artikel soll einen kurzen Einblick in die Aquakultur, ihre Zusammenhänge mit der Fischerei, vergangene und aktuelle Probleme, Herausforderungen und Missstände sowie die biologische und nachhaltige Aquakultur liefern. Aufgrund der Komplexität des Themas, Aquakultur ist das Pendant zur Landwirtschaft, können die verschiedenen Aspekte jedoch nur kurz angeschnitten werden. Aquakultur ist die Produktion von Organismen im Wasser, unabhängig von der beabsichtigten Verwendung. Geographisch gesehen findet die überwiegende Produktion in Asien statt und die gesamte Produktionsmenge nimmt kontinuierlich zu im Gegensatz zur Fischerei, die seit Jahren stagniert, und macht Aquakultur damit zu dem am schnellsten wachsenden Lebensmittel produzierenden Sektor.... |

| Liquid manure from livestock production systems is a major source of nitrogen and phosphorus release from nutrient cycles and a cause of ecosystem eutrophication. Duckweeds, small aquatic plants, may be used to recover N and P from livestock slurry while producing high-quality protein feed. In order to assess N and P uptake efficiency and utility for fish feed, two duckweed species, Landoltia punctata and Spirodela polyrhiza, were grown in controlled climate chambers on two nutrient-rich media: diluted (1:10) cattle slurry and mechanically filtered household sewage. Treatments were in triplicate, each running in four cycles with fresh substrate (one week each). Spirodela polyrhiza exhibited the strongest growth (96 g fresh matter m−2 day−1) and highest... |

| Insect-based protein meals are in discussion as sustainable components in livestock and fish diets, with a potential to recycle wasted food materials and to replace partly feeds from arable land. Black Soldier Fly (BSF; Hermetia Illucens) is of particular interest in this context. Since insect production for animal feed appears as an additional trophic level in the food chain, it should either base on substrates, which are not directly edible for livestock and fish, or significantly improve feed efficiency or product quality to justify its application. Feed efficiency and product quality after replacing conventional protein sources by BSF meal were therefore tested in recent experiments with layers, broilers and trout. In a layer experiment, respectively... |
