| Integrated Multi-Trophic Aquaculture takes advantage of the mutualism between some detritivorous fish and phytoplankton. The fish recycle nutrients by consuming live (and dead) algae and provide the inorganic carbon to fuel the growth of live algae. In the meanwhile, algae purify the water and generate the oxygen required by fishes. Such mechanism stabilizes the functioning of an artificially recycling ecosystem, as exemplified by combining the euryhaline tilapia Sarotherodon melanotheron heudelotii and the unicellular alga Chlorella sp. Feed addition in this ecosystem results in faster fish growth but also in an increase in phytoplankton biomass, which must be limited. In the prototype described here, the algal population control is exerted by herbivorous... |

| Breeding varieties adapted to various organic farming conditions is one solution, among others, to increase yields and improve organic winter bread wheat quality. From 2004 to 2011, INRA winter wheat breeders have conducted variety trials in three contrasting agro-climatic regions across north-west France to test the relative response of 25 to 30 diversified genotypes when cultivated in low input (FI) and organic (AB) conditions. The comparison of 17 paired management trials showed the relevance of low input conditions to identify genotypes adapted to organic farming conditions for yield and protein content. Such a selection environment is useful also to screen “GPD+” (positive Grain Protein Deviation) genotypes with better nutrient use efficiency. In... |
