Aquaponic systems are engineered ecosystems combining aquaculture and plant production. Nutrient rich water is continuously circulating through the system from aquaculture tanks. A biofilter with nitrifying bacteria breaks down fish metabolism ammonia into nitrite and nitrate, which plants and makes the aquaculture wastewater into valued organic fertiliser for the plants, contenting essential macro and micro elements. At the same time, plants are cleaning the water by absorbing ammonia from the fish tanks before it reaches dangerous levels for the aquatic animals. In principle, the only external input is energy, mainly in the form of light and heat, but fish food is also commonly provided. Growing fish food is potentially feasible in a closed loop system, hence aquaponic systems can possibly be an important source of proteins and other important nutrition when, for example, colonising other planets in the future. Fully autonomous aquaponic systems are currently not available. This work aims at minimising manual labour related to cleaning pipes for water transport. The cleaning process must be friendly to both plants and aquatic animals. Hence, in this work, pure mechanical cleaning is adopted. A novel belt-driven continuum robot capable of travelling through small/medium diameter pipes and manoeuvring branches and bends, is designed and tested. The robot is modular and can be extended with different cleaning modules through an interface providing CAN-bus network and electric power. The flexible continuum modules of the robot are characterised. Experimental results demonstrate that the robot is able to travel through pipes of diameter 50 mm to 75 mm, and also capable of handling T-branches of up to 90 degrees.

Climate change may result in increased root system stresses in strawberry cultivation, requiring cultivars with root and crown-related resistance and resiliency traits. Approaches to widen the genetic basis and improve tools for the incorporation of novel variation are relevant to plant breeding for changing climate. The pre-breeding project NORDFRUIT is a Nordic public-private-partnership project that aims to introduce novel genetic variation from new sources, support the use of existing genetic resources adapted to Nordic and Baltic cultivation conditions, and develop efficient tools to speed up germplasm evaluation in breeding programs for climate adaptation. Pre-evaluated genotypes of Fragaria chiloensis or Fragaria virginiana were used as parents in interspecific (species hybridization) crosses, re-creating the garden strawberry hybrid species, F. ×ananassa. The created F1 hybrid seedlings were propagated by runners for replicated phenotyping trials. A greenhouse assay to test root-shoot biomass partition, growth vigour and Phytophthora cactorum resistance in these small plants was scaled up from an earlier assay based on nutrient film technology (NFT). The observed variation in disease symptom appearance, root-shoot ratio, and root proliferation indicated promising traits in the strawberry hybrid material, to be exploited further in genomic studies and to develop genome-assisted resistance breeding. The on-going work also includes field testing of the same hybrid material to evaluate winter hardiness, powdery mildew incidence, and fruit traits.
