  1. 6. Spatial and temporal variations in stable isotope signatures (δ13C and δ15N) of the gammarids and the common carp in the southern coast of the Caspian Sea

    University essay from SLU/Dept. Of Aquatic Resources

    Author : Nazila Hajizadeh Koupayeh; [2020]
    Keywords : carbon stable isotope; Caspian sea; Cyprinus carpio; food webs; Gammarus aequicauda; nitrogen stable isotope; Pontogammarus maeoticus;

    Abstract : Despite the growing body of research on the use of stable isotope analysis in food web studies, spatial and temporal variations in stable isotope ratios of coastal communities are still poorly understood. The aim of my study is to explore how carbon and nitrogen stable isotopes of selected benthic communities vary spatially and temporally across the south of Caspian Sea. READ MORE

  2. 7. Design of fish feeding mechanism for Recirculation Aquaculture System (RAS)

    Keywords : Aquaculture; Hopper; Discrete elements; Mechanical design; Vattenbruk; Hopper; Diskreta element; Mekanisk design;

    Abstract : Fish farming or Aquaculture is a growing food-producing industry to culture the fish in artificially constructed tanks. A large number of fishes are reared in tanks for 100-150 days and produce food for the population. READ MORE

  3. 8. Genetic diversity status and associations with sperm quality characteristics in farmed Arctic charr (Salvelinus alpinus L.) across Sweden

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Anam Anjum; [2020]
    Keywords : Arctic charr; dd-RADseq; genetic diversity; GWAS; reproductive success;

    Abstract : The national breeding programme of Arctic charr (Salvelinus alpinus L.) has been of fundamental importance for the expansion of Arctic charr farming across Sweden.

  4. 9. Algae cultivations in Kenya- a sustainable solution? : An assessment and investigation over deepwater cultivation in Shimoni, Southern Kenya

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik; KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Greta Gustafsson; Amanda Sivard; [2020]
    Keywords : Macro algaes; aquaculture; deep-water techniques; Kenya; Makroalger; vattenbruk; djupt vatten; Kenya;

    Abstract : With a strong demand for aquatic products, seaweed is a promising application in a wide range of areas, such as food, medicine and energy. Kenya is seen as a country with great potential of expanding its seaweed industry, and by inspiration from the widespread production of algaes at Zanzibar, improvements and adaptations can be made to fit Kenya.

  5. 10. Life cycle assessment of DHA produced by microalgae using food waste : Assessing global warming, fossil energy use and effects on biodiversity

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Louise Bartek; [2020]
    Keywords : Life cycle assessment LCA ; docosahexaenoic acid DHA ; biodiversity loss; volatile fatty acids VFA ; global warming; sustainable development; Livscykelanalys LCA ; dokosahexaensyra DHA ; biodiversitet; flyktiga fettsyror VFA ; global uppvärmning; hållbar utveckling;

    Abstract : Biodiversity is a key component for life on Earth since it contributes to clean water, fresh air and food security. Today, fatty fish farmed in aquaculture is the main Omega 3 source consumed by humans, including the essential fatty acid docosahexaenoic acid (DHA). DHA origin from plants and accumulate in fish via the marine food web. READ MORE
