  1. 6. Aquaponic systems : Potentials on a northern latitude

    University essay from Mittuniversitetet/Avdelningen för ekoteknik och hållbart byggande

    Author : David Carlsson; [2013]
    Keywords : Aquaponic; Aquaculture; Growbed; Biodiversity; Trout growth; Fish tank; System analysis; Closed loop;

    Abstract : Aquaponics is a food production method that combines hydroponic and aquaculture to form a system that, through symbiosis, re-circulates all the water and nutrients – and thereby negates any discharge of eutrophied or contaminated residuals – in order to grow terrestrial plants and aquatic life. To study the possibilities of aquaponics at northern latitude, a small scale aquaponic system was constructed in Jämtland, a county in the Mid Sweden region (latitude 63°) and studied while running over a nine month period, August 2012 to April 2013.

  2. 7. Tissue distribution of Peroxisome proliferator-activated receptors in salmon fish (Salmo salar L.)

    University essay from SLU/Dept. of Food Science

    Author : Carlota Gimeno Zafón; [2013]
    Keywords : PPAR; Atlantic salmon; fatty acid; PCR; ; qPCR; ; RT-PCR;

    Abstract : Peroxisome Proliferator-activated Receptors (PPARs) are ligand-inducible transcription factors, that can be activated by both dietary fatty acids and their metabolic derivates in the body, as by eicosanoids, hypolipidemic agents or antidiabetic drugs. To date three PPAR isotypes have been identified in mammals, birds, and amphibians, termed PPARα, PPARγ, and PPARβ/δ. READ MORE

  3. 8. The effect of different starch levels on oxygen consumption and nitrogen excretion of Eurasian perch (Perca fluviatilis)

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Rouzbeh Keihani; [2013]
    Keywords : Starch; Oxygen consumption; Nitrogen excretion; Eurasian perch Perca fluviatilis ; Respirometry;

    Abstract : Aquaculture is one of the fastest-growing and valuable industries nowadays. Because fish meal and fish oil are the major components of fish diets, there is growing concern that the rapid growth of this industry will lead to either fish meal scarcity or the depletion of marine fish population.

  4. 9. Eastern oyster aquaculture : estuarine remediation via site suitability and spatially explicit carrying capacity modeling in Virginia’s Chesapeake Bay

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Daniel Taylor; [2013]
    Keywords : eutrophication; oyster; aquaculture; physical geography and ecosystem analysis; GIS; shellfish; MCE; Chesapeake Bay; environmental modeling; Earth and Environmental Sciences;

    Abstract : Scientific summaryEstuarine eutrophication, the systemic limitation of dissolved oxygen in a body of water, has been increasingly monitored and scrutinized as an environmental concern needing acute and long term remediation efforts. The driving factors of eutrophication are largely attributed to anthropogenic sources within the watershed, sources that are products of modern civilization. READ MORE
