  1. 1. Development of osmo- and appetite regulation during transfer of smolt from freshwater to increasing salinities

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Jonna Hellesten; [2023-01-26]
    Keywords : ;

    Abstract : Atlantic salmon (Salmo salar) is common in Scandinavian aquaculture and must be transferred from freshwater to seawater to grow properly. Despite being assessed as ready smolts, meaning they have gone through the physiological changes to prepare for SW transfer, the transfer result in a mortality rate of around 13-19%, and significant appetite- and growth reductions.

  2. 2. Parentage Assignment using genetic markers in the common carp (Cyprinus carpio)

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

    Author : Sven Kristian Feddersen; [2023]
    Keywords : single nucleotide polymorphism; Parentage Assignment; aquaculture; genetic markers;

    Abstract : This study investigated the effect of varying single nucleotide polymorphisms (SNPs) marker density, error threshold selection, and different SNP selection strategies on parentage assignment accuracy in carp populations. Using a marker set of 15,615 SNPs, we found a positive correlation between the quantity of SNP markers and the accuracy of parentage assignments, consistent with existing literature. READ MORE

  3. 3. Carbon Accounting and SeaweedOffsets : An overview of some current carbon accounting methodologiesand the emerging sector of seaweed carbon offsets

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Keywords : carbon accounting; carbon offsets; carbon credits; blue carbon; seaweed offsets; climate mitigation; sustainability; klimatkompensering; klimatberäking; begränsning av klimatförändringar; alger; tång; hållbarhet;

    Abstract : As the anthropogenic emissions of greenhouse gases (GHGs) have increased and received moreattention, the need for climate mitigation solutions has become more urgent. Today, several methodologies for carbon accounting exists, as well as the possibility to offset emissions by buying carbon offsets. READ MORE

  4. 4. Evaluation of novel climate-friendly feed for Nile tilapia in Tanzania

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

    Author : Vilma Johansson; [2023]
    Keywords : Black soldier fly; novel fish feed; circular aquaculture; sub-Sahara aquaculture; greenhouse gas emissions; LCA; Nile tilapia;

    Abstract : Tanzania is a country located in sub-Sahara Africa by the Indian Ocean. Tanzania's aquaculture sector is small but has the potential to grow. As the population grows, so does the demand for food. Nile tilapia is the most cultured fish in Tanzania due to its hardiness, fast growth and tolerance to many environmental conditions. READ MORE

  5. 5. Mussel farming along the south-Swedish coasts - a possible solution to eutrophication?

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : David Trulsson; [2023]
    Keywords : Mussel farming; Aquaculture; Spatial suitability analysis; Eutrophication; Baltic Sea; Biology and Life Sciences; Earth and Environmental Sciences;

    Abstract : The concept of mussel farming as a mitigator to nutrient pollution is steadily spreading. The southernmost part of Sweden borders the Baltic Sea where the water quality differs between the costs, however, all are affected by eutrophication. READ MORE
