1. 1. Marina kolonilotter - en hållbarhetsnisch i ett sociotekniskt landskap: En kvalitativ studie av marina kolonilotters potentiella roll i omställningen mot hållbar livsmedelsproduktion och samhällen

   Kandidat-uppsats, Göteborgs universitet/Institutionen för globala studier

   Författare :Linnéa Andersson; [2023-10-18]
   Nyckelord :Marina kolonilotter; Havskoloni; Blue community gardens; Regenerative aquaculture; Small scale ocean farming; Transition theory; Socio-technical transitions; Multi level perspekctive;

   Sammanfattning : This study aims to contribute knowledge and understanding regarding the role of political governance in facilitating grassroots initiatives that hold potential for advancing sustainable development. Specifically, the research investigates the potential role of Blue/marine community gardens in the transition towards sustainable societies and food production. LÄS MER

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

   Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Författare :Jonna Hellesten; [2023-01-26]
   Nyckelord :;

   Sammanfattning : 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.

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

   Master-uppsats, SLU/Dept. of Animal Breeding and Genetics

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

   Sammanfattning : 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. LÄS MER

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

   Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

   Författare :Alice Rudberg; [2023]
   Nyckelord :carbon accounting; carbon offsets; carbon credits; blue carbon; seaweed offsets; climate mitigation; sustainability; klimatkompensering; klimatberäking; begränsning av klimatförändringar; alger; tång; hållbarhet;

   Sammanfattning : 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. LÄS MER

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

   Master-uppsats, SLU/Dept. of Animal Nutrition and Management

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

   Sammanfattning : 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. LÄS MER
