    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Small-scale fisheries; tropical coastal seascape; nearshore-offshore linkages; coastal ecosystems; fish catch landings; communities; adaptation; climate change; fishing overfishing; Marine Ecotoxicology; marin ekotoxikologi;

    Abstract : Coastal habitats like mangroves, seagrass meadows, coral reefs, and adjacent offshore waters constitute an important part of the tropical coastal seascape. They provide conducive environmental conditions for fish and other marine animals, which serve as food and income for coastal communities around the world. READ MORE

  5. 3. Brewer’s yeast as a protein source in the diet of tilapia (Oreochromis niloticus) and freshwater prawns (Macrobrachium rosenbergii) reared in a clear water or biofloc environment

    Author : Huu Yen Nhi Nguyen; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis investigated the effects of dietary protein replacement of fishmeal or soybean meal with spent brewer’s yeast (SBY) in farmed tilapia and giant freshwater prawns. The effect of rearing tilapia and prawn in two different rearing systems, clear water recirculating aquaculture system (CW-RAS) and biofloc recirculating aquaculture system (Bio-RAS), were also investigated.

  6. 4. Genetic structure of natural populations : aspects of the association between genetical and morphological variability patterns

    Author : Ulf Lagercrantz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; populationsgenetik; Population Genetics;

    Abstract : Most species comprise a number of more or less reproductively isolated subpopulations. These subpopulations may exhibit striking differences in morphology and ecology, and on the basis of those differences they are often given the rank of subspecies, race, stock, variety, etc. READ MORE

  7. 5. Colonised Coasts : Aquaculture and Emergy Flows in the World System: Cases from Sri Lanka and the Philippines

    Author : Daniel A. Bergquist; Lennart Strömquist; Clas Lindberg; Torbjörn Rydberg; Aida Aragao-Lagergren; Örjan Sjöberg; Uppsala universitet; []
