2. 1. Protein Yield and Protein Isolate Quality when applying pH-shift Processing on Cod, Haddock and Blue Whiting Fillets- Effects of Replacing Centrifugation with Filtration

   Author : Helgi Nolsøe; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; fish; cod; protein yield; pH-shift processing; haddock; centrifugation; surimi; Protein isolate; filtration; blue whiting;

   Abstract : A more sustainable fishery and a better utilization of the harvested fish raw material are currently of great importance to prevent overexploitation of our marine resources. Production of protein isolates to use for example as surimi has for many years been an important way of better utilizing low-value fish species and fish rest raw materials. READ MORE

4. 2. The role of young-of-the-year fish in lake ecosystems

   Author : Pia Romare; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hydrobiology; Rutilus rutilus; Perca fluviatilis; diet-dependent growth; density dependent growth; behavioural cascade; 0 fish behaviour; horizontal echo sounding; biomanipulation; trophic cascade; predation pressure; young-of-the-year fish; trophic interactions; marine biology; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi; Ecology; Ekologi;

   Abstract : Food chain theory is based on consumption; that is, presupposing that the only important interaction between organisms is that they actually meet in an unstructured environment and that one of them is consumed. Recently, studies, including biomanipulation projects, have indicated that trophic interactions are more complex than predicted by food chain theory. READ MORE

5. 3. Flow design for migrating fish

   Author : Elianne Lindmark; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

   Abstract : The utilization of rivers for hydropower production leads to problems for migrating fish, such as Atlantic salmon (Salmo salar) and sea trout (Salmo trutta). Both salmon and trout reproduce in fresh water, but spend their adult years at sea. To overcome man-made obstructions to and from the spawning grounds the fish needs help. READ MORE

6. 4. Novel approaches to the environments and ecosystems of the fish-tetrapod transition

   Author : Hannah Byrne; Per Ahlberg; Grzegorz Niedzwiedzki; Henning Blom; Benjamin P. Kear; Matt Friedman; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fish-tetrapod transition; synchrotron scanning; tides; coprolites; Carboniferous;

   Abstract : The fish-tetrapod transition is one of the most important evolutionary events in Earth’s history, giving rise to terrestrial vertebrates around 390 million years ago. It set the stage for a series of evolutionary events that ultimately resulted in modern-day terrestrial vertebrates including ourselves. READ MORE

7. 5. Novel FISH methods to unveil genome architecture

   Author : Ana Mota; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : The genome consists of incredibly long DNA strands that encode all the vital information for the cell to function. The DNA inclusion in the very tight nuclear space and, simultaneously, the establishment of a hierarchical organization of the chromatin that favors transcription of certain genes over others, sparked a long-lasting quest to understand the design principles that govern genome architecture.
