1. Lipid Oxidation in Fillets of Herring (Clupea harengus) during Processing and Storage
Sammanfattning : The influence of storage and processing on the development of lipid oxidation in herring fillets was investigated and related to their composition of lipids, catalysts and antioxidants. The progress of oxidation was monitored as antioxidant loss and as the development of primary, secondary and tertiary lipid oxidation products. LÄS MER
2. Antioxidative Properties of Herring (Clupea harengus) Press Juice in Food, In Vitro and In Vivo Model Systems
Sammanfattning : Some species like herring (Clupea harengus) are currently under-utilized due to their small size, dark colour and susceptibility to lipid oxidation. Our hypothesis has been that the high susceptibility of herring to oxidation makes it well equipped with natural antioxidants, both fat and water soluble ones. LÄS MER
3. Feeding ecology of Baltic Sea herring (Clupea harengus L.) : field and model studies of a dominant zooplanktivor

4. Zooplankton growth and trophic linkages : Implications for fish feeding conditions in the Baltic Sea
Sammanfattning : The aim of this Thesis was to improve our understanding and assessment of feeding conditions for zooplanktivorous fish in the Baltic Sea.We investigated (papers I, II) the usefulness of biochemical proxies for assessments of growth and metabolic rates in the dominant Baltic copepod Acartia bifilosa.

5. Dynamics of astaxanthin, tocopherol (Vitamin E) and thiamine (Vitamin B1) in the Baltic Sea ecosystem : Bottom-up effects in an aquatic food web
Sammanfattning : The thesis combines laboratory experiments and field expeditions to study production, transfer and consumption of non-enzymatic antioxidants and thiamine in an aquatic food web. In particular, I (1) documented spatial and seasonal variation of tocopherols and carotenoids in the Baltic Sea pelagic food web, and (2) examined the effects of abiotic and biotic factors on tocopherol, carotenoid and thiamine concentrations in phytoplankton, zooplankton and fish.
