  1. 1. Between roving and stewarding marine environments : Practices and development of Swedish coastal fisheries in the Baltic Sea

    Författare :Emma Björkvik; Wijnand Boonstra; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Stewardship; fishing practices; sustainable development; coastal fisheries; Baltic Sea; fishers’ behavior; Sustainability Science; vetenskap om hållbar utveckling;

    Sammanfattning : Whether and how capture fisheries can increase catches and be sustainable at the same time i sa pertinent question for fisheries in the Global North. To ensure sustainable development of these fisheries, it is essential for fisheries management to pay attention to fishers’ behavior. LÄS MER

  3. 2. The conflict between Grey seals (Halichoerus grypus) and the Baltic coastal fisheries : new methods for the assessment and reduction of catch losses and gear damage

    Författare :Arne Fjälling; Mats Amundin; Sverre Sjölander; Anders Fernö; Linköpings universitet; []
    Nyckelord :Ecology; Grey seals; Baltic coastal fisheries; Ekologi; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : There is a problematic interaction going on between grey seals and the small scale coastal fisheries in the Baltic. A large number of seals are by-caught and drowned each year, and the viability of the fishery is threatened by catch losses caused by the seals. LÄS MER

  4. 3. Seals and fisheries: a study of the conflict and some possible solutions

    Författare :Sara Königson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; seals and fisheries; grey seal; coastal fisheries; harbour seal; seal-safe fishing gear;

    Sammanfattning : Interaction between seals and fisheries along the Swedish coast has serious environmental and economic consequences. This thesis describes the conflict as it affects four different small-scale coastal fisheries; the eel fisheries on the west coast, the herring fisheries and salmon fisheries in the northern Baltic and the cod fisheries in the central Baltic.

  5. 4. Spatial Modelling of Coastal Fish – Methods and Applications

    Författare :Göran Sundblad; Ulf Bergström; Alfred Sandström; Peter Eklöv; Christian Möllmann; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; habitat; niche; species distribution modelling; juvenile; fish; larvae; spawning; Marine ecology; Marin ekologi; NATURAL SCIENCES; NATURVETENSKAP; Freshwater ecology; Limnisk ekologi; Biology; Biologi; Biology with specialization in Limnology; Biologi med inriktning mot limnologi; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology; Limnologi; Limnology;

    Sammanfattning : Environmental factors influence species and habitats on multiple scales creating a mosaic of distribution patterns. Studying factors shaping these patterns are central to our understanding of population dynamics and ultimately ecosystem functioning. LÄS MER

  7. 5. Eel migration - results from tagging studies with relevance to management

    Författare :Niklas B. Sjöberg; Sture Hansson; Håkan Wickström; Erik Petersson; Alan Walker; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Anguilla anguilla; Migration; Stocking; Marking; Anguillicola crassus; Data storage tags; Carlin tagging; Strontium; Survival analysis; Dormancy; Lake Mälaren; Baltic Sea; Atlantic Ocean; Sargasso Sea; Marine Ecology; marin ekologi;

    Sammanfattning : In response to the drastic decline of the European eel (Anguilla anguilla (L.)) fisheries have been reduced and elvers are stocked in areas where natural abundances are low. LÄS MER
