  1. 1. Do potentially seal-safe pingers deter harbour porpoises (Phocoena phocoena) in the vicinity of gillnets and thereby reduce bycatch?

    Master-uppsats, Linköpings universitet/Biologi

    Författare :Simon Björklund Aksoy; [2020]
    Nyckelord :Acoustic Deterrent Device; Banana pinger; Bycatch; Commercial fishery; C-POD; Dinner-bells; Future Oceans pinger; Harbour porpoise;

    Sammanfattning : Incidental bycatch in gillnets is a substantial threat to small cetaceans. Using Acoustic Deterrent Devices, “pingers”, have successfully reduced bycatch of harbour porpoises in gillnets. LÄS MER

  2. 2. Analysing the seal-fishery conflict in the Baltic Sea and exploring new ways of looking at marine mammal movement data

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Ornella Jogi; [2017]
    Nyckelord :Halichoerus grypus; Phoca hispida botnica; seal-fishery conflict; human-wildlife conflict; integrated step selection analysis;

    Sammanfattning : A comprehensive analysis of the available data reveals that there is currently not enough information for making informed management decisions regarding the seal-fishery conflict in the Baltic Sea. Knowledge of hidden and visual damages is limited, which means that the actual cost to the fishing industry from damages is not known. LÄS MER

  3. 3. ”At least they can´t buy the sun quotas” - A case study on the part played by Individual Tradable fishing Quotas in the articulation of identity narratives in Råå, Sweden

    Master-uppsats, Lunds universitet/Humanekologi

    Författare :Jill Jarnsäter; [2017]
    Nyckelord :Swedish fishery; Individual Transferable Quotas; market-based system; identity; Råå; marketization process; social disruption; Social Sciences;

    Sammanfattning : In 2009, an extensive reform of the Swedish fisheries was implemented. After several decades of regulation based on the principle of fish resource as common property, fish was put in a system of Individual Transferable Quotas (ITQs) and released from the state and given to vessel owners.

  4. 4. Attack behavior and presence of grey seals around pots : a search for seal-safe cod-pots in the Baltic sea

    Master-uppsats, SLU/Dept. Of Aquatic Resources

    Författare :Jasmine Stavenow; [2016]
    Nyckelord :grey seal; Halichoerus grypus; seal behavior; seal attacks; seal presence; sealsafe; seals-fishery conflict; seals and fishery; fishing gear; cod-pots; sustainable fishing; Baltic sea; coastal fishery;

    Sammanfattning : The seals and the fishery are forced to share the role as top-predators in the Baltic waters since they both depend on the same fish stocks, which leads to an unavoidable competition. Seals are raiding traps, leading not only to costly damaged fishing gears and loss in fish catch but also to the seals themselves getting caught and drowned in the gears as by-catch. LÄS MER

  5. 5. Self-Governance in the Commons - A study of social control in Swedish recreational lobster fisheries

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Vera Telemo; [2015]
    Nyckelord :Commons self-governance lobster; Earth and Environmental Sciences;

    Sammanfattning : Most of the natural resources we rely on for our existence on this planet could in one way or another be a subject to overexploitation through tragedy of the commons. Tragedy of the commons occurs when rational individuals all acting in their own self-interest creates a situation that is suboptimal for everyone involved (Hardin, 1968). LÄS MER
