  1. 1. The hydrodynamic impacts of Estuarine Oyster reefs, and the application of drone technology to this study

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Oskar Evert Johansson; [2021]
    Keywords : Geography; Geographical Information Systems; GIS; Physical Geography; Oyster Reef; Drone; UAV; Hydrodynamics; Earth and Environmental Sciences;

    Abstract : The impacts of climate change are being seen within the estuarine environment through erosion and shoreline retreat, associated with sea-level rise and changes in storm activity. Restoration oyster reefs have been identified as a working-with-nature strategy to protect and restore these shoreline environments, stabilising sediment, and reducing erosion. READ MORE

  3. 2. Development of northern pike (Esox lucius) populations in the Baltic Sea, and potential effects of grey seal (Halichoerus grypus) predation

    University essay from SLU/Dept. Of Aquatic Resources

    Author : Rebecka Svensson; [2021]
    Keywords : diet analysis; ; marine mammals; predator-prey; socio-economic; sport fishing; recreational fisheries;

    Abstract : Worldwide, marine mammal populations are increasing after considerable efforts to turn the downward trends caused by hunting, accidental mortality and pollution. The ecosystem effects from the increases of these top predators may be pronounced, but are in most cases poorly known. READ MORE

  4. 3. Increased body growth rates of northern pike (Esox lucius) in the Baltic Sea : importance of size-selective mortality and warming waters

    University essay from SLU/Dept. Of Aquatic Resources

    Author : Terese Berggren; [2019]
    Keywords : Northern pike; Esox lucius; Back-calculated length; Body growth; Size-selective mortality; Warming waters; Baltic Sea;

    Abstract : The northern pike, Esox lucius Linnaeus (1758), is a highly valuable species in recreational fishing, and plays a vital role as a keystone predator in the structuring of fish communities in temperate lakes and brackish waters. Ma-jor declines of pike in the Baltic Sea have been recorded, particular of larger pikes, which may have cascading effects on abundances of lower ecosys-tem compartments. READ MORE

    Abstract : In the shadow of commercial fishing fleets, recreational fishers are a lesser known but still substantial group exerting pressure on the world’s aquatic ecosystems and its fish stocks. Enthusiastic angler participation, high catch rates, catch selectivity and harmful fishing techniques characteristic of recreational fishers can have detrimental impacts on the aquatic environment.
