2. 1. Coral Reef Habitats and Fish Connectivity : Implications for coastal management and fishery

   Author : Tove Lund Jörgensen; Michael Tedengren; Nick Graham; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; anthropogenic disturbance; coral reef habitat; fish community; coastal ecosystems; conservation management; spatial ecology; seascape perspective; holistic approach; marin ekotoxikologi; Marine Ecotoxicology;

   Abstract : Coral reefs have one of the highest levels of biodiversity of all ecosystems in the world and are important for both human livelihood and food security throughout many tropical countries. However, due to increased anthropogenic pressure on marine ecosystems, especially during the last couple of decades, coral reefs have become critically over-fished, and many reefs are now in a degraded state and are facing additional future threats due to further over-exploitation, chemical pollution, sedimentation, and effects of climate change.

4. 2. Fishing the gene pool : Genetic structure, admixture and behavioural complexity in fisheries management

   Author : Kim H. Berndt; Enhet akvatisk ekologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fisheries management; Fishery stock; Stock discrimination; Genetic structure; Genetic admixture; Admixture zone; Stock substructure; Phenotypic divergence; Gadus morhua; Salmo trutta;

   Abstract : Prudent management of marine fish resources relies on separation and management of biologically meaningful groups of conspecifics, termed fishery stocks, often depicted as self-sustaining, spatiotemporally separated and demographically independent entities. Such stock discrimination has however proven challenging. READ MORE

5. 3. Essays on Natural Resource Economics

As a result, resource users do not generally accept such rules. READ MORE

6. 4. Fisheries biology of the edible crab (Cancer pagurus) in the Kattegat and the Skagerrak - implications for sustainable management

   Author : Anette Ungfors; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cancer pagurus; Swedish west coast; sexual maturity; migration; population genetics; stock structure; fishing mortality; stock abundance; management;

   Abstract : The European edible crab (Cancer pagurus) is exploited to a varying degree in its area of distribution. Landings in United Kingdom and Ireland may have peaked around year 2000, reaching 25 000 and 13 000 tonnes, respectively but have slightly decreased since. READ MORE

7. 5. Migration and quality of landlocked Atlantic salmon smolt : Implications for conservation and management

   Keywords : NATURVETENSKAP; NATURAL SCIENCES; acoustic telemetry; hatchery; life history; migration mortality; regulated rivers; Salmo salar; salmon; smolt; trout; Biology; Biologi;

   Abstract : Atlantic salmon Salmo salar has a complex life cycle, including long migrations and habitat shifts for both juveniles and adults. As such, salmon populations are vulnerable to habitat degradation and fragmentation along their migratory routes. READ MORE
