    Abstract : The genetic impact of farmed fish escaping aquaculture is a highly debated issue. However, non-target species, such as cleaner fish that are used in fish farms to remove parasitic sea lice, are rarely considered. READ MORE

  4. 2. e-Learning for Environment: Improving e-Learning as a Tool for Cleaner Production Education

    Author : Carl Eneroth; Internationella miljöinstitutet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Environmental education; Cleaner production; Information technology;

    Abstract : The achievement of a sustainable society is ultimately an educational enterprise. E-learning has a role to play in this endeavour, as it permits global access to environmental education, independent of time and place,once the courses are available on the Internet. READ MORE

  6. 4. Crossing barriers: Genetic consequences of translocating wild cleaner fish for aquaculture

    Author : Ellika Faust; Göteborgs universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; conservation genetics; population genetics; aquaculture escapee; hybridisation; corkwing wrasse; lumpfish; cleaner fish translocation; sea lice; range expansion; fishery management;

    Abstract : Several species of fish show a symbiotic cleaning behaviour, where they assist other species by feeding and removing dead skin or ectoparasites. Some of these cleaner fish species are used as a low-cost parasite control in salmon aquaculture, often considered to be more environmentally friendly than other delousing methods. READ MORE

  7. 5. Preventive Environmental Strategies in Eastern European Industry: An analysis of donor support for cleaner production
