Photo-induced Advanced Oxidation Processes (AOPs) using H2O2 or S2O82− as radical precursors were assessed for the abatement of six different contaminants of emerging concern (CECs). In order to increase the efficiency of these AOPs at a wider pH range, the catechol organic functional compound was studied as a potential assistant in photo-driven iron-based processes. Different salinity regimes were also studied (in terms of Cl− concentration), namely low salt water (1 g·L−1) or a salt–water (30 g·L−1) matrix. Results obtained revealed that the presence of catechol could efficiently assist the photo-Fenton system and partly promote the photo-induced S2O82− system, which was highly dependent on salinity. Regarding the behavior of individual CECs, the photo-Fenton reaction was able to enhance the degradation of all six CECs, meanwhile the S2O82−-based process showed a moderate enhancement for acetaminophen, amoxicillin or clofibric acid. Finally, a response-surface methodology was employed to determine the effect of pH and catechol concentration on the different photo-driven processes. Catechol was removed during the degradation process. According to the results obtained, the presence of catechol in organic macromolecules can bring some advantages in water treatment for either freshwater (wastewater) or seawater (maritime or aquaculture industry).

Abstract This article investigates, using a sociology of profession approach, why veterinarians and aqua medicine biologists share jurisdiction in fish health in Norway. I use a five-actor framework to highlight key events in the development of the Norwegian model for inter-professional and cross-sectoral collaboration in fish health. Veterinarians were initially the only profession involved in fish health. However, in the late 1980s, the Norwegian aquaculture industry suffered great losses due to significant disease outbreaks. Lack of scientific knowledge about the disease causing the outbreaks, Hitra disease, and lack of veterinary capacity to cope with the problem resulted in a situation in which veterinarians continued, as an early response to the disease, to use antibiotic-based therapies. The marine science milieu, with support from the aquaculture industry, instituted a vaccine solution to the endemic Hitra disease in 1987. This scientific breakthrough had major impacts on combatting fish diseases and on the further development of vaccines. New vaccine solutions for other diseases, such as furunculosis, were developed by international and multidisciplinary collaboration. Over a 7-year period, the use of antibiotic-based therapy was dramatically reduced. The control of fish diseases is aquaculture’s X factor, and without these vaccine solutions and regulation regimes, the story of Norwegian aquaculture could have been different. The successful development of the Hitra disease vaccine enabled the marine science milieu at the University of Bergen and the University of Tromsø to establish a new programme of education for aqua medicine biologists based on their own scientific knowledge base. However, their struggle for shared jurisdiction, including the right to prescribe veterinary medicine, lasted nearly 20 years. In 2005, veterinary legislation was amended, and in addition to medical doctors, dentists and veterinarians, aqua medicine biologists, as the fourth profession in Norway, gained the right to prescribe medical products. I argue that the experience in Norway, where professionals from two different sectors share jurisdiction and work side by side in fish health, is worth examining as a model for organizing inter-professional and cross-sectoral collaboration.

Abstract Aquaculture is currently one of the most rapidly growing food production industries in the world. The increasing global importance for this industry stems primarily from the fact that it is reducing the gap between the supply and demand for fish products. Commercial aquaculture contributes significantly to the economies of many countries since high-value fish species are a major source of foreign exchange. This review looks at the aquaculture industry, the issues raised by the production of fish through aquaculture for food security, the sustainability of the practice to agriculture, what the future holds for the industry in the next 10-20 years, and why there is a need to have available analytical procedures to regulate the safe use of chemicals and veterinary drugs in aquaculture.

Commercial salmon farming in the Maritimes shows potential as a source of rural employment, growth, and foreign exchange. Canada lags behind most advanced countries in developing its aquaculture industry; Atlantic salmon (Salmo salar) might be one species in which Canada has a comparative advantage and in which Canada's late start might be overcome. This paper evaluates sea pen salmon culture by a number of criteria, including financial feasibility, and concludes that salmon farming can be profitable, contribute to growth, absorb labour, and earn foreign exchange. A final section explores policy options available to governments and to private sector producers.
