Operational management of sustainable fish farming

鱼类养殖是加拿大农村社区的重要经济活动，2015年产量约为15.1万吨，创收8.77亿美元，Cooke Aquarium是北美最大的国内鱼类养殖公司。尽管养鱼在提供海产品和就业机会方面有好处，但也存在环境管理问题，由DFO和各省监管。食物和粪便的废物管理是一个重要的课题，传统上通过检查笼子周围的区域来进行管理。然而，一个改进的管理办法将包括更广泛的生态系统。达尔豪西的两名科学家（格兰特和菲尔盖拉）将与库克·阿奎拉尼合作，帮助将研究成果转化为最佳实践。比较水产养殖法规在加拿大和广泛的将有助于库克更有效地遵守。除了政府监管机构，还有生态标签品牌也要求农场遵守。我们将帮助提高这些标准的效力。我们还将进一步开发计算机模型和软件，以更好地了解农场使用的兽药的途径，以及农场废物（例如未食用的食物）的命运。这包括对大面积的沉积物进行实地取样，以检验我们的发现。总的来说，这些结果将改善沿海生态系统中鱼类养殖的“适应性”，并提高可持续性。

Fish farming is an important economic activity in rural communities in Canada, producing approximately 151 thousand tonnes and generating $877 million in 2015, and Cooke Aquaculture is the largest domestic fish farming company in North America. Despite the benefits of fish farming in providing seafood and jobs, there are environmental management issues, regulated by DFO and the provinces. Waste management of food and feces is an important topic, and has traditionally been regulated by examining the area around the cages. However, an improved management approach would include the wider ecosystem. Working with Cooke Aquaculture, two scientists at Dalhousie (Grant and Filgueira) will help translate research results into best practices. Comparison of aquaculture regulations in Canada and broad will assist Cooke with more efficient compliance. In addition to government regulators there are ecolabeling brands that also require farm compliance. We will help improve the efficacy of those standards. We will also further develop computer models and software to better understand the pathways of veterinary medicine used on the farm, as well as the fate of farm waste (e.g uneaten food). This involves field sampling of sediments sampled over wide areas to test our findings. Collectively, these results will improve the 'fit' of fish farming in coastal ecosystems, and lead to increased sustainability.
