Operational management of sustainable fish farming

鱼类养殖是加拿大农村社区的一项重要经济活动，2015年产量约为15.1万吨，创收8.77亿美元，库克水产养殖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方面有好处，但仍存在环境管理问题，由渔业部和各省监管。食物和粪便的废物管理是一个重要的话题，传统上是通过检查笼子周围的区域来管理的。但是，改进的管理办法将包括更广泛的生态系统。Dalhousie的两位科学家（Grant和Filgueira）将与Cooke水产养殖公司合作，帮助将研究成果转化为最佳实践。比较加拿大和其他国家的水产养殖法规将有助于库克更有效地遵守法规。除了政府监管机构，生态标签品牌也要求农场遵守规定。我们将帮助提高这些标准的有效性。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。这包括在大范围内对沉积物进行实地取样，以检验我们的发现。总的来说，这些结果将改善鱼类养殖在沿海生态系统中的“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.
