Currently, one of the most pressing issues facing humankind is where we will obtain high quality, environmentally sustainable sources of protein for a burgeoning population that is predicted to reach 9 billion people within the next 50 years. While cage aquaculture holds great promise in helping to meet these needs, one impediment to the growth of the industry is the uncertainty surrounding potential detrimental effects of the practice on local ecosystem biodiversity, structure and function. Currently, regulatory frameworks address the effects of aquaculture on nutrient levels and invertebrate diversity and abundance. However, research has shown that the greatest public concern surrounding aquaculture operations is the potential effects on local wild fish communities. Interestingly, recent research has shown that while there are localized detrimental effects of cage aquacultural practices on nutrient and invertebrate populations, there also exist potentially beneficial effects on local fish populations. The goal of this NSERC CRD research program is to use recent advances in biotracer technology to develop tools to quantify effects of cage aquaculture on local fish populations in Georgian Bay, Lake Huron. By deploying these tools to a number of sites that vary in local environmental conditions and management practices, the results of this program will help to both inform fish farmers as to best practices in cage placement and feeding, as well as to provide a basis for a regulatory framework that incorporates the effects of aquaculture on local fish communities. In pursuing this avenue of research, the Ontario aquaculture industry will position itself to sustainably grow to meet the ever growing needs of a growing and protein demanding population in Ontario, Canada and abroad. ********

目前，人类面临的最紧迫的问题之一是，我们将为新兴的人群获得高质量，环境可持续的蛋白质来源，预计在未来50年内将达到90亿人口。 尽管Cage水产养殖在帮助满足这些需求方面有着巨大的希望，但对行业发展的障碍是围绕该实践对当地生态系统生物多样性，结构和功能的潜在有害影响的不确定性。 当前，监管框架涉及水产养殖对养分水平和无脊椎动物多样性和丰度的影响。 但是，研究表明，围绕水产养殖业务的最大公众关注是对当地野生鱼类社区的潜在影响。 有趣的是，最近的研究表明，尽管笼子水产养殖实践对养分和无脊椎动物种群存在局部有害影响，但对当地鱼类种群也存在潜在的有益作用。 该NSERC CRD研究计划的目的是利用生物敏捷技术的最新进展来开发工具来量化笼子水产养殖对休伦湖乔治亚湾当地鱼类种群的影响。 通过将这些工具部署到许多在当地环境条件和管理实践中有所不同的地点，该计划的结果将有助于将养鱼者告知笼子放置和喂养方面的最佳实践，并为融合水产养殖对当地鱼类社区的影响的监管框架提供基础。 在追求这一研究途径时，安大略省水产养殖行业将自己定位，以满足安大略省，加拿大和国外需求不断增长和蛋白质需求的不断增长和蛋白质的需求。 ********
