Providing sufficient and high-quality food for the steadily increasing global human population is one of the most pressing challenges of the 21st century. In the face of world-wide declining ocean fisheries, aquaculture provides a promising alternative: the industrial production of nutritionally valuable food of aquatic origin. Large-scale aquaculture is a comparatively recent industrial sector. Its future in Canada depends on research that leads the way to economically efficient, yet environmentally sustainable methods of production. Our team of university and governmental scientists believes that the key to achieving this goal lies in understanding and managing aquaculture facilities as a food-web that is embedded in the natural, spatially extended marine ecosystem. We will cooperate with the mussel aquaculture industry on the Magdalen Islands and conduct experimental research that applies the principles of food web and ecosystem ecology. We will explore how the flows of matter and energy across the food web can be managed in a way that results in an increased production of high-quality, harvestable shellfish. Our approach is novel in that it goes beyond examining these processes at the scale of the individual mussel but attempts to understand the process of shellfish production in an ecosystem context. We anticipate that our research will affect governmental policy and eventually translate into novel production methods in Canadian shellfish aquaculture, mediated by our governmental and industrial supporting organizations.

为稳步增长的全球人口提供充足、优质的食物是21世纪最紧迫的挑战之一。面对世界范围内海洋渔业的衰退，水产养殖提供了一个有希望的替代方案：工业化生产有营养价值的水产食品。大规模水产养殖是一个相对较新的工业部门。它在加拿大的未来取决于研究，导致经济高效，但环境可持续的生产方法。我们的大学和政府科学家团队认为，实现这一目标的关键在于理解和管理水产养殖设施，将其作为嵌入自然的、空间扩展的海洋生态系统中的食物网。我们将与马格达伦群岛的贻贝养殖业合作，应用食物网和生态系统生态学原理进行实验研究。我们将探讨如何在整个食物网的物质和能量流可以在一种方式，导致高品质的，可收获的贝类产量增加管理。我们的方法是新颖的，因为它超越了检查这些过程中的个人贻贝的规模，但试图了解贝类生产的过程中的生态系统。我们预计，我们的研究将影响政府政策，并最终转化为加拿大贝类水产养殖的新生产方法，由我们的政府和工业支持组织介导。
