In Canada, aquaculture is an $840 million industry that has extensive operations in British Columbia (i.e., $426 million) and New Brunswick (i.e., $250 million) while Ontario accounts for less than $20 million (see Aquaculture.ca/economicbenefits, 2016). Rainbow Trout is the major fish species produced through commercial aquaculture and generates $18 million in Ontario, despite its status as non-native. However, Ontario possesses many assets for new aquaculture development such as proximity to the world's largest freshwater areas (the Great lakes), access to national and international markets, and the availability of research expertise, equipment, and infrastructure (Moccia, Naylor, & Reid, 1997). One native fish species that can be reared intensively and extensively is the Lake Whitefish (Lazenby, Kerr, & Hooper, 2001). Herbert Fisheries is a commercial fisheries company that have noted over recent years a decrease in landings, particularly Lake Whitefish, which was first pointed out by the Great Lakes Fisheries Commission (2005). The demand for Lake Whitefish been corroborated by fishery operators throughout the Great Lakes (see Kunninen, 2003). In order to supply this demand, cage culture of Lake Whitefish is the proposed solution. However, Research partners are needed that will be able to grow the fish from eggs to fingerlings in land-based hatcheries and to market size (i.e., 500 grams) at cage culture sites. Collège Boréal is a postsecondary institution that possesses the expertise and equipment needed to incubate the eggs and raise the Lake Whitefish fry until they reach fingerling status. Then, Open Water Systems Limited, a company that developed a new submersible cage prototype, is willing to provide their cage to raise the Lake Whitefish until market-size, while the college's research team continues to collect and analyse data related to the growing of Lake Whitefish in cage culture according to the Cage Culture Guidelines of the Ministry of Natural Resources and Forestry. Together, the partnering of the college, two private companies, and the MNRF seek to study the feasibility of raising Lake Whitefish from egg to adults for commercial purposes.

在加拿大，水产养殖是一个价值8.4亿美元的行业，在不列颠哥伦比亚省（即4.26亿美元）和新不伦瑞克省（即2.5亿美元）拥有广泛的业务，而安大略省则占2000万加元（请参阅Aquaculture.ca/economicbeneicbenefits，2016年）。彩虹鳟鱼是通过商业水产养殖生产的主要鱼类，在安大略省产生了1800万加元，莫德斯的地位是非本地的。但是，安大略省拥有许多用于新的水产养殖开发的资产，例如邻近世界上最大的淡水区（大湖），进入国家和国际市场的机会以及研究专业知识，设备和基础设施的可用性（Moccia，Naylor，＆Reid，1997）。可以大量和广泛饲养的一种本地鱼类是白鱼湖（Lazenby，Kerr和Hooper，2001）。赫伯特·渔业（Herbert Fisheries）是一家商业渔业公司，近年来注意到着陆点的减少，尤其是白鱼湖，这是大湖渔业委员会（2005）首先指出的。整个大湖区的渔业经营者证实了对白鱼湖的需求（参见Kunninen，2003年）。 为了满足这一需求，拟议的解决方案是白鱼湖的笼子培养物。但是，需要研究伙伴，可以在笼子培养地点将鱼类​​从鸡蛋中种植到陆基孵化场和市场规模（即500克）中的鱼种。 CollègeBoréal是一家高等教育机构，拥有孵化鸡蛋并抬高白鱼湖所需的专业知识和设备，直到它们达到鱼种状态。然后，开发新的潜水笼原型的开放水系统有限公司愿意提供笼子来抬高白鱼湖，直到市场大小为止，而学院的研究团队则根据自然资源和森林部的笼子文化指南，而学院的研究团队继续收集和分析与笼子文化中与笼子中的白鱼日益增长有关的数据。同时，学院的合作，两家私人公司和MNRF寻求研究将白鱼湖从鸡蛋抬高到成年人出于商业目的的可行性。
