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 亿美元的产业，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）有着广泛的业务，而安大略省则不到 2000 万美元（见 Aquaculture.ca/economicbenefits，2016 年）。虹鳟鱼是通过商业水产养殖生产的主要鱼类，尽管它不是本地品种，但它在安大略省的收入为 1800 万美元。新水产养殖发展的许多资产，例如靠近世界最大的淡水区（五大湖）、进入国内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 和 Reid，1997）。可以集中和广泛养殖的一种本地鱼类是白鱼湖（Lazenby、Kerr 和 Hooper，2001 年），这是一家商业渔业公司，近年来其数量有所减少。上岸量，特别是白鱼湖，这是五大湖渔业委员会首次指出的（2005 年）。整个五大湖的渔业经营者都证实了对白鱼湖的需求（参见 Kunninen，2003 年）。为了满足这一需求。 ，白鱼湖的网箱养殖是拟议的解决方案，但是，需要研究合作伙伴能够在陆上孵化场将鱼从鱼卵培育到鱼种并达到市场规模（即， 500 克）在网箱养殖场，Collège Boréal 是一所高等教育机构，拥有孵化鱼卵和饲养白鱼鱼苗直至达到鱼种状态所需的专业知识和设备。潜水网箱原型，愿意提供他们的网箱来饲养白鱼湖直至上市规模，而学院的研究团队将继续收集和分析与网箱养殖中白鱼湖生长相关的数据。自然资源和林业部的网箱养殖指南 该学院、两家私营公司和 MNRF 共同致力于研究将白鲑鱼从鱼卵饲养到成鱼用于商业目的的可行性。
