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）有广泛的业务，而安大略省的规模不到2000万美元（见fisheries .ca/ economics benefits, 2016）。虹鳟鱼是通过商业水产养殖生产的主要鱼类，尽管它是非本地的，但在安大略省却能产生1800万美元的收入。然而，安大略省拥有许多新的水产养殖发展的优势，如靠近世界上最大的淡水区（五大湖），进入国内和国际市场，以及可获得的研究专业知识、设备和基础设施（Moccia, Naylor, & Reid, 1997）。湖白鱼是一种可以集中和广泛饲养的本地鱼类（Lazenby, Kerr, & Hooper, 2001）。赫伯特渔业公司是一家商业渔业公司，该公司注意到近年来捕捞量减少，特别是湖白鱼，这是五大湖渔业委员会（2005年）首次指出的。大湖地区的渔业经营者证实了对湖白鱼的需求（见Kunninen， 2003年）。为了满足这一需求，提出了网箱养殖湖白鱼的解决方案。然而，需要研究合作伙伴能够在陆地孵化场将鱼从卵培育成鱼苗，并在网箱养殖场所将鱼培育成市场尺寸（即500克）。博尔萨塔尔学院是一所高等教育机构，拥有孵卵和饲养湖白鱼苗直到它们达到鱼苗状态所需的专业知识和设备。然后，Open Water Systems Limited，一家开发了新型潜水网箱原型的公司，愿意提供他们的网箱来饲养湖白鱼，直到市场规模，而学院的研究团队继续根据自然资源和林业部的网箱养殖指南收集和分析与湖白鱼在网箱养殖中生长有关的数据。该学院、两家私人公司和MNRF共同合作，寻求研究将湖白鱼从卵饲养到成年的可行性，以用于商业目的。
