Aquaculture is recognized as a growing source of employment and offers the possibility for social and economic improvements in communities with limited industrial alternatives. Canadian aquaculture is considered to have entered its "second phase" as an industry and to remain competitive, it will have to develop new species for commercial cultivation. Arctic charr is an excellent intensive culture species that has a cold water requirement. While cultured charr commands a high price, global production is limited by these cold water restrictions. Therefore, the supply of charr is not expected to meet the growing demand and market prices should remain at a premium. Because of its geography and climate, Canada has the potential to account for the majority of the world's production of charr. A major impediment to the expansion of Arctic charr farming is the inconsistent availability to fish farms of high quality fish with well-defined production parameters. One step that would facilitate the growth and competitiveness of the Canadian Arctic charr industry is the selection of strains that exhibit economically important traits such as fast growth, reduced early maturation, and increased salinity tolerance using state of the art genomic tools. As such, an ongoing project supported by Atlantic Canada Opportunities Agency/ Atlantic Innovation Fund (AIF) aims to provide the molecular genetic information that will increase the efficiency of artificial selection and breeding programs when combined with traditional quantitative genetic methods. This NSERC CRD project proposes to use leveraged funds to add a value added component that will capitalize on existing efforts of the AIF project. The objectives of the CRD project are to (1) develop of genomic resources for Arctic charr and (2) apply those genomic resources in the selective breeding programs of our industrial partners and collaborators. Specifically, the leveraged funds will be used to update the genotyping methodology thus increasing resolution and potential for application to the Canadian Arctic charr industry. This effort will also provide enhanced training of a PhD student in state of the art methods used in fish breeding.

水产养殖被认为是一个日益增长的就业来源，为工业替代品有限的社区提供了改善社会和经济的可能性。加拿大水产养殖业被认为已进入其作为一个产业的“第二阶段”，为了保持竞争力，它将不得不开发新的商业养殖物种。北极红点鲑是一种优良的集约化养殖物种，具有冷水需求。虽然养殖的木炭价格很高，但全球生产受到这些冷水限制的限制。因此，预计木炭的供应无法满足日益增长的需求，市场价格应保持溢价。由于其地理和气候，加拿大有可能占世界木炭产量的大部分。扩大北极红点鲑养殖的一个主要障碍是，养鱼场无法获得具有明确生产参数的高质量鱼类。促进加拿大北极红点鲑产业增长和竞争力的一个步骤是使用最先进的基因组工具选择表现出经济上重要性状的菌株，如快速生长，早熟减少和耐盐性增加。因此，由大西洋加拿大机会局/大西洋创新基金（AIF）支持的一个正在进行的项目旨在提供分子遗传信息，当与传统的定量遗传方法相结合时，将提高人工选择和育种计划的效率。这个NSERC CRD项目建议使用杠杆资金来增加一个增值组件，该组件将利用AIF项目的现有努力。CRD项目的目标是（1）开发北极红点鲑的基因组资源;（2）将这些基因组资源应用于我们的工业合作伙伴和合作者的选择性育种计划中。具体而言，杠杆资金将用于更新基因分型方法，从而提高分辨率和应用于加拿大北极红点鲑产业的潜力。这项工作还将加强对一名博士生的培训，使其掌握鱼类育种的最新方法。
