Han Pacific Shellfish Ltd. is a small, family-owned shellfish farm near Denman Island, British Columbia. Inrecent years their oysters have not made it to the market due to unusual ocean conditions and devastatingpredation of their small oyster seed, mostly by crabs. Though ocean conditions are uncontrollable andincreasingly unpredictable, installing anti-predator nets and/or bags around the vulnerable oysters has beensuccessful in some areas to decrease losses due to predation. We propose installing different types ofanti-predator netting at Han Pacific Shellfish Ltd. specifically designed for long-term life in the ocean, todetermine which product(s) might be most effective and to adapt the existing products to suit the localconditions, as necessary. Net condition and oyster survival will be monitored by the farm staff and by the NorthIsland College research team, with net repairs/adjustments made as necessary. This project would provideimmediate and long-term benefits for Han Pacific Shellfish Ltd. by allowing more of their products to make itto consumers. In addition, valuable experience will be gained by student assistants who desire hands-ontraining in the shellfish aquaculture industry. We hope that this project will encourage further partnershipsbetween North Island College and small-scale aquaculture companies, who often have no or very limitedfinancial means for internal research and development.

汉太平洋贝类有限公司是不列颠哥伦比亚省登曼岛附近的一个小型家族贝类养殖场。近年来，由于异常的海洋条件和对其小牡蛎种子的毁灭性捕食，它们的牡蛎没有进入市场，主要是被螃蟹捕食。尽管海洋状况是无法控制的，而且越来越不可预测，但在一些地区，在脆弱的牡蛎周围安装反捕食者网和/或袋子是成功的，以减少因捕食造成的损失。我们建议在汉太平洋贝壳有限公司安装不同类型的防捕食网，专门为在海洋中长期生活而设计，以确定哪种产品(S)最有效，并按需要调整现有产品以适应当地情况。渔场工作人员和北岛学院研究小组将监测渔网状况和牡蛎存活情况，并在必要时进行渔网维修/调整。这个项目将通过让更多的产品进入消费者手中，为汉太贝类有限公司带来直接和长期的好处。此外，希望在贝类水产养殖业进行实践培训的学生助理将获得宝贵的经验。我们希望该项目将促进北岛学院与小型水产养殖公司之间的进一步合作，这些公司往往没有或非常有限的资金用于内部研究和开发。
