A fundamental understanding of the biology of a species is both intrinsically important and vital to maintaining healthy populations under fishing pressure. This project investigates the biologically enigmatic spot prawn in British Columbia (BC) using theoretical models and field work. Spot prawns live in deep water on the sea bed off the coast of BC and begin life as males before transitioning to females for the final year or two of their life. Despite how important they are to humans as a commercial fishery, we know relatively little about their fundamental biology. This biological information is intrinsically interesting and is also imperative for fisheries management that will maintain consistent abundance of spot prawns going forwards. We will use long-term data sets, quantitative modelling techniques, and fieldwork to (1) build new tools to investigate uncertainties in spot prawn population biology, (2) learn from the current management approach in BC, and (3) identify opportunities to build resilience in the fishery in the face of a changing climate. Effective long-term fisheries management hinges on a match between management practices and biology. This research program will aim to pro-actively further our biological understanding of spot prawns and support decisions for a well-managed fishery in the future.

对物种生物学的基本了解对于在捕捞压力下维持健康种群既具有内在的重要性，也是至关重要的。本项目使用理论模型和野外工作对不列颠哥伦比亚省(BC)的生物谜团斑虾进行了调查。斑对虾生活在公元前海岸外海床的深水中，开始以雄性的身份生活，然后在生命的最后一到两年过渡到雌性。尽管作为商业渔业，它们对人类有多么重要，但我们对它们的基本生物学知之甚少。这些生物信息本质上很有趣，对于渔业管理也是必不可少的，这样才能保持未来斑虾的一致丰度。我们将使用长期数据集、定量建模技术和实地工作来(1)建立新的工具来调查对虾种群生物学中的不确定性，(2)学习不列颠哥伦比亚省目前的管理方法，以及(3)确定在面对气候变化时建立渔业弹性的机会。有效的长期渔业管理取决于管理做法与生物学之间的匹配。这项研究计划将旨在积极地促进我们对斑虾的生物学理解，并为未来良好管理的渔业提供决策支持。
