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.

从根本上了解一个物种的生物学，对于在捕捞压力下维持健康的种群既具有内在的重要性，也至关重要。该项目使用理论模型和实地工作调查了不列颠哥伦比亚省（BC）生物学上神秘的斑点虾。斑点虾生活在不列颠哥伦比亚省海岸附近海床的深水中，开始作为雄性生活，然后在生命的最后一两年过渡到雌性。尽管它们作为商业渔业对人类有多么重要，但我们对它们的基本生物学知之甚少。这种生物信息本身就很有趣，对于渔业管理也是必不可少的，这将保持斑点虾的持续丰富。我们将使用长期数据集，定量建模技术和实地考察，以（1）建立新的工具来调查斑点对虾种群生物学的不确定性，（2）从BC省目前的管理方法中学习，（3）确定在气候变化的情况下建立渔业恢复力的机会。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。这项研究计划的目的是积极主动地促进我们对斑虾的生物学理解，并支持未来管理良好的渔业决策。
