Small-scale fisheries are a part of the coastal heritage of the Maritimes, yet a paucity of research exists on the linked and cumulative impacts of various fisheries on at-risk or other fishes. For effective conservation, more information is required and is accessible if more sophisticated studies are completed. Societal involvement is a key element to establishing and maintaining sustainable and healthy fish stocks. Many citizens enjoy recreational angling, and their activities can have a profound effect on fish populations because fish harvesting can greatly affect conservation efforts. Predicting risks to future fish stocks is fundamental to developing conservation plans, and understanding the interactions of anthropogenic effects and fish population dynamics is currently a barrier to this goal in small-scale fisheries. Fisheries science can no longer be conducted in isolation because of the growing influence of human actions on declining fish stocks and the need for more data to characterize effects.My long-term research goals are to better understand aquatic ecosystem regime shifts as they are affected by changing environments and human influences, and to account for stochastic processes in modeling such systems. My short-term research goals will focus on assessing the uncertainty associated with long-term monitoring strategies and analysis methods in fisheries. Citizen Science volunteers are overlooked as an important source for historic and new information that can help conservation efforts. I have created a stewardship fisheries network consisting of commercial fishers and recreational anglers to increase and enhance data collection on at-risk marine fishes. My objectives are 1) To collect suitable data to fill gaps in population metrics for ecological studies in at-risk marine fish species through field sampling and 2) growing and supporting my stewardship fishers network to collect new, and compile historical data. This data will then be used in integrated population models and simulation studies to 3) explore long-term population changes by testing conservation actions within the model framework. My students and I will collect spatial and temporal information on at-risk fishes through my fisheries network. Volunteers will provide fish catch records including tag returns from a fish tagging program. The strength of my research program is in leveraging volunteers to contribute substantially more information in a large spatial area than would otherwise be realized through researcher only sampling.My proposed modeling and simulation research integrates ecological processes and sampling regimes into conservation planning. This approach will help identify critical knowledge gaps in population metrics that are currently at the heart of understanding declining Canadian fish stocks.

小规模渔业是海洋地区沿海遗产的一部分，但关于各种渔业对濒危鱼类或其他鱼类的相互关联和累积影响的研究却很少。为了有效的保护，需要更多的信息，如果完成了更复杂的研究，就可以获得更多的信息。社会参与是建立和维持可持续和健康鱼类资源的关键因素。许多市民喜欢休闲垂钓，他们的活动会对鱼类数量产生深远的影响，因为鱼类捕捞会极大地影响保护工作。预测未来鱼类种群的风险是制定养护计划的基础，而了解人为影响和鱼类种群动态之间的相互作用目前是小规模渔业实现这一目标的障碍。渔业科学不能再孤立地进行，因为人类活动对不断减少的鱼类种群的影响越来越大，而且需要更多的数据来描述这些影响。我的长期研究目标是更好地理解水生生态系统制度的变化，因为它们受到不断变化的环境和人类影响的影响，并在模拟这样的系统中考虑随机过程。我的短期研究目标将集中在评估与渔业长期监测策略和分析方法相关的不确定性。公民科学志愿者作为历史和新信息的重要来源被忽视了，这些信息可以帮助保护工作。我建立了一个由商业渔民和休闲垂钓者组成的渔业管理网络，以增加和加强对濒危海洋鱼类的数据收集。我的目标是：1)通过实地取样收集合适的数据，填补濒危海洋鱼类生态研究中种群指标的空白；2)发展和支持我的管理渔民网络，收集新的和汇编历史数据。然后，这些数据将用于综合种群模型和模拟研究，通过在模型框架内测试保护行动来探索长期种群变化。我和我的学生将通过我的渔业网络收集濒危鱼类的时空信息。志愿者将提供鱼类捕获记录，包括从鱼类标签项目中返回的标签。我的研究项目的优势在于利用志愿者在一个大的空间区域提供更多的信息，而不是通过研究人员的抽样来实现。我提出的建模和模拟研究将生态过程和采样制度纳入保护规划。这种方法将有助于确定种群指标方面的关键知识差距，这是目前了解加拿大鱼类种群下降的核心。
