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.

小规模渔业是海洋时代沿海遗产的一部分，但关于各种渔业对危险鱼类或其他鱼类的相互关联和累积影响的研究很少。要有效地进行保护，需要更多的资料，如果完成更复杂的研究，就可以获得更多的资料。社会参与是建立和维持可持续和健康的鱼类种群的一个关键因素。许多市民喜欢休闲垂钓，他们的活动可以对鱼类种群产生深远的影响，因为鱼类捕捞可以极大地影响保护工作。预测对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。渔业科学再也不能孤立地进行，因为人类活动对鱼类种群减少的影响越来越大，需要更多的数据来说明影响。我的长期研究目标是更好地了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，并在建模这样的系统中考虑随机过程。我的短期研究目标将侧重于评估与渔业长期监测战略和分析方法相关的不确定性。公民科学志愿者被忽视了作为一个重要的来源，历史和新的信息，可以帮助保护工作。我创建了一个由商业渔民和休闲钓鱼者组成的管理渔业网络，以增加和加强对高危海洋鱼类的数据收集。*** 我的目标是：1）通过实地采样收集合适的数据，以填补处于危险中的海洋鱼类物种生态研究的种群指标空白; 2）发展和支持我的管理渔民网络，以收集新的和汇编历史数据。这些数据将用于综合种群模型和模拟研究，以3）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有关危险鱼类的空间和时间信息。志愿者将提供渔获记录，包括从一个鱼类标签计划返回的标签。我的研究计划的优势在于利用志愿者在一个大的空间区域贡献更多的信息，而不是通过研究人员只采样来实现。我提出的建模和仿真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目前在理解加拿大鱼类种群下降的核心的种群指标方面的关键知识差距。
