MRI: Acqusition of Electrofishing and Multi-parameter Water Sampling Instrumentation

威斯康星州德佩雷圣诺伯特学院的James R.Hodgson博士获得了一项资助，用于资助：1)一艘17英尺长的电动渔船，配备可在硬水和软水系统中进行电鱼的震击箱；2)背包电击器；3)三套多参数监测系统YSI 6600 Sondes；4)一台笔记本电脑)。这种设备被认为是共同的研究重点。此外，电子渔具和持续监测湖泊仪器将极大地增加我们作为本科教学机构的多样性。船和背包震颤器将允许我们从我们的实验湖泊中收集不同种类和大小的鱼。监测鱼类的补充、生长速度和饮食(包括通过食物网追踪13C同位素)对于当前研究设计的总体目标至关重要。获取鱼类饮食数据是我们生态系统方法的核心，以解决与系统内初级生产力与陆地有机质在为湖泊生态系统食物网提供燃料方面的重要性相关的问题。为了回答这个问题，顶级食肉动物(如大口黑鱼)在多大程度上依赖于湖泊初级生产者，或者依赖于陆地和湿地植物作为碳源，依赖于可靠的鱼类采集手段。多参数水质监测系统将使我们能够在我们所有研究的湖泊中测量一套精细尺度的湖相学特性。YSI多参数监测仪将允许在项目期间在所有实验湖泊中同时使用连续的Diel(每日)O2测量来测量整个系统的总初级生产力和呼吸。此外，该仪器将为SNC提供继续发展其能力的机会，以进一步发展其将福克斯河和绿湾作为便利的本科生水产实验(例如，生态学、湖沼学和环境化学)以及独立的学生研究和高级论文的能力。水生研究是生物和环境科学学院的重点之一，随着福克斯河水质的改善，适合大型河流栖息地的采样设备变得越来越优先。

A grant has been awarded to Dr. James R. Hodgson, St. Norbert College (SNC), De Pere Wisconsin that funds: 1) a 17-foot electrofishing boat equipped with shocker box capacities to electrofish in both hardwater and softwater systems, 2) a backpack shocker, 3) three Multi-Parameter Monitoring systems YSI 6600 Sondes, and 4) a lap top computer). This equipment is considered to share a common research focus. Additionally, the electrofishing gear and continuous monitoring limnological instrumentation will greatly increase our versatility as an undergraduate teaching institution.The boat and backpack shocker will allow us to collect fish of different species and sizes from our experimental lakes. Monitoring fish recruitment, growth rate and diet (including tracing 13C isotope though the food web) is essential to the overall goals of the current research design. Obtaining fish diet data is central to our ecosystem approach to resolving questions relative to the importance of within-system primary production versus terrestrial organic matter in fueling lake ecosystem food webs. To answer the question to what degree do top carnivores (e.g. largemouth bass) depend on lake primary producers or on terrestrial and wetland plants as a carbon source depends on reliable means of fish collection. The multi-parameter water monitoring systems will allow us to meter a suite of limnological properties at a fine scale of all our study lakes. The YSI multi-parameter monitors will allow for measurement of whole-system gross primary production and respiration using continuous diel (daily) O2 measurements over the duration of the project in all experimental lakes simultaneously.Additionally, this instrumentation will provide continued opportunities for SNC to further develop its capacity to use the Fox River and the bay of Green Bay as a convenient undergraduate aquatics laboratory (e.g. ecology, limnology and environmental chemistry) and independent student research and senior theses. Aquatic research is one of the emphases of the faculty in biology and environmental science and with the improvement of water quality of the Fox River, sampling gear appropriate for large riverine habitats becomes an ever increasingly high priority.
