项目摘要

Records of abundant fish production indicate Native Hawaiians' wealth of knowledge about sustainable and effective fishpond management practice. The Mokauea fishpond is located on Mokauea island of the Kalihi ahupua'a just off the southern coastline of O'ahu. In the early 1900's, this region was the site of over forty fishponds, producing nearly one ton of fish per year. Currently, the Mokauea fishpond is not functional, even though the basic water quality parameters are within acceptable ranges for fish production. This investigation aims to understand the workings of the Mokauea fishpond and other Hawaiian fishponds. The research will utilize tools from statistics and applied mathematics, and, just as importantly, will integrate the ancient knowledge from Native Hawaiian cultural and fishpond practitioners. The results of the study will provide insights into traditional Native Hawaiian sustainable aquaculture practices, viewed from the lenses of Western scientific and mathematical language. Further, findings will contribute information valuable to addressing the increasingly important issue of sustainable food production. To achieve the goals of this investigation, data relating to the physical attributes of the Mokauea pond will be collected over a year-long monitoring study. These data will be analyzed using mathematical modeling software to develop models of the dynamic relationships between water temperature and circulation patterns at play in the fishpond. The model for the temperature profile will be drawn based on the energy balance principle, while the water circulation model will be based on the shallow water circulation model (Saint Venant equations). Data from the sustained observation along with conversations with Native Hawaiian aquaculture practitioners will inform the mathematical modeling process. Finally, the investigation aims to develop, organize, and maintain an online hub for the data collected in the study as well as other available data and studies on the Mokauea fishpond and surrounding areas.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

丰富的鱼类生产记录表明夏威夷土著人对可持续和有效的鱼塘管理实践的丰富知识。Mokauea鱼池位于O'Arena南部海岸线附近的Kalihi ahupua'a的Mokauea岛上。在20世纪初，这个地区是四十多个鱼塘的所在地，每年生产近一吨鱼。目前，Mokauea鱼塘无法正常运作，尽管基本水质参数在鱼类生产可接受的范围内。这项调查旨在了解Mokauea鱼塘和其他夏威夷鱼塘的运作情况。这项研究将利用统计学和应用数学的工具，同样重要的是，将整合夏威夷土著文化和鱼塘从业者的古老知识。该研究的结果将从西方科学和数学语言的角度出发，深入了解夏威夷原住民传统的可持续水产养殖实践。此外，调查结果将为解决日益重要的可持续粮食生产问题提供宝贵的信息。为了实现这一调查的目标，有关的Mokauea池塘的物理属性的数据将收集超过一年的监测研究。这些数据将使用数学建模软件进行分析，以建立鱼塘中水温和循环模式之间动态关系的模型。温度分布模型将基于能量平衡原理绘制，而水循环模型将基于浅水循环模型（圣维南方程）。来自持续观察的数据沿着与夏威夷土著水产养殖从业者的对话将为数学建模过程提供信息。最后，该调查旨在开发、组织和维护一个在线中心，用于收集研究中收集的数据以及其他关于莫卡乌厄鱼塘和周边地区的可用数据和研究。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
