Remote Sensing of Pelagic Fish Stock

这一小企业创新研究第一阶段项目的目的是开发一种被动多光谱成像系统，用于远程评估中上层鱼类和海洋哺乳动物种群。渔业的养护、管理和合理利用正成为一个紧迫而日益具有挑战性的问题。目前，对中上层鱼类种群的评估是通过人类从飞机上进行目视观察来确定鱼群的位置、确定其物种和估计其生物量。由于观察者的偏见、看法和解释各不相同，这些方法过于不精确和不充分，而且缺乏可以进行定量分析的客观永久记录。该提案涉及需要新的仪器和方法，以获取关于中上层鱼类种群和生境资源的准确定量数据。第一阶段项目的目标是建立远程成像光谱仪的试验板原型，并评价其在实验室（海洋水族馆）远程探测和识别选定物种的能力。

This Small Business Innovation Research Phase I project is for development of a passive multispectral imaging system for remote assessment of pelagic fish and marine mammal stocks. The conservation, management, and rational utilization of fisheries is becoming an urgent and increasingly challenging problem. Currently, assessment of pelagic fish stocks are conducted through human visual observations from aircraft to locate schools of fish, determine their species and estimate their biomass. These methods are too imprecise and inadequate due to variability in observer's bias, perceptions and interpretations, and lack an objective permanent record that can be subjected to quantitative analysis. This proposal addresses the need for novel instrumentation and methods to acquire accurate quantitative data on pelagic fish stocks and habitat resources. The objective of the Phase I project is to build a breadboard prototype of the remote imaging spectrometer and to evaluate it for its ability to remotely detect and identify selected species in the laboratory (marine seaquarium).
