本文概述了Ifremer最近在渔业声学和小型中上层鱼类研究方面取得的进展：i）使用一系列平台（包括自主水下航行器AUV）推动观察前沿，ii）开发测量仪器和方法以及iii）研究鱼类分布。目前，从几个频率的单波束回声测深仪收集的信息通常与从ME70多波束回声测深仪收集的数据一起收集。为实现机载数据采集控制，开发了爱马仕软件。新的MOVIES 3D软件包括用于同时进行逼真的3D可视化和后处理的模块，例如底部检测，学校提取和描述符计算以及所有声学数据的集成。几种数据分析方法正在开发中，并提出了一些初步的结果。最后，比斯开湾小型中上层鱼群的空间分布结果说明了声学在实施渔业生态系统方法方面可以发挥的作用，并且已经在发挥作用。
This paper provides an overview of the progress Ifremer has made recently in fisheries acoustics and the study of small pelagic fish by: i) pushing observation frontiers using a range of platforms including an autonomous un- derwater vehicle, AUV, ii) developing measuring instruments and methods and iii) studying fish distributions. Presently, information from several frequencies of single-beam echosounders is routinely collected together with data from the ME70 multibeam echosounder. For onboard data acquisition control the HERMES software was developed. The new MOVIES 3D software includes modules for simultaneous realistic 3D visualisation and post-processing such as bottom detection, school extraction and calculation of descriptors and integration of all acoustic data. Several data analysis methods are being developed and some initial results are presented. Finally, results on the spatial distribution of small pelagic fish schools in the Bay of Biscay illustrate the role that acoustics can play, and are already playing, in the implementation of an ecosystem approach to fisheries.
