摘　　要：针对鱼群在给食前后的状态和食物需求之间的关系,文章设计一种基于水听器及NI MY-DAQ采集卡的鱼声信号采集系统方案,通过水听器感知鱼在不同状态下的声信号,经采集卡和虚拟仪器(LabVIEW)编程实现模数转换、信号调理等环节,实现鱼声信号的采集、存储、显示与简单的分析任务。测试结果表明,该方案可以实现不同状态下鱼声信号的采集与处理。According to the relations between fish status and food demands, a fish acoustic signal acquisition system based on NI myDAQ card and LabVIEW development tools was designed. The acoustic signals were received by the Hydrophone and then perceived by the acquisition card for analog-digital conversion, signal conditioning and other operation to perform the task of acquisition, storage, display and simple analysis. The test results indicated the method was effective and the signals were identical with expectation.
