For the effective echo survey for fish resource estimation, the basic study has been conducted for two years and the following results were obtained.1.Data analysing system for echo survey using computer network was developed. It realized the parallel processing of data acquisition, analysis, and storage.2.High accuracy processing of the near bottom echo which is important for a demersal fish survey was investigated.3.Target strengths of juvenile swimbladder fish were measured. Juvenile fish often scatter acoustic waves well due to their resonance structure.4.The three-dimensional analysing method of scanning sonar which is effective tool for echo survey has developed.5.The new calibration procedure using standard sphere was proposed. It certifies to obtain the confident echoes from the standard target for calibration.6.Effective acoustic survey designs were discussed. The adaptive circumstance data, e.g., CTD data, Satellite image, ADCP data were gathered and generalized for echo data analysis.

为了有效地进行鱼类资源回声调查，进行了两年的基础研究，取得了以下成果：1.研制了回声调查数据计算机网络分析系统。实现了数据采集、分析和存储的并行处理; 2.研究了底栖鱼类调查中重要的近底回波的高精度处理; 3.测量了幼鱼的目标强度。幼鱼的共振结构使声波具有良好的散射特性。4.研究了有效的回波测量工具--扫描声纳的三维分析方法。5.提出了标准球标定新方法。实验结果表明，该方法可以从标准目标上获得可靠的目标回波。6.讨论了有效的声学测量方案。自适应环境数据，例如，收集CTD数据、卫星图像、ADCP数据，并将其用于回波数据分析。
