鱼群侦察是一种捕捞性侦察，是保证联合渔法获得良好结果的重要因素之一。所以鱼群侦察的优劣会直接影响到捕捞的成败。目前，各地水库的侦察技术都以耳闻目睹的经验判断为主。在少数技术力量较强的生产单位，也试用海洋用的鱼群探测器来侦察水库鱼群情况，但由于仪器性能上的 Fish reef detection is a kind of fishing reconnaissance and is one of the important factors to ensure the good result of joint fishing. Therefore, the pros and cons of fish detection will directly affect the success or failure of fishing. At present, the reconnaissance technologies of reservoirs are judged by the experience they have heard and heard. In a small number of strong production units, but also the use of marine fish detectors to detect the situation of the reservoir fish, but due to the performance of the instrument
