水库渔业生产的实践证明:准确地掌握水库鱼群活动的规律,是“赶拦刺张联合渔法”和“围网渔法”取得良好捕捞效果的重要前提。否则,在数万亩甚至数十万亩的大型水库开展捕捞生产将很难保证大鱼群的捕获,从而影响水库渔业的稳产高产。国内水库目前常用的鱼群侦察方法有使用半导体探鱼仪和用生态学的方法掌握鱼群活动规律侦察鱼群等二种,而以后者为主。遵照毛主席“要认真总结经验”的指示,本文根据生产实践中对水库鱼类活动规律的一些认识,探讨水库鱼群的侦察,供讨论。
The practice of reservoir fishery production proves that accurately grasping the regularity of the activities of reservoir fish groups is an important prerequisite for achieving good fishing effect by “Combining Barges and Tailings Fishing Law” and “Purse Seining Law”. Otherwise, fishing in large reservoirs of tens of thousands of mu or even hundreds of thousands of mu will make it hard to ensure the capture of large fish stocks, thus affecting stable and high-yielding of reservoir fisheries. At present, the domestic reservoirs commonly used methods of fish detection include the use of semiconductor fish finder and the ecological method to master the fish movement rules of the two kinds of reconnaissance fish, while the latter. In accordance with Chairman Mao’s “serious experience”, this paper explores the reconnaissance of reservoir fish stocks for discussion based on some understanding of the law of reservoir fish activities in production practice.
