    摘要:

    本文分析了秋汛带鱼对水温舌锋伸展的聚集反应,这种聚集反应常出现在舌锋延伸与流界的交汇区、带鱼的适温区域内,舌锋线附近聚集密度较大,渔业产量也与聚集强度成正比。利用这一现象,在现有的技术条件下,从海洋表层水温分布着手,分析水团和海流的分布变动情况,结合当时生产实际和鱼类生物学状况,进行中心渔场短期预报。预报实践初步表明,这种方法是可行的,它对渔业生产有重要价值,对于探讨鱼发规律和预报方法也是有益的。

    Abstract:

    This article deals with the aggregation response of autumn hairtail fish to the temperature in the stretching water tongue. The response usually occurs in the joint area of tongue front and current rip where the temperature is suitable to the fish. It is denser aggregated near the tongued central line. The fishing yeild grows with the density becoming greater, which makesr it possible to make sport'time prediction aboul the central fishing ground by analysing the changes in distribution of water-masses and ...
