STUDIES ON THE INTERSPECIFIC RELATIONS BETWEEN COMMON MACKEREL AND HORSE MACKEREL 1. Analysis of Fluctuations in Their Abundance over a Long Period
고등어와 전갱이의 종간상호관계 1. 장기변동의 해석
Abstract
The present study deals with dynamical relationships between variations of common mackerel and horse mackerel catches in the waters adjacent to Korea for the years 1926 to 1969. The materials used here were obtained from Fishery Statistics published by the Bureau of Fisheries and the Fisheries Research and Development Agency of Korea, Secular variations of common mackerel and horse mackerel catches were classified intc five stages from A to E as shown in Fig. 2. As to variations of catch, the two species have alternating cycle trends occurring every ten years. With regard to the long period trend of catch, there is no correlation between annual variations of the species caught. Dynamical relationships between the two species showed a somewhat different pattern of catch as they transferred from one stage to another of the secular variations.
