AN ANALYSIS OF A NEW APPROACH TO FULLER UTILIZATION OF JAPANESE ANCHOVY RESOURCES BY ARTIFICIAL STOCK ENHANCEMENT OF JAPANESE SPANISH MACKEREL
Abstract:
According to recent surveys, the very abundant Japanese anchovy (Engraulis japonicus Teminck & Schlegel) resources in the Bohai, Huanghai and East China Sea reach to two million tons. Certainly, fishing should be an important method for exploitation of this resources. On the other hand, the Japanese anchovy can be "Transformed" into Japanese Spanish mackerel, Scomberomorus niphonius (Cuvier et Valenciennes) (which is of higher quality and economic value), through the marine food chain as the latter feeds mainly on the former. Stocking juveniles of Japanese Spanish mackerel into the seas will result in an increase in its stock size, and they can easily be caught by traditional drift nets after growing pu. Some primary suggestion are offered and comparison of the favorable and unfavorable conditions are discussed.
