ON THE OCCURRENCE OF THE POSTLARVAE AND JUVENILES OF DOLPHINS, Coryphaena hippurus L. AND C. equiselis L. IN THE EAST CHINA SEA
Abstract:
This report deals with the pelagic postlarvae and juveniles of the common dolphins, Coryphaena hippurus, and the juveniles of the pampano dolphins C. equiselis, collected in the East China Sea. They were captured at the surface on the deep sea stations by the surface towing at dusk, or at dawn occasionally. Most of them were distributed along the high isohaline off the Kuroshio current and its adjacent areas, so they are the dominant species off the Oceanic area of the Kuroshio current. According to the development of the smallest postlarvae and its sizes, the spawning season of the common dolphin seems to extend from May to late August and the pampano dolphin breeds throughout summer to fall respectively.
