This book was released on 1972 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fishery for skipjack tuna (Euthynnus pelamis) in the eastern Pacific Ocean might be extended if offshore areas of high skipjack abundance were known. One would expect the numbers of skipjack in these offshore areas to be related to the distribution of known skipjack forage organisms in the micronekton. The EASTROPAC oceanographic cruises yielded net-caught micronekton samples over large parts of the eastern tropical Pacific during seven successive 2-month periods. From these samples, the occurrence of organisms known to be prey of skipjack was expressed at ml/1000 m3. Charts of night and day concentrations in the upper 200 m were produced for each of the seven periods. In the region from long 92° to 119° W the major areas of maximum concentration of potential skipjack forage remained essentially constant during most periods. Two of these areas lie parallel to the equatorial upwelling zone--one just to the north, the other just to the south. Another zonal area of abundant forage generally occurs between lat 6° and 14° N. Forage is also frequently abundant between lat 14° and 20° N and long 107° and 119° W. The concentrations of skipjack forage in these areas are comparable with those in nearshore parts of the eastern tropical Pacific, where the present skipjack fishery occurs. The abundance of skipjack in the forage-rich offshore areas might therefore be sufficient to support commercial fishing operations. Sea-surface temperatures are generally suitable for skipjack in those areas. On three recent crossings of the equatorial region at about long 119° W, skipjack appeared to be abundant in the first three areas of high forage concentration mentioned above.
