Horizontal distribution of Peruvian anchoveta related to oceanographic conditions in the period 1986-2000
Keywords:
Peruvian anchovy, distribution, oceanographyAbstract
An analysis of the anchovy distribution using Geographic Information System techniques was made. The data were obtained from hydroacoustic summer evaluation cruises for Peruvian pelagic fishes, carried out from 1986 to 2000. The anchovy horizontal distribution was analysed related to oceanographic parameters like sea surface temperature, sea surface salinity and sea surface chlorophyll a concentrations. The results indicated that the anchovy horizontal distribution is associated to surface oceanographic characteristics as ranges of temperature, salinity and chlorophyll a; but it seems that the main parameter of distribution is the salinity.
