Vertical distribution of eggs and larvae ofEngraulis encrasicolus in stratified waters of the western Mediterranean

  • I. Palomera

Abstract

The vertical distribution of the eggs and larvae of the European anchovy (Engraulis encrasicolus) in the western Mediterranean Sea in June 1984 and Agust 1985 was analyzed based on multiple plankton tows carried out at varying depths and using nets equipped with opening and closing mechanisms. Hydrographic parameters such as temperature, salinity, and chlorophylla were recorded simultaneously. Maximum abundance of anchovy eggs and larvae always occurred above the thermocline, even when maximum chlorophylla concentrations were located below the thermocline. Larval distribution appeared to be associated with the availability of suitable food organisms. As in other clupeoid species, the anchovy larvae carried out vertical migrations related to the photoperiod.
