Abstract

Samplings of the Emerita anafoga were taken biweekly with traps "cafan" on San Jase beach (Lambayeque-Peru) from March 1996 lo November 1997. Cephalotoraxic length (mm) and total weight (0,001 g) was registered and the alimentary canal, gonads, and muscles were analyzed in order to took lor parasites. The data were processed comparing statistically March 96 -March 97 (year 96) against those of the Aprit -November 97 (El Niño 1997-98). The following parasites were present during 1996: Eutetrarhynchus (cestod), Polymorphus (acantocephala), Proleptus and Spiruroidea (nematode) and Marytrema (digeneo). During "El Niño 1997 -98" also appeared the cestod Nybelínia and another digeneo. The prevalence lor Eutetrarhynchus and the nemalodes, was major during "El Niño 1997-98" lor bolh females and males: This same tendency was presented in the analysis 01 the number 01 the parasites/ ind., but diminished Pofymorphus and Marytrema. However, "El Niño 1997-98" events have no significant effect on the comparative allometric factor. The analysis of the evolution 01 the parasites throughout time evidenced that Eutetrarhynchus and the nematodes Proleptus and Spíruroídea, increased since February 1997 (befare "El Niño 1997-98" beginning), which constitute a possibility to consider them as good biological indicators in early detection of "El Niño 1997-98" events.
