Research using parasites infish population studies in the South Eastern Pacific (SEP) is summarized. There are 27 suchstudies (snapshots mainly) in single host species sampled at different geographic localities and at somewhat similar times.They have been devoted mainly to economically important species, though others on coastal and intertidalfish or on less- ornon-commercial species provide insights on scales of temporal and spatial variation of parasite infracommunities. Later, weassess whether the probability of harbouring parasites depends on the host species body size. Our results indicate that astronger tool forfish population studies may be developed under regular (long term) scrutiny of parasite communities,especially of smallfish host species, due to their larger variability in richness, abundance and total biomass, than in largefishspecies. Finally, it might also be necessary to consider the effects offishing on parasite communities as well as the naturaloscillations (coupled or not) of host and parasite populations. |
