Abstract

The indicator value methods are important to conservation biology because it is conceptually straight forward and allows researchers to identify bioindicators for any combination for habitat types or areas of interest. (Mc Geoch & Chown, 1998). The spatial distribution of parasitic copepods from teleost fishes (Chelon labrosus, Mugil cephalus, Liza aurata and Dicentrarchus labrax) was studied in two sites (Annaba gulf and El Mellah lagoon) in the eastern Algeria coastline using indicator species analysis (Indval) to identify parasite species as bioindicators of a given ecosystem during 2005-2008, also identified parasites as bioindicators relative to host. The randomization test identified four parasite species (Caligus mugilis, Ergasilus liza, Lernanthropus mugilis, Caligus minimus) having a significant indicator value for the site and six indicators for the host (Caligus mugilis, Ergasilus bora, Lernanthropus kroyeri, Lernanthropus mugilis, Caligus minimus, Ergasilus liza). Data on species composition and infection levels would help improve the monitoring and management of parasitism in Mugilidae and Moronidae populations. However none pointed out the role of parasitic copepods as bioindicators in Algerian costs.
