The indicator species in each community type were determined using indicator species analysis (isa) (dufreвґne and legendre, 1997). a species is considered as an indicator of a group when its indicator value is significantly higher at p < 0.05 (tadesse woldemariam, 2003). the clusters were designated as plant community types and given names after two or three dominant or characteristic species representative types of crustacea which are parasitic on fish species encountered in fish farms, and to explore the effects of this parasitism on the hosts. this is effectively a study of coevolution, with the ectoparasite and host serving as models. the most recent breakthrough in the study of parasitic crustacea concerns knowledge of the role of the crustacean ectoparasite as a vector and/or
