Variación local y geográfica de las infracomunidades de parásitos de la anchoveta Engraulis ringens en Chile
We compared the local and geographical variation of parasite infracommunities of the anchovy Engraulis ringens from 3 fishing areas off Chile (Caldera, Talcahuano and Valdivia), in 7 samples taken from different vessels. Body lengths of fish in the samples, richness, diversity and composition of par...
