Similarity in parasite community structure may be used to trace latitudinal migrations of Odontesthes smitti along Argentinean coasts
The aims of this study were to determine the existence of migratory movements and to identify ecological stocks of the silverside Odontesthes smitti along its distribution in the Southern Atlantic Ocean, using metazoan parasites as biological tags. Samples were obtained from San José Gulf (SJ) (42°...
