Resumen:
In Argentina no studies of component community of macroparasites of freshwater fish have been
performed.
The aim of this study was to describe and compare the macroparasite component communities
between 3 oligotrophic lakes with differences in areas, presence of shoreline vegetation and/or
fish assemblages, hypothesizing that the macroparasite richness is different in relation to the
combination of these characteristics.
The smallest lake has an area of 0.01 km 2 and the medium 16.4 km2 , both with vegetated
shoreline. The biggest one has an area of 557 km 2 without vegetation in the shoreline. Samples
of fishes were collected seasonally with nets in different sites in each lake. In total, the following
native species were captured: 1,150 Galaxias maculatus, 97 Galaxias platei, 28 Diplomystes
viedmensis, 27 Odontesthes hatcheri and 306 Percichthys trucha. The exotic species comprised:
213 Oncorhynchus mykiss, 72 Salvelinus fontinalis and 18 Salmo trutta. All fish organs were
examined, and macroparasites were identified to calculate richness.
The most common taxa were digeneans, and nematodes. Richness was 18 in the smallest lake
with 2 native and 1 exotic fish species, 31 in the medium lake and 27 in the largest both with the
same assemblage of fish species, 5 native and 3 exotic.
The lowest macroparasites species richness was found in the smallest lake with the lower fish
assemblage. When the medium and large lakes are analyzed, macroparasite richness increased at
least 70%. Considering the same fish assemblage is present in both lakes, differences in richness
can be attributed to the presence of refugees associated with shoreline vegetation.

with 2 native and 1 exotic fish species, 31 in the medium lake and 27 in the largest both with the
same assemblage of fish species, 5 native and 3 exotic.
The lowest macroparasites species richness was found in the smallest lake with the lower fish
assemblage. When the medium and large lakes are analyzed, macroparasite richness increased at
least 70%. Considering the same fish assemblage is present in both lakes, differences in richness
can be attributed to the presence of refugees associated with shoreline vegetation.
