A number of parasites was found on the gills and corpus.
Dactylogyrid species were found to co-occur on the gills of roach with up to six species found on the same host individual.
The gills were removed and rinsed, and the arches were examined individually.
Oysters were later dissected on ice, determining the wet weight of gills, digestive gland and all remaining tissues.
The sunfish were revived by irrigating the gills with fresh aquarium water.
On the gills of all the catfish examined there occurred a leech which was sometimes present in enormous numbers.
The niches of both congeners were greatly segregated and a low overlap was found within all gill arches.
Several explanations have been proposed to explain the transverse partitioning distribution of gill ectoparasites.
