We also assume that the oncomiracidia may possibly migrate to the gills from the body surface.
The fishery has been sampled continuously since 1970, using gill nets, seine nets, traps and electric fishing as appropriate to season and conditions.
This final segregation was more apparent in the second and third gill arches.
As dactylogyrids die quickly after the death of fish, only the left side of the gill apparatus was investigated for parasite species identification.
The left side of the gill apparatus was investigated for parasite distribution.
The mucus and gill filaments were used for the experiment.
Each gill arch was examined and the number of metacercarial cysts counted.
Several explanations have been proposed to explain the transverse partitioning distribution of gill ectoparasites.
