In this study, an important ornamental fish, Betta splendens (Osphronemidae), from three different Brazilian states was examined for parasitic infestations. Smears with parasites were impregnated with silver nitrate or stained using Giemsa for taxonomic evaluation. A disc-shaped trichodinid with a body diameter of 39.7 ± 3.3 µm, adhesive disc diameter of 32.9 ± 3.1 µm and denticulate ring diame...

Present theory states that in species-poor assemblages interactions among species are negligible and assemblage structure is a result of host/parasite interactions. A corollary to this theory is that parasite species assemblages should behave as accumulations of multiple-kind items drawn from a population in which only the relative probability of drawing each kind varies. This study was designe...

background: in anzali lagoon, there are some endemic and exotic fishes. the present study was conducted to compare the parasitic fauna of blicca bjeorkna , as an endemic fish and hemicul­ter leucisculus , as an introduced fish to the lagoon. methods: a parasitological investigation was done on 78 specimens of b. bjoerkna and 114 of h. leu­cisculus . the fishes were collected from august 2009 to...
