The infection of Scomberomorus brasiliensis by the myxozoan Kudoa sp. is reported. The parasites formed plasmodiae inside the skeletal muscle fibres. The spores were quadrate in apical view and bell-like shaped in lateral view, containing four equally sized more or less rounded polar capsules. No detrimental effects were observed in the host, namely muscle liquefaction. The importance of these ...

The present study investigated the effects of first record of co-infection of three Clinostomum sp.; Clinostomum Complanatum (Rudolphi, 1819), C. tilapiae (Ukoli, 1966), and Euclinostomum hetereostomum (1809) in Tilapia zilii. There was differential parasitic effects resulting in selection for relatively better adaptiveness to host's microhabitats, more population size, and frequent host locati...

A morphological and genetic reassessment of the phylogeny and taxonomy of the dwarf zoarcid fish Lycodes teraoi Katayama, 1943 indicated that the species, a senior synonym of Lycodes sadoensis Toyoshima & Honma, 1980, should be placed in the genus Petroschmidtia. A redescription of P. teraoi is provided, with remarks on its taxonomy. Numerous specimens revealed a wide distribution of P. teraoi ...
