Between March 2000 and April 2001, 63 specimens of N. barba from Angra dos Reis, coastal zone of the State of Rio de Janeiro (23 degrees 0' S, 44 degrees 19' W), Brazil, were necropsied to study their infracommunities of metazoan parasites. Fifteen species of metazoan parasites were collected: 2 digeneans, 1 monogenean, 2 cestodes, 1 acantocephalan, 2 nematodes, 6 copepods, and 1 hirudinean. Ninety-six percent of the catfishes were parasitized by at least one metazoan parasite species. A total of 646 individual parasites was collected, with mean of 10.3 +/- 16.6 parasites/fish. The copepods were 37.5% of the total parasite specimens collected. Lepeophtheirus monacanthus was the most dominant species and the only species with abundance positively correlated with the host total length. Host sex did not influence parasite prevalence or mean abundance of any species. The mean diversity in the infracommunities of N. barba was H = 0.130 +/- 0.115 with no correlation with host's total length and without differences in relation to sex of the host. One pair of endoparasites (Dinosoma clupeola and Pseudoacanthostomum floridensis) showed positive association and covariation between their abundances and prevalences. The parasite community of N. barba from Rio de Janeiro can be defined as a complex of species with low prevalence and abundance and with scarcity of interspecific associations. However, because of both the presence of assemblages of sympatric ariid species as well as the spawning behavior characteristic of these fishes, additional comparative studies of the parasite component communities of ariids are necessaries to elucidate this pattern.

“…This species was also reported parasitizing B. chrysura from Florida, USA (Pearse 1952, Causey 1955. Subsequently, Luque and Paraguassú (2003) redescribed it from specimens found in the Argentine croaker, Umbrina canosai Berg (Sciaenidae) from Rio de Janeiro, Brazil. The present finding of L. leidyi is the first record of this species from Argentinean waters.…”

Subsequently the female was redescribed and the male was described for the first time by Luque and Paraguassú (2003) from Pagrus pagrus from the coastal zone of the State of Rio de Janeiro, Brazil. This is the first record of L. caudatus from Argentinean waters.…”

Increasing knowledge of the biodiversity of parasitic copepods in the Argentinean Sea will provide a baseline against which changes in the distribution of marine biota can be detected. We provide new information on the distribution of 13 known species of parasitic copepods gathered from 11 species of marine fishes from Argentinean Sea, including 7 new host records and 9 new locality records. These species are:

“…Some species of Lernanthropus are strictly host specific, whereas many are parasitic on several species of fish within one or several genera (8,17). Lernanthropus is known to cause such pathological changes as, necrosis in epithelial tissue and ligament, increased mucus secretion, narrowing in capillary veins meanwhile Lernanthropus attaches to the gill filaments with third leg (7).…”

Summary: Because of a 1.5% daily mortality was recorded in sea bass (Dicentrarchus labrax) reared in floating-cage farm in Aegean Sea coast of Turkey, 15 sea bass were examined parasitologically and pathologically, in March 2010. Diplectanum aequans (Wagener, 1857) and Lernanthropus kroyeri (van Beneden, 1851) were detected in all fish. Of the 15 sea bass dissected, 100% were infected by Diplectanum aequans (Wagener, 1857), and mean intensity of infection was 31.9, 100% were infected by Lernanthropus kroyeri (van Beneden, 1851) and mean intensity of infection was 11.4, respectively. In the pathological examination of the gills, anemia, whitish mucuoid exudate and greenish egg sac belong to female Lernanthropus were observed. Histologic examinations indicated, both Diplectanum aequans and Lernanthropus kroyeri were present on branchial lamellae in the gills of all fishes. Lamellary edema formation, fusion of the secondary lamellae and necrosis in both primary and secondary lamellae due to parasitic irritation were determined. As a result, it was concluded that fish deaths were occurred due to the lesions formed after dense infestations of Diplectanum aequans and Lernanthropus kroyeri.
