AI Article Synopsis

  • Three species of the genus Magnibursatus, previously described, are identified from marine fish, including M. skrjabini, M. bartolii sp. n., and M. minutus sp. n.
  • M. bartolii is unique for having a notably larger sinus-sac and is found in the gills and branchial chamber of its host, while M. minutus is characterized by its much smaller size compared to other species.
  • The text also provides a key to differentiate between the various species within the Magnibursatus genus and mentions their distinctions from related species.

Article Abstract

Three species of Magnibursatus Naidenova, 1969 are described from marine teleosts: M. skrjabini (Vlasenko, 1931), the type species of the genus, from the gobiid Zosterisessor ophiocephalus on the Bulgarian Black Sea coast; M. bartolii sp. n. from the sparid Boops boops off the Atlantic coast of Spain; and M. minutus sp. n. from the gobiid Neogobius eurycephalus on the Bulgarian Black Sea coast. M. bartolii differs from all other Magnibursatus species in its larger sinus-sac (length > 250 microm, width > 150 microm) and the more posterior location of testes. This species is also unusual in that it occurs in the branchial chamber and on the gills of its host. M. minutus is distinguished by the distinctly smaller dimensions of the body (length < 1000 microm, width < 200 microm), organs and eggs. These species are also distinguished from both M. caudofilamentosa (Reimer, 1971) and Tyrrhenia blennii Paggi et Orecchia, 1975. A key to the species of Magnibursatus is presented.

One of the fish species with the highest potential for aquaculture is the sharpsnout seabream, Diplodus puntazzo Cetti. Among other aspects, the development of new fish cultures requires studies of potential pathogens that may compromise survival of the fish in captivity. Moreover, both cultured and wild fish can act as sources or reservoirs of pathogens which may negatively affect other well-established cultures.

Records of derogenid digeneans in the Mediterranean and Black Sea region are scarce and tend to be restricted to a small number of host-groups, but especially to sparid fishes. This work reports on the presence of derogenine and halipegine derogenids from two sparids, Diplodus annularis (L.) and D.

In the brackish Baltic Sea, the species richness and diversity of parasite communities of three- (Gasterosteus aculeatus) and nine-spined sticklebacks (Pungitius pungitius) were investigated. The studies regarded four localities at the Schleswig-Holstein and Mecklenburg coasts, northern Germany, where salinities were between 10 and 18 per thousand. Species richness was relatively high, attaining 15 parasite species in G.

Two species of halipegine derogenids are redescribed in detail from marine fishes off Corsica. Following a study of specimens from blennies off Corsica and museum material, Tyrrhenia Paggi & Orecchia, 1975 is considered to be a synonym of Magnibursatus Naidenova, 1969, and its type-species, T blennii Paggi & Orecchia, 1975, is transferred to the latter genus as M. blennii (Paggi & Orecchia, 1975) n.
