Inventory and comparison of abundance of parasitic copepods on fish hosts in the western Wadden Sea (North Sea) between 1968 and 2010

A conspicuous part of the parasite fauna of marine fish are ectoparasites, which attach mainly to the fins or gills. The abundant copepods have received much interest due to their negative effects on hosts. However, for many localities the copepod fauna of fish is still poorly known, and we know little about their temporal stability as long-term observations are largely absent. Our study provides the first inventory of ectoparasitic copepods on fish from the western Wadden Sea (North Sea) based on field data from 1968 and 2010 and additional unpublished notes. In total, 47 copepod parasite species have been recorded on 52 fish host species to date. For two copepod species parasitizing the European flounder (Platichthys flesus), a quantitative comparison of infection levels between 1968 and 2010 was possible. Whereas Acanthochondria cornuta did not show a change in the relationship between host size and infection levels, Lepeophtheirus pectoralis shifted towards the infection of smaller hosts, with higher infection levels in 2010 compared to 1968. These differences probably reflect the biology of the species and the observed decrease in abundance and size of flounders during the last decades. The skin-infecting L. pectoralis can probably compensate for dwindling host abundance by infecting smaller fish and increasing its abundance per given host size. In contrast, the gill cavity inhabiting A. cornuta probably faces a spatial constraint (fixed number of gill arches), thus limiting its abundance and setting a minimum for the host size necessary for infections

Taeniacanthus dentatus sp. nov., a copepod parasite of the fish Bembrops caudimaculata Steindachner

Bassett-Smith (1898) was the first to describe a piscicolous taeniacanthid, Irodes tetradontis (Bassett-Smith), from the Indian region. However, taeniacanthid copepods of the genus Taeniacanthus Sumpf, 1871, have never been reported from Indian fishes until quite recently, when eight species of taeniacanthids belonging to five different genera, including one new genus and seven new species, were described. by Pillai (1963) from South Indian fishes. Of these, three belonged to the genus Taeniacanthus iind were new. Herein is described a fourth species, T. dentat

Copépodes e isópodes parasitos de nove espécies de peixes marinhos (Osteichthyes) do litoral do Estado do Rio de Janeiro, Brasil

Entre fevereiro de 2009 a junho de 2012, 368 espécimes de nove espécies de peixes marinhos (Osteichthyes) coletados ao longo da costa do Estado do Rio de Janeiro (21° - 23° S, 41° - 45° W), foram necropsiados para estudar sua fauna parasita de Copepoda e Isopoda. Foram identificadas 11 espécies de copépodes e três espécies de isópodes parasitos. Sendo coletados 852 espécimes de copépodes e quatro de isópodes. O mais prevalente e abundante dentre os crustáceos parasitos foi Taeniacanthus lagocephali Pearse, 1952, enquanto Coryphaena hippurus Linnaeus, 1758 foi a espécie de hospedeiro com a maior diversidade de espécies de ectoparasitos. Os gêneros Ceratothoa Dana, 1852 e Mothocya Hope, 1851 são registrados pela primeira vez para o Brasil neste estudo

Indonesian marine fish parasite biodiversity

The Indonesian fish parasite fauna is evaluated from literature since 1840, 678 new parasite records, 621 parasite and 315 host species. New species descriptions, records and methods demonstrate a higher biodiversity than thought (different geno- for similar morphotypes). Most former records originate from commercial or cultured fish. The current knowledge in a host-parasite checklist enables risk evaluation for aquaculture and fishery industries. The knowledge of the local species phylogeny enables conclusions on worldwide zoogeography and is discussed with a parasite checklist from Hawaii

Alien species in the Mediterranean Sea by 2012. A contribution to the application of European Union's Marine Strategy Framework Directive (MSFD). Part 2. Introduction trends and pathways

More than 60 marine non-indigenous species (NIS) have been removed from previous lists and 84 species have been added, bringing the total to 986 alien species in the Mediterranean [775 in the eastern Mediterranean (EMED), 249 in the central Mediterranean (CMED), 190 in the Adriatic Sea (ADRIA) and 308 in the western Mediterranean (WMED)]. There were 48 new entries since 2011 which can be interpreted as approximately one new entry every two weeks. The number of alien species continues to increase, by 2-3 species per year for macrophytes, molluscs and polychaetes, 3-4 species per year for crustaceans, and 6 species per year for fish. The dominant group among alien species is molluscs (with 215 species), followed by crustaceans (159) and polychaetes (132). Macrophytes are the leading group of NIS in the ADRIA and the WMED, reaching 26-30% of all aliens, whereas in the EMED they barely constitute 10% of the introductions. In the EMED, molluscs are the most species-rich group, followed by crustaceans, fish and polychaetes. More than half (54%) of the marine alien species in the Mediterranean were probably introduced by corridors (mainly Suez). Shipping is blamed directly for the introduction of only 12 species, whereas it is assumed to be the most likely pathway of introduction (via ballasts or fouling) of another 300 species. For approximately 100 species shipping is a probable pathway along with the Suez Canal and/or aquaculture. Approximately 20 species have been introduced with certainty via aquaculture, while >50 species (mostly macroalgae), occurring in the vicinity of oyster farms, are assumed to be introduced accidentally as contaminants of imported species. A total of 18 species are assumed to have been introduced by the aquarium trade. Lessepsian species decline westwards, while the reverse pattern is evident for ship-mediated species and for those introduced with aquaculture. There is an increasing trend in new introductions via the Suez Canal and via shipping.The research leading to these results was partly supported by funding from the European Community’s Seventh Framework Programme ([FP7/2007-2013]) under grant agreement n° 287600 - PERSEUS project (Policy-oriented marine Environmental Research for the Southern European Seas).
