Summary Ectoparasites, attaching mainly to the fins or gills, are a particularly conspicuous part of the parasite fauna of marine fishes. In particular the dominant copepods, have received much interest due to their effects on host populations. However, still little is known on the copepod fauna on fishes for many localities and their temporal stability as long-term observations are largely absent. The aim of this project was two-fold: 1) to deliver a current inventory of ectoparasitic copepods in fishes in the southern Wadden Sea around Texel and 2) to compare the current parasitic copepod fauna with the one from 1968 in the same area, using data published in an internal NIOZ report and additional unpublished original notes. In total, 47 parasite species have been recorded on 52 fish species in the southern Wadden Sea to date. The two copepod species, where quantitative comparisons between 1968 and 2010 were possible for their host, the European flounder (Platichthys flesus), showed different trends: Whereas Acanthochondria cornuta seems not to have altered its infection rate or per host abundance between years, Lepeophtheirus pectoralis has shifted towards infection of smaller hosts, as well as to a stronger increase of per-host abundance with increasing host length.

  • APPENDIX 1 Classified List of Fishes Mentioned in the Text, with Scientific and Common Names
    APPENDIX 1 Classified list of fishes mentioned in the text, with scientific and common names. ___________________________________________________________ Scientific names and classification are from Nelson (1994). Families are listed in the same order as in Nelson (1994), with species names following in alphabetical order. The common names of British fishes mostly follow Wheeler (1978). Common names of foreign fishes are taken from Froese & Pauly (2002). Species in square brackets are referred to in the text but are not found in British waters. Fishes restricted to fresh water are shown in bold type. Fishes ranging from fresh water through brackish water to the sea are underlined; this category includes diadromous fishes that regularly migrate between marine and freshwater environments, spawning either in the sea (catadromous fishes) or in fresh water (anadromous fishes). Not indicated are marine or freshwater fishes that occasionally venture into brackish water.

SUMMARY: Parasites are recognised as an excellent source of information on the distribution of their hosts. Here, the mac- roparasite fauna of 20 species of Pleuronectiformes belonging to five different families and inhabiting the Portuguese coast was investigated and compared with that known in four other areas (the North Sea, north Northeast Atlantic, Mediterranean Sea and Northwest African coast) in order to determine (1) their zoogeographical pattern and (2) the role of the Portuguese coast as an intermediate biogeographic province. Macroparasites infecting Pleuronectiformes sampled along the Portuguese coast were collected using standard parasitological techniques, whereas data on those in the other four areas were obtained from the literature, rendering a total of 73 macroparasite species.
