Drought-associated absence of alien invasive anchorworm, Lernaea cyprinacea (Copepoda: Lernaeidae), is related to changes in fish health

Welicky, Rachel L.; De Swardt, Jurgen; Gerber, Ruan; Netherlands, Edward C.; Smit, Nico J. (Elsevier, 2017)

Recently, Mozambique tilapia (Oreochromis mossambicus Peters, 1852) were listed on the IUCN Red List as near-threatened as their populations are at risk due to hybridization. Another factor that potentially contributes to ...

Molecular assessment of three species of Anilocra (Isopoda, Cymothoidae) ectoparasites from Caribbean coral reef fishes, with the description of Anilocra brillae sp. n.

Welicky, Rachel L.; Hadfield, Kerry A.; Sikkel, Paul C.; Smit, Nico J. (Pensoft, 2017)

A morphological review and molecular characterization of Anilocra haemuli Bunkley Williams & Williams, 1981, were completed using specimens collected from Haemulon flavolineatum Desmarest, 1823 (French grunt) and Epinephelus ...

Redescription and molecular characterisation of the fish ectoparasite Anilocra capensis Leach, 1818 (Isopoda: Cymothoidae), with description of six new species of Anilocra Leach, 1818 from Africa

Welicky, Rachel L.; Smit, Nico J. (BioMed Central, 2019)

Background: Anilocra capensis Leach, 1818 is the only named species of Anilocra Leach, 1818 from South Africa. Anilocra is a large genus (>40 species) with high levels of diversity reported from the Caribbean and Indo-West ...

Diurnal activity patterns of the temporary fish ectoparasite, Gnathia africana Barnard, 1914 (Isopoda, Gnathiidae), from the southern coast of South Africa

Welicky, Rachel L.; Sikkel, Paul; Smit, Nico J.; Ferreira, Maryke L. (Cambridge Univ Press, 2018)

Gnathiid isopods are one of the most common fish ectoparasites, and are found in both temperate and tropical oceans. On coral reefs, gnathiids are most active at dusk and dawn, and contribute significantly to trophic ...

Hooked on you: shape of attachment structures in cymothoid isopods reflects parasitic strategy

Baillie, Charles; Welicky, Rachel L.; Hadfield, Kerry A.; Smit, Nico J.; Mariani, Stefano (BMC, 2019)

Background Parasite attachment structures are critical traits that influence effective host exploitation and survival. Morphology of attachment structures can reinforce host specificity and niche specialisation, or even ...

Understanding growth relationships of African cymothoid fish parasitic isopods using specimens from museum and field collections

Welicky, Rachel L.; Malherbe, Wynand; Hadfield, Kerry A.; Smit, Nico J. (Elsevier, 2019)

Cymothoid isopods are a diverse group of ectoparasites of fish species, and are particularly conspicuous as they are large and attach to the body surface, mouth, and gill chamber of fish hosts. These parasites transition ...
