Metazoan parasites of yellowtail kingfish, Seriola lalandi lalandi, in New Zealand: Prevalence, intensity, and site preference

摘要: The prevalence and intensity of metazoan ectoparasites on the skin gills kingfish, Seriola lalandi (Carangidae), collected from White Island (n = 32), Ranfurly Banks 7), Three Kings Islands is reported. Kingfish were host to two monogenean four copepod ectoparasite species, Benedenia seriolae, Zeuxapta Caligus lalandei, aesopus, Neobrachiella spp., Lernanthropus respectively. B. seriolae C. lalandei infect skin, whereas remaining parasites located gills. All exhibited considerable variability in infection. A few kingfish completely devoid and/or others infected by moderate numbers these species. However, all Z. seriolae. Therefore, it appears that acclimation wild east coast New Zealand's North into captivity will lead transfer both effective quarantine measures be required avoid introducing broodstock systems. site preferences aesopus also investigated. a preference for attachment lateral surfaces behind dorsal fin, but forward anal fin. displayed gill arches 2 3, particularly filaments upper regions buccal cavity. most commonly occurred arch.
