Detection of Ectoparasite Lernaea cyprinacea (Copepoda: Lernaeidae) on some Cypriniformes Fish from the Mediterranean Region of Turkey

Abstract

Lernaea cyprinacea L.,1758 is a lernaeid copepod species usually known as anchor worm. It is usually reported as having a wide range of host susceptibility. Parasites belonging to the genus Lernaea can have serious deleterious effects on their freshwater fish hosts. Parasites belonging to the genus Lernaea, it has been reported from several host fish species to date in Turkey. Mediterranean region of Turkey supports a rich diversity of Cypriniformes fish fauna, with a high percentage of endemic species. This study reports the infection of L. cyprinacea on some native and alien Cypriniformes fish in the Mediterranean region of Turkey. Barbus xanthos, Alburnus baliki, Pseudophoxinus zekayi and Pseudorasbora parva were found as new host records for L. cyprinacea.

Molecular and morphological identification of Lernaea spp. in Cyprinid fishes from two districts in Yogyakarta, Indonesia

“…Water conditions may have affected the heterogeneity in the degree of infection. The pH, oxygen, temperature, and salinity values were within the anticipated range [38,39]. Along with stocking density, climatic factors, and environmental conditions play a significant role in the prevalence of Lernaeid ectoparasites at various geographic locations [4].…”

Prevalence and Histopathological Effects of Parasitic Copepod Lernaea Cyprinacea in Estuarine Fishes From Mediterranean Region of Turkey, With a New Host Record

“…Widespread in Turkey, the copepod ectoparasite Lernaea cyprinacea is considered a possible threat to the endemic fish stocks, such as Alburnus baliki (Innal, 2020). In Karpuzçay Creek Estuary, the highest infection prevalence value was found in Chelon ramada (7.5%) and the lowest in Alburnus baliki (3.3%).…”

“…Difference values for prevalence and intensity of infection depend on various factors, such as season, sample size, feeding habits, sex ratio, length range or physico-chemical parameters (Barson et al 2008;Hossain et al 2018Innal, 2020Khalid et al 2021).…”

“…The Antalya bleak was studied concerning the morphometric measurements (Mangit, 2014), age and growth parameters (Innal and Gülle 2019) or phylogeography (Bektas et al 2020), however with respect to ichthyoparasitofauna, data remain scarce. The copepod Lernaea cyprinacea was detected before on A. baliki in Karpuzçay Creek (Innal, 2020). Also, the acanthocephalan Pomphorhynchus laevis specimens were identified in this host in streams discharging into Antalya Bay (Aydoğdu et al 2011).…”

“…This ectoparasite has been found infesting over 40 freshwater fishes in Turkish inland waters, predominantly Cypriniformes, including the following species: Alburnus baliki, Barbus xanthos, Capoeta capoeta, Carassius carassius, Carassius gibelio, Cyprinus carpio, Chondrostoma nasus, Chondrostoma beysehirense, Cyprinion macrostomus, Oxynoemacheilus anatolicus, Pseudophoxinus egridiri, Pseudophoxinus burduricus, Pseudorasbora parva, Pseudophoxinus zekayi, Squalius cephalus and Tinca tinca (Koyun and Atici 2018;Innal, 2020).…”
