Popis | Largemouth bass, Micropterus salmoides (Lacepéde, 1802) were sampled from four provinces (Eastern Cape, EC; North West, NWP; KwaZulu-Natal, KZN; Western Cape, WC) in South Africa to assess for parasite diversity and community composition. Morphological evaluation of the sampled parasite specimens provided evidence for the first record of five monogeneans from the family Ancyrocephalidae: Clavunculus bursatus (Mueller, 1963), Onchocleidus dispar (Mueller, 1936), Onchocleidus furcatus (Mueller, 1937), Onchocleidus principalis (Mizelle, 1936) and Syncleithrium fusiformis (Mueller, 1934) from the African continent. Community composition differed between localities. Clavunculus bursatus were only sampled from the EC and KZN, O. dispar and O. principalis were only sampled from the EC and WC, O. furcatus was only sampled from the NWP and KZN populations and S. fusiformis only from KZN. Prevalence was 100% at all sites, except in the WC where one of the two localities had a prevalence of 93%. Data from this study support the enemy release hypothesis as many of the parasites reported from the native range of M. salmoides were not collected. |
