TL;DR: Five distinct morphotypes of C. laticeps, largely corresponding to different fish hosts and representing separate, yet closely related genetic lineages, have been recognised and they are characterised and confirmed the key discriminating power of traits related to the reproductive system, especially the terminal reproductive organs.
Abstract: Recent morphological and molecular data have shown that one of the most common parasites of freshwater fish in the Palaearctic Region, the cestode Caryophyllaeus laticeps (Pallas, 1781) (Eucestoda: Caryophyllidea), is highly polymorphic. Five distinct morphotypes of C. laticeps, largely corresponding to different fish hosts and representing separate, yet closely related genetic lineages, have been recognised and they are characterised in the present paper. Morphotype 1 from breams, Abramis brama (L.) (type-host) and Ballerus spp., corresponds to the original Taenia laticeps Pallas, 1781 and its neotype (paragenophore ex A. brama in Russia) is designated. This morphotype is characterised by a slender body and flabellate scolex. Morphotype 2 was found in the Macedonian vimba Vimba melanops (Heckel) and the vimba bream V. vimba (L.); it is typified by a more robust body, with most anterior extent of the vitelline follicles near the scolex and the cirrus-sac situated more anteriorly than in other morphotypes. Morphotype 3 is represented by worms from the common carp Cyprinus carpio L. that possess a cuneicrispitate scolex (having the form of a wedge with shallow indentations on anterior margin). Morphotype 4 from the common nase Chondrostoma nasus (L.) has a large, robust body and a wide scolex with numerous superficial grooves (wrinkles) in its anterior part. Morphotype 5 is represented by worms from the white-eye bream Ballerus sapa (Pallas); its typical characteristics are a festoon-like anterior margin of the scolex, the absence of vitelline follicles posterior to the cirrus-sac and the absence of a well-developed internal seminal vesicle. Discriminant analysis of 15 morphometric variables readily separated Morphotypes 3, 4 and 5 and confirmed the key discriminating power of traits related to the reproductive system, especially the terminal reproductive organs. Morphological polymorphism and the genetic divergence of different morphotypes of C. laticeps correspond to its wide spectrum of fish definitive hosts and a large distribution area that includes Europe, most of Palaearctic Asia and northern Africa.
TL;DR: The obtained results for the parasite communities of V. melanops correspond and are in close connection with dependence of the biology and ecology of the determined species of helminthes and the place of the intermediate hosts as bioindicators for the status of the studied natural freshwater ecosystems.
Abstract: Biodiversity and ecological particularities of the parasite communities of the Macedonian Vimba (Vimba melanops (Heckel, 1837)) from the Maritsa River were studied during 2013. Thirty two specimens of V. melanops were examined with standard techniques for parasites and heavy metal contamination. The purpose of this research is to represent new data for the biodiversity, prevalence, intensity and mean intensity, mean abundance of parasite communities of V. melanops from the Maritsa River. Concentration of heavy metals in fish (muscle, liver, intestines and bones), some endohelminth species as bioindicators and bottom sediments were analyzed. The obtained results for the parasite communities of V. melanops correspond and are in close connection with dependence of the biology and ecology of the determined species of helminthes and the place of the intermediate hosts as bioindicators for the status of the studied natural freshwater ecosystems. The results may be applied in the various monitoring systems for assessment and forecast of the Maritsa River condition.
TL;DR: Investigation of the actual state of the water pollution from an aspect of loading environment with heavy metals and their impact on fish, fish parasites and biodiversity of water organisms in general was accomplished and assessment of fish parasites as potential bioindicators of water pollution was made.
Abstract: Study of biodiversity of freshwater fish and parasite communities from the River Arda, southern Bulgaria characterized by heavy metal pollution was carried out. Investigation of the actual state of the water pollution from an aspect of loading environment with heavy metals and their impact on fish, fish parasites and biodiversity of water organisms in general was accomplished. Assessment of fish parasites as potential bioindicators of water pollution was made. For examinations were used standard methods and techniques. The studies, belonging to 65 specimens of fishes representing 8 species during the three seasons were presented. The dominant structures of helminth communities are characterized. The model of fish species chosen for examination of the heavy metal content in this study were the European perch, Perca fluviatilis (L., 1758) and Macedonian vimba, Vimba melanops (Heckel, 1837) of the Arda River. The contents of heavy metals (Pb, Zn, Mn and Cu) (mean concentration, bioconcentration factors) in the tissues and organs of fish species and fish parasites (Eustrongylides excisus (Jagerskiold, 1909) and Caryophyllaeus sp.) were discussed. The studies carried out could be used in various monitoring systems for screening the pollution on the water environment and the organisms inhabiting the anthropogenous ecosystems.
