No. of bitstreams: 2 Tese mestrado pós banca - Amanda Karen Silva de Souza.pdf: 1405799 bytes, checksum: 68b408327a4b2f27d252e91f9498cc17 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5) Previous issue date: 2018-02-19 / Conselho Nacional de Pesquisa e Desenvolvimento Científico e Tecnológico - CNPq / Were collected and examined 63 specimens of Pellona castelnaeana captured in the Catalão lakes complex. The mean fish length was 28.5 cm ± 6.4 and the mean weight was 328.3 g ± 208.5. Were collected and identified 477 specimens of parasites. 14 Monogenoidea; 01 Digenea, 39 Acanthocephala, 382 Nematoda, 43 Copepod, 01 Isopoda and 01 Argulus and 01 Dolops. The Monogenoidea Mazocraeoides makrodemas parasitized the gills filaments, the Digenea Austrodiplostomum compactum the eye; the Acanthocephala Neoechinorhynchus (Neoechinorhynchus) sp. n. the intestine; the Nematoda Anisakis sp. the surface of the liver, stomach and intestine; the Copepoda Acusicola pellonidis the gills filaments; the Branchiura Argulus chicomendesi and Dolops bidentata the body surface; and Isopoda, Braga patagonica the gill cavity. Anisakis sp. was the species with the highest prevalence (38%) followed by N. (N.) sp. n. (20.63%). All others species occurred with low prevalence. Eighty percent of the parasite community of P. castelnaeana was dominated by Anisakis sp., followed by Neoechinorhynchus (Neoechinorhynchus) sp. (9.6%). The fauna of species parasites of P. castelnaeana was formed by a secondary species and seven satellites species. Only one parasite species presented secondary distribution, Anisakis sp. with prevalence of 38%. The species of Monogenoidea, Acanthocephala, Copepoda and Nematoda presented aggregate distribution. Anisakis sp. presented a negative correlation between total length and abundance. Only for Anisakis sp. "p" was significant (p ≤ 0.05). / Foram coletados e examinados 63 exemplares de Pellona castelnaeana, capturados no complexo de lagos do Catalão. O comprimento médio dos peixes foi de 28,5cm ± 6,4 e o peso médio 328,3g ± 208,5. Foram coletados e identificados 477 espécimens parasitos. Monogenoidea 14 indivíduos; Digenea 1, Acanthocephala 39, 382 Nematoda, Copepoda 43, 01 Isopoda e 2 Branchiura. O Monogenoidea Mazocraeoides makrodemas parasitava as brânquias; o Digenea, Austrodiplostomum compactum o olho; o Acanthocephala, Neoechinorhynchus (Neoechinorhynchus) sp. n. o intestino; o Nematoda, Anisakis sp. a superfície do fígado, o estômago e o intestino; o Copepoda, Acusicola pellonidis os filamentos branquiais; as espécies de Branchiura, Argulus chicomendesi e Dolops bidentata a superfície do corpo; o Isopoda, Braga patagônica a cavidade branquial. Anisakis sp. foi a espécie com a maior prevalência (38%) seguida de Neoechinorhynchus (N.) sp. (20,63%). Todas as outras espécies ocorreram com baixa prevalência. Oitenta por cento da comunidade parasita de P. castelnaeana foi dominada por Anisakis sp., seguida por Neoechinorhynchus (Neoechinorhynchus) sp. (9,6%). A fauna de espécies parasitas de P. castelnaeana era formada por uma espécie secundária e sete satélites. Apenas uma espécie parasita apresentou distribuição secundária, Anisakis sp. com prevalência de 38%. As espécies de Monogenoidea, Acanthocephala, Copepoda e Nematoda apresentaram distribuição agregada. Anisakis sp. apresentou correlação negativa entre o comprimento total e a abundância. Somente para Anisakis sp. “p” foi significativo (p ≤ 0,05).
