Os Argulídeos (Crustacea: Branchiura) da Amazônia Brasileira, 2. Aspectos da ecologia de Dolops geayi Bouvier, 1897 e Argulus juparanaensis Castro, 1950. ()

Abstract: INTRODUÇÃOA subclasse Branchiura é formada por crustáceos ectoparasitas de peixes com aproximadamente 130 espécies conhecidas. O gênero Argulus é o que possui o maior número de representantes, cerca de 110, é cosmopolita e ocorre tanto em água doce quanto salgada. Os demais são dulcícolas e tem ocorrência restrita a determinadas regiões, tais como: Dolops, endêmico ao continente sul americano com onze espécies conhecidas, exceto, D. ranarum que só ocorre na África; o Chonopeltis é formado por sete espécies e t… Show more

Some composition and structural patterns were here detected in the parasite community of A. ocellatus in the different basins in Brazil, including: (a) dominance of G. asota and Gussevia astronoti Kritsky, Thatcher and Boeger 1989; (b) dominance of ectoparasite species with crustacean infracommunities more diverse than other ectoparasites; (c) overdispersion of ectoparasites and endoparasites, (d) interspecific associations in the ectoparasite infracommunities, specifically a combination of generalist and specialist parasites that should contribute to host population control (e.g.…”

“…Piranhas represent a large percentage of the number of individuals and the total biomass of Osteichthyes where they live (Mago-Leccia, 1970). Because of that, many studies have been conducted on the interaction between piranhas and their crustacean ectoparasites (Malta, 1982b;Malta & Varella, 1983;Carvalho et al, 2003). …”

“…Causam uma série de danos a seus hospedeiros, através de ações espoliadoras e traumatizaçào de tecidos com seus órgãos de fixação. Quando parasitam a cavidade bucal e branquial diminuem a capacidade respiratória, com a retirada de sangue, destruição dos tecidos, interrupção da circulação sangüínea, oclusão dos vasos aferentes, formação de coágulos e hipertrofia dos filamentos, freqüentemente causam sérios prejuízos em cultivos de peixes (Ringuelet, 1943;Lemos de Castro, 1950;Kabata, 1970Kabata, , 1985Malta, 1981;1982a;1982b;1983;1984;Malta & Varella, 1983).…”
