Digenea (Trematoda) of Micropogonias furnieri (Desmarest) (Perciformes, Sciaenidae) from Rio Grande do Sul, Brazil

Abstract

ABSTRACT. Digcnca (Trcmaloda)

Community ecology of the metazoan parasites of white croaker, Micropogonias furnieri (Osteichthyes: Sciaenidae), from the coastal zone of the State of Rio de Janeiro, Brazil

“…The highest values of dispersion of C. australe cystacanths detected in M. furnieri from the State of Rio de Janeiro, are in agreement with the results obtained by Pereira Jr. and Neves (1993) and Sardella et al (1995) in M. furnieri from Brazil and Argentina, respectively; and by Cezar and Amato (1998) …”

“…These ecological differences might explain the highest parasitism level by larval stages of cestodes and acanthocephalans in M. furnieri from the coastal zone of Rio Grande do Sul, recorded by Oliveira (1985), Pereira Jr. (1993, and Pereira Jr. and Neves (1993). M. furnieri from Rio Grande do Sul has higher population density (sometimes in 8:1 rate) than the white croaker populations from the coastal zone of the State of Rio de Janeiro (Vazzoler 1991, Haimovici & Umpierre 1996.…”

“…Several taxonomic papers on the parasites of M. furnieri from Brazil were published: Amato (1983a, b), Fabio (1988), Fernandes and Goulart (1992) , Alves and Luque (2000a) on digeneans and aspidobothreans; Kohn et al (1989), Alves and Luque (2000a) on monogeneans; Oliveira (1985), São Clemente (1986a), Pereira Jr. (1993 and Alves and Luque (2000a) on cestodes ;Pereira Jr. and Neves (1993) and Alves and Luque (2000a) on acanthocephalans ;Pereira Jr. and Costa (1996), Alves and Luque (2000a) on nematodes. Additional taxonomic records of parasites of M. furnieri in the South American Atlantic Ocean were made by Suriano (1966Suriano ( , 1975 from Argentina, and Vicente et al (1989) from Venezuelan coastal zone.…”

“…Studies on quantitative aspects of the parasites of M. furnieri from the Brazilian coastal zone were restricted to larval stages of trypanorhynch cestodes and acanthocephalan (São Clemente 1986b, Pereira Jr. 1993, Pereira Jr. & Neves 1993. Recently, Luque (1999, 2000b) made preliminary quantitative studies, at the parasite infrapopulation level, in adult and juvenile M. furnieri from the State of Rio de Janeiro.…”

Digenea and acanthocephala of elasmobranch fishes from the southern coast of Brazil

“…In Brazil these acanthocephalans occurred in teleost fishes: Corynosoma sp. in Pomatomus saltator from the coast of the State of Rio de Janeiro and C. australe in Micropogonias furnieri from the coast of the State of Rio Grande do Sul (Rego et al 1983, Pereira Jr & Neves 1993. The morphology of the other Corynosoma sp.…”
