Cotylogaster basiri Siddiqi & Cable, 1960 (Aspidobothrea: Aspidogastridae) in Pogonias cromis (Linnaeus, 1766) (Perciformes: Sciaenidae): first report from Brazil.
Up until now, there have been few studies of the helminth fauna of Brazilian populations of Pogonias cromis. In North America, P. cromis is known to be a definitive host of Cotylogaster basiri, although there have been no reports of any species of Cotylogaster infecting fish in Brazil.

متن کاملRadiocarbon From Nuclear Testing Applied to Age Validation of Black Drum, Pogonias cromis
-Radiocarbon < 14C >in the world's oceans increased sharply between 1950 and 1970 as a result of the atmospheric testing of nuclear weapons. Through comparison with the 14C time series reconstructed from atmospheric measurements and marine carbonates, Kalish, in 1993, used the 14C concentration measured in fish otolith cores as a means of confirming the annulus-based age estimates for some Sout...
متن کاملOccurrence of Fasciola hepatica (Linnaeus, 1758) in capybara (Hydrochoerus hydrochaeris) (Linnaeus, 1766) in Minas Gerais, Brazil Ocorrência de Fasciola hepatica (Linnaeus, 1758) em capivara (Hydrochoerus hydrochaeris) (Linnaeus, 1766) em Minas Gerais, Brasil
Fasciola hepatica is a parasite that affects the hepatic ducts of several species of domestic and wild vertebrates, causing huge economic losses to livestock rearing worldwide. Reports on occurrences of F. hepatica in capybaras are an important epidemiological aspect of this disease, since these rodents can be a source of contamination for other animals and humans. In the present study, conduct...
متن کاملAge, Growth, and Mortality of Black Drum, Pogonias cromis, in the Chesapeake Bay Region
-we used otolith ageing to describe the population dynamics of black drum, Pogonias cromis, collected over a three-year period from the Chesapeake Bay region's commercial and recreational fisheries. Black drum average age, total length, and weight were 26 years, 109.5 cm, and 22.1 kg respectively. The oldest fish was 59 years and fish older than 50 years were present in the catch from 1990 to 1...
