Age, growth, reproduction and management of Southwestern Atlantic's largest and endangered herbivorous reef fish, Valenciennes, 1840.

The Brazilian-endemic greenbeack parrotfish, Valenciennes, 1840, is the largest herbivorous reef fish in the South Atlantic. Following the sharp decline of large carnivorous reef fishes, parrotfishes (Labridae: Scarinae) were progressively targeted by commercial fisheries in Brazil, resulting in a global population decline of 50% for . Most of its remnant population is concentrated in the Abrolhos Bank, where the present study was conducted.

First record of Neobenedenia "melleni"-like species (Monogenea: Capsalidae) in Goliath grouper Epinephelus itajara in Brazil.

Neobenedenia melleni (MacCallum, 1927) (Monogenea) is a pathogen widely spread in marine teleost cultures around the world. The present paper recorded this parasite species in the Goliath grouper Epinephelus itajara for the first time Brazil. The use of freshwater bath for parasite control was successful for the Goliath grouper.
