In this study, seasonal numerical abundance of the critically endangered Atlantic goliath grouper Epinephelus itajara was estimated by conducting scuba dive surveys and calculating sightings‐per‐unit‐effort ( SPUE ) at three sites in southern Brazil. Seasonal differences size reproductive condition captured or confiscated specimens were compared. The differed significantly with season, increasing late spring peaking during austral summer months. A significant effect observed number fish...
The Brazilian-endemic greenbeack parrotfish, Scarus trispinosus Valenciennes, 1840, is the largest herbivorous reef fish in South Atlantic. Following sharp decline of large carnivorous fishes, parrotfishes (Labridae: Scarinae) were progressively targeted by commercial fisheries Brazil, resulting a global population 50% for S. . Most its remnant concentrated Abrolhos Bank, where present study was conducted. We novel information on age, growth and reproductive cycle , based 814 individuals...
(Lichtenstein, 1822), is the largest reef fish in western Atlantic Ocean, reaching up to 2.5 meters long and > 400 kg (BULLOCK et al., 1992). The species matures at 5-8 years with a maximum age of 37 Some characteristics goliath grouper that make them particularly vulnerable overfishing include their large body size, slow growth, high longevity, late maturity, formation predictable seasonal spawning aggregations (SADOVY; EKLUND, 1999). Consequently, has suffered sharp population declines...
Neobenedenia melleni (MacCallum, 1927) (Monogenea) is a pathogen widely spread in marine teleost cultures around the world. The present paper recorded this parasite species Goliath grouper Epinephelus itajara for first time Brazil. use of freshwater bath control was successful grouper.
Many aspects of sex change in reef fishes have been studied, including behavior and social organization. However, gonad histology remains the most robust way to identify sexual patterns fishes. Some uncommon tissues remain poorly described, such as accessory gonadal structures found species from Gobiidae family, which are rare other bony This is first report testicular gland Gramma brasiliensis for Grammatidae family. Between April 2011 February 2012 eighty specimens were collected during...
Nesting is a common behaviour associated with reproduction in several taxa. Nevertheless, this important parental care rarely reported for reef-associated fish. The present study provides the first description of bird-like complex nesting endangered basslet (Gramma brasiliensis). Males were observed building nests using macroalgae thalli around holes and depressions, coralline substrate. Algae used to camouflage nest entrance form cushioned bed egg laying. critical aspect reproductive...
