Distribuição e ciclo de vida das espécies de peixes mais abundantes da laguna de Marapendi, Rio de Janeiro, Brasil

Abstract

<abstract language="eng">Monthly sampling from march 1981 to april 1983 using beach seines, cast nets and gill nets indicated six species, Xenomelaniris brasiliensis, Brevoortia pectinata, Geophagus brasiliensis, Gerres aprion, Genidens genidens and Achirus lineatus, as the most abundant fishes in the Marependi Lagoon, Rio de Janeiro, BraziL The species presented a long reproductive period and the recruitment distributed throughout the year. Analysis of the mean catch per unit effort in relation to month, sampling areas, and environmental factors along with analysis of the length frequency distribution by depth strata indicated that the spatial distribution, related to depth and occurrence of submerged aquatic vegetation seem to be the main factors regulating the species distribution. Alteration of the environmental conditions in the lagoon due to the opening of the Marapendi channel in 1984 caused significative modification in the distribution and abundance patterns of the main species. The impact of these alterations in the Marapendi Lagoon fish community has yet to be determined

Spatial and temporal distribution patterns of the silver mojarra Eucinostomus argenteus (Perciformes: Gerreidae) in a tropical semi‐enclosed bay

“…argenteus into the bay probably occurs during the larval or juvenile stage and is more likely during the latter (Godefroid et al ., ; Castro et al ., ). In Brazil, spawning and recruitment periods overlap in coastal areas and occur throughout the year, but peak in the summer (December to February) and between winter and spring (July to October) (Matsuura & Nakatani, ; Barbieri et al ., ; Araújo & Santos, ). Recruitment in Guanabara Bay shows a similar pattern and the main events (July to August 2006 and May to June 2007) occurred during the periods of low precipitation, suggesting that the entry of young juveniles into the bay is linked to periods of lower discharge from the estuary.…”

“…The silver mojarra Eucinostomus argenteus Baird & Girard 1855 is found in coastal waters of the eastern Pacific, from the U.S.A. to Peru, and in coastal waters of the western Atlantic Ocean, from the U.S.A. to Brazil (Gilmore & Greenfield, ). Eucinostomus argenteus is the most common species of the genus in Brazilian waters and the second most abundant species in Sepetiba Bay, Rio de Janeiro, and is among the 10 most abundant species in Guaratuba Bay, Paraná, Brazil (Barbieri et al ., ; Araújo & Azevedo, ; Spach et al ., ; Azevedo et al ., ). Even though few studies have reported on the abundance of E .…”

Reproductive biology of the flatfish Etropus crossotus (Pleuronectiformes: Paralichthyidae) in the Paranaguá Estuarine Complex, Paraná State, subtropical region of Brazil

“…According to Patiño & researchers that work with estuarine species in the tropical region of Brazil (Barbieri et al, 1991;Gomes et al, 1999;Pessanha & Araujo, 2001). According to Lowe-McConnell (1999), and corroborating the presumptions above, the reproduction period occurs at different times along the The results found for both sexes of E. crossotus, with the obtainment of individuals with mature, spawned/spermiated and immature gonads, consistently support the assertion that the species uses the study area for reproduction and recruitment.…”

Effects of a red tide on the structure of estuarine fish assemblages in northeastern Brazil

“…When the curves of the dominance of abundance and richness per rank species are plotted, the biomass curve seems to exceed the abundance. Atherinella brasiliensis is a typical species that forms shoals in shallow estuarine regions (BARBIERI et al, 1991;ANDREATA et al, 1997ANDREATA et al, , 1997HOSTIM-SILVA et al, 1995;PESSANHA et al, 2000;RAMOS and VIEIRA, 2001). With numerical dominance of small-sized species, an inversion of the curves may occur, with the biomass curve being exceeded by the abundance curve.…”

“…FAVARO et al (2009) reported this species as being common in intertidal environments and it is considered important for the trophic balance in coastal environments (DUNCAN and SZELISTOWSKI, 1998;SCHULTZ et al, 2002). Atherinella brasiliensis is a typical species that forms shoals in shallow estuarine regions (BARBIERI et al, 1991;ANDREATA et al, 1997ANDREATA et al, , 1997HOSTIM-SILVA et al, 1995;PESSANHA et al, 2000;RAMOS and VIEIRA, 2001). These two species were the most abundant during the red tide.…”
