“…Several studies have described the influence of environmental factors on the distribution of fish species (MARSHALL; ELLIOTT, 1998;ARAÚJO et al, 2002;RUEDA;DEFEO, 2003). In this study, environmental factors measured did not affect the fish community, or distribution over the months.…”

Ichthyofauna as an environmental quality indicator of the Bertioga Channel, São Paulo (Brazil)The aim of this study was to investigate the ichthyofauna structure in the region of the north outfall of the Bertioga Channel (São Paulo, Brazil) and the possible effects of the environmental quality loss. The samples were collected in a monthly basis, from September to December 2005, at two oceanographic stations with an otter-trawl. The fish fauna structure was evaluated by ecological indicators and the environmental quality evaluated by the ABC analysis and the Estuarine Fish Communities Index (EFCI). A total of 1553 individuals from 50 species were sampled. Ariidae and Sciaenidae amounted to 60 % and Cathorops spixii represented 36 % of all specimens collected. The highest richness and ecological diversity were recorded in December, while the highest numerical abundance was found in October. The majority of the species were represented by juveniles. The cluster analysis and canonical correspondence analysis showed a consistent and clear difference between the sampling stations, and the abiotic factors analyzed (temperature, depth and salinity) do not seem to have influence on the community structure. The ABC analysis suggested a moderate disturbed environment and the EFCI allowed classifying the area as "poor", due to the 12 metrics analyzed, concerning the reduction of the species diversity, composition and abundance, and modifications in the nursery function and trophic integrity of the area.

“…Anchoa januaria showed indications of preference for estuarine areas such as lower rivers reaches (Araújo et al, 2002). Sergipense & Sazima (1995) also found A. januaria in higher abundance in sites in the inner zone between 1983 and 1985.…”

“…Influences of environmental variables on fish occurrence were assessed by grouping fishes numbers in four intervals of temperature in degree Celsius (1 (Teer Braak, 1986). This is one of the best methods for direct gradient analysis in community ecology (Rodriguez & Lewis, 1997;Araújo et al, 2002) and is widely used to assess environmental influences on fish occurrence.…”

Habitat selection by anchovies (Clupeiformes: Engraulidae) in a tropical bay at Southeastern Brazil

et al. 2008

View full text Add to dashboard Cite

Distribution of anchovies (Clupeiformes, Engraulidae) was described in the Sepetiba Bay, a coastal area of Southeastern Brazil, to assess eventual mechanisms of habitat selection. Two fish sampling programmes were accomplished; one using beach seine (1998/2000) to catch juveniles in sandy beaches, and the other, using seines (1999/2000) to catch adults in deeper bay areas. Six species representing 4 genera were recorded: Anchoa tricolor, Anchoa januaria, Anchoa lyolepis, Cetengraulis edentulus, Engraulis anchoita and Lycengraulis grossidens. Anchoa tricolor and A. januaria were the most abundant species, with the former peaking in the outer bay, while the latter peaking in the inner bay. Adults A. tricolor are target of heavy commercial fisheries in the bay during Spring-Summer, while E. anchoita, an abundant species in the continental shelf, was occasionally caught in large numbers during the Autumn. The habitat selection, by using two different bay areas, was developed by the two most abundant species, a probable mechanism to enable their coexistence.
A distribuição de manjubas (Clupeiformes, Engraulidae) foi descrita na Baía de Sepetiba, uma área costeira do Sudeste do Brasil, para determinar eventuais mecanismos de seleção de habitat. Dois programas de amostragem foram realizados; um usando arrasto de praia (1998/2000) para captura de juvenis, e outro, usando arrasto de fundo (1999/2000) para captura de adultos. Seis espécies representadas por quatro gêneros foram capturadas: Anchoa tricolor, Anchoa januaria, Anchoa lyolepis, Cetengraulis edentulus, Engraulis anchoita e Lycengraulis grossidens. Anchoa tricolor e A. januaria foram as espécies mais abundantes, com a primeira ocorrendo principalmente na zona externa da baía, enquanto a segunda com maior abundância na zona interna. Adultos A. tricolor são alvo de intensas pescarias comercial na baía durante a Primavera-Verão, enquanto E. anchoita, uma abundante espécie na plataforma continental, foi ocasionalmente capturada em grande numero durante o Outono. A seleção de hábitat, através do uso de diferentes áreas da baía, foi desenvolvida pelas duas espécies mais abundantes, um provável mecanismo para permitir a coexistência

“…The Sciaenidae was also the most diverse and abundant family in the Guanabara Bay, Rio de Janeiro State, especially due to large amounts of Micropogonias furnieri in the central area of the study (Rodrigues et al, 2007). In the Sepetiba Bay, Rio de Janeiro State, fish assemblages were not strongly dominated by sciaenids but also included Ariidae and Gerreidae as dominant groups (Araújo et al, 2002), although a spatial repartition was found and Micropogonias furnieri was one of the dominant species in the inner zone of the bay while Ctenosciaena gracilicirrhus was one of the dominant species in the outer zone (Azevedo et al, 2007). Off the coast of São Sebastião, São Paulo State, Muto et al (2000) registered sciaenids as the most prominent family in number of species, abundance and weight and stated that Ctenosciaena gracilicirrhus, Paralonchurus brasiliensis and Cynoscion jamaicensis dominated the catches.…”
