Distribution and relative abundance of anchovies (Clupeiformes-engraulididae) in the Sepetiba Bay, Rio de Janeiro, Brazil

Abstract: Distribution and relative abundance of juvenile fish of the family Engraulididae in the Sepetiba Bay, Rio de Janeiro, Brazil was assessed to detect patterns of use of the shallows during their early life cycle. Two yearly cycle (March-1996 to February-1997 and March-1997 to February-1998) were studied by a total of 120 beach net samples at five sites, two of them located in the inner Bay and three in the outer Bay near to the sea limit. Six Engraulididae species were identified in two genera: Anchoa januaria, … Show more

“…Apenas adultos de C. edentulus foram capturados nos arrastos de fundo, visto que esta espécie é comum nos fundos lamosos. SILVA & ARAÚJO (2000) reportaram apenas registros ocasionais de C. edentulus em programas de amostragens de praia (margem continental) e cerco (zona central e externa da Baia, próxima das ilhas), quando comparada com A. tricolor e A. januaria, mostrando desta forma a segregação do habitat pelas espécies de manjubas na Baía.…”

“…High diversity and abundance of Engraulidae in the Sepetiba Bay suggest that some mechanisms of the resources and habitat partition occur in order to avoid competition (Silva & Araújo, 2000); they justified coexistence as result of use of different resources supplied by different areas in the bay. Species that share the same area use different strategies to explore the available food resources.…”

“…Adult and juvenile individuals dwell in estuaries and sandy beaches with low salinities. Adults may use the estuary as a migratory route to lower river reaches to spawn (Silva & Araújo, 2000) limiting their larval dispersal potential to a smaller distance when compared with marine species that spawn in more open areas. Thus, A. januaria from these two locations belong to different spawning groups, and individuals from these two reproductive groups do not have direct genetic contact since they do not tolerate high salinities (Silva & Araújo, 2000).…”
