Submitted by Alberto Vieira (martins_vieira@ibest.com.br) on 2017-10-18T19:57:10Z No. of bitstreams: 1 273742.pdf: 9671615 bytes, checksum: 90f3be274b8863e761d3dc5d719240ef (MD5) / Made available in DSpace on 2017-10-18T19:57:10Z (GMT). No. of bitstreams: 1 273742.pdf: 9671615 bytes, checksum: 90f3be274b8863e761d3dc5d719240ef (MD5) Previous issue date: 1981-09-20 / Como resultado de sete anos de estudos (na Baía de Guanabara, RJ, Brasil, e áreas adjacentes) foram coletados 2523 exemplares de Engraulidae representados por seis espécies: Engraulis anchoita Hubbs & Marini, 1935; Anchoa lyolepis (Evermann & Marsh, 1902); Anchoa tricolor (Agassiz, 1829); Anchoa januaria (Steindachner, 1879); Cetengraulis edentulus (Cuvier, 1829); Anchoviella perfasciata (Poey, 1860). O desenvolvimento de E.anchoita, A.lyolepis, A.tricolor e c.edentulus que é descrito e ilustrado, assim como as informações disponíveis sobre as duas outras espécies, contribuem para a identificação destes peixes. Observações sobre a alimentação, reprodução, distribuição e parasitas são apresentadas. A importância da Baia de Guanabara no ciclo de vida destes peixes também é discutida. / As result of a seven years study (at Guanabara Bay, RJ, Brazil, and nearby localities) a total sample of 2523 specimens of the Engraulidae was collected, represented by six species: Engraulis anchoita Hubbs & Marini, 1935; Anchoa lyolepis (Evermann & Marsh, 1902); Anchoa tricolor (Agassiz, 1829); Anchoa januaria (Steindachner, 1879); Cetengraulis edentulus (Cuvier, 1829); Anchoviella perfasciata (Poey, 1860). The development of E.anchoita, A.lyolepis, A.tricolor and C.edentulus is described and illustrated in detail and the available information on the remaining other two species is given as a contribution to the identification of these fishes. Observations on nutrition, reproduction, distribution and parasites are presented. The role of Guanabara Bay in the cited fishes life-cicle is discussed.
