| Several coastal fish use the estuarine habitat during a part of their life cycle. These sites are considered good for the reproductive activity, as well as for the growth of larvae and juveniles. Concerning the Gerreidae, however, many studies reveal that most species leave the estuaries to reproduce at sea. At Guaratuba Bay, southern Brazil, this family is represented by three genera and five species, which make an important fraction of the local assemblage. The present study investigated the populational structure and breeding habits of three Eucinostomus species, in order to know what relationship exists between them and the mangrove. It was found that the Guaratuba mangrove represents a transitory habitat for the life cycle of the Eucinostomus species.... |

| El urohial es un hueso impar de origen dérmico, ubicado en el centro de la mandibula inferior de los peces teleósteos y constiyuye un elemento fundamental en el mecanismo de apertura bucal. El estudio comparativo del hueso urohial en los Gerreidae americanos, sustenta la idea de que dicha estructura manifesta formas distintivas que pudieran ser de gran utilidad para la diferenciación taxonómica a nivel de géneros y de especies. La presente contribución ofrece una descripción de las características que distinguen la morfología del hueso urohial de cinco especies selectas representativas de cuatro géneros de la familia Gerreidae en América: Diapterus (D. brevirostris), Eucinostomus (E. dowii), Eugerres (E. lineatus y E. mexicanus) y Gerres (G. cinereus). |

| Diapterus rhombeus (Cuvier, 1829) is one of the most common Gerreidae species in the estuarine region at the Guaratuba Bay, Southern Brazil. Based on studies developed between July, 1993 and January, 1997, it was observed that its presence in the mangrove area is not regular: the smallest individuais are more abundam during late summer and in autumn, and the largest ones during spring and early summer. Its diet comprises plant material and invertebrates, specially polychaets. The morphological aspects of the gonads, the monthly changes on the Condition Factor, and lhe monthly distribution of the individual size groups, suggest that this population spawns during the spring, out the estuarine region. The smaller individuais use the mangrove area of Guaratuba... |
