| RESUMEN En el presente estudio se evaluó la variación estacional de la composición y abundancia de las especies de la familia Gerreidae y su relación con las variables ambientales que prevalecen en el ecosistema de manglar del estero El Conchalito, Ensenada de La Paz B.C.S. México. Los muestreos mensuales fueron realizados en la entrada del canal de mareas entre junio de 1996 y agosto de 1997. Se registraron las variables ambientales de temperatura, salinidad, oxígeno disuelto, amplitud de marea y velocidad de la corriente. La recolecta de los organismos se efectuó con una red estacionaria tipo “Flume net” colocada en la boca del canal, durante los periodos de pleamar y de acuerdo con los ciclos lunares. Se recolectó un total de 10,005 individuos con un... |

| Se describe por primera vez la especie conocida vulgarmente en inglés como "masked hamlet" con el nombre científico de Hypoplectrus providencianus spec. nov. La especie se separa claramente de sus congéneres por la coloración: cuerpo pálido, barra negra a modo de lágrima, aletas pectorales negras (o al menos con los bordes dorsales oscuros), aleta caudal oscura (o al menos con los márgenes superior e inferior negruzcos), mancha peduncular negra entre bien desarrollada a ausente. Se le conoce solamente de islas del Caribe occidental y aguas adyacentes: Providencia, cayos de Bolívar (= Courtown) y Albuquerque, Grand Cayman y Jamaica. Se presenta información sobre las otras especies del género conocidas de Colombia: H. puella, H. unicolor, H. nigricans, "tan... |

| Abstract: We present here an embracing freshwater fish inventory of the Parque Nacional dos Lençóis Maranhenses and adjacent areas, reporting 49 fish species, 33 of which were identified accurately at the species level, representing ten orders and 25 fish families that range from obligate freshwater to estuarine organisms. This number of species is much larger than two previous studies for the park, each reporting just 12 and 33 fishes occurring on freshwater environments. Among the 49 freshwater species recorded in this study, 14 are new records for the Parque Nacional dos Lençóis Maranhenses, and just one corresponds to an introduced species. Some of the 14 new records in the Parque Nacional dos Lençóis Maranhenses, cited above, as well as some of the 16... |

| Researcher since 1974 at CNEXO (National Centre for Exploration of the Oceans), then at IFREMER (French Institute for Exploitation of the Sea), I have at the same time brought to the work of researching the dynamics of exploited ichthyologic populations actions for enhanced improvement and transfer of knowledge to help managers and stakeholders administer these resources and restore them if needed. This activity led me to play a double role: that of the expert who is asked to set up "a truth judgment" on a given subject or according to a specific question, and that of the scientist faced with the judgment of his peers who strives not to go against his knowledge (i.e., that which is subject to the criticism of the scientific community). This change of... |

| Se presenta información descriptiva y ecológica de nueve especies del género Coryphopterus (Pisces: Gobiidae) colectadas en los arrecifes, principalmente coralinos, del Caribe colombiano (incluyendo la Isla de Providencia). Se incluye además una-clave para identificar las especies. La más común en los muéstreos fue C. personatus (67%), seguida por C. eidolon (52%), C. dicrus (21%), C. glaucofraenum (27%); C. thrix (19%), C. tortugae (10%), C. lipernes (9%), C. hyalinus (4%) y C. alloides (3%). Se observaron diferencias regionales importantes en relación con su presencia y abundancia. Las poblaciones del Caribe continental colombiano tienden a ser más pigmentadas que las de regiones norteñas del Atlántico oeste trópica!, probablemente a causa de la... |

| The systematics and taxonomy of poeciliid fishes (guppies and allies) remain poorly understood despite the relative importance of these species as model systems in the biological sciences. This study focuses on testing the monophyly of the nominal poeciliine tribe Heterandriini and the genus Heterandria, through examination of the morphological characters on which the current classification is based. These characters include aspects of body shape (morphometrics), scale and fin-ray counts (meristics), pigmentation, the cephalic laterosensory system, and osteological features of the neurocranium, oral jaws and suspensorium, branchial basket, pectoral girdle, and the gonopodium and its supports. A Maximum Parsimony analysis was conducted of 150 characters... |

| Abstract This paper presents a checklist of the reef fish fauna of the Anchieta Island State Park, a no-take zone in which no extractive activities are allowed, in Ubatuba, Southeastern Brazil. Data was obtained between 2011 and 2013, mainly through underwater observations with snorkelling and SCUBA, and secondarily using scientific fishing (trawling). Published and unpublished data were also verified and compiled. A total of 103 reef fish species, distributed in 78 genus and 50 families was recorded. Haemulidae was the richest family (n=7 species), followed by Epinephelidae (n=6), Pomacentridae, Carangidae and Tetraodontidae (n= 4 each). Haemulon was also the most speciose genera (n=5), followed by Stegastes, Acanthurus and Mycteroperca (n=3 each).... |

| The chaenopsine blennies are an homogeneous group which may be considered a subfamily of the Clinidae, since the existing evidence is not enough to give them familial status. The subfamily includes eight genera: Mccoskerichthys, Coralliozetus, Acanthemblemaria, Ekemblemaria, Emblemaria, Hemiemblemaria, Lucayablennius, and Chaenopsis. The nominal genera Protemblemaria and Emblemariopsis are herewith considered synonyms of Coralliozetus, since they share two derived characters: small size and sexual dimorphism in the color of the head, and are rather similar in several other characteristics. The división of the West Indian Zoogeographical Province made by Briggs (1974) is unnatural, since the fish fauna of Belize, Florida and the Bahamas is very similar. I... |
