| Adults of the palaemonid prawn Palaemon macrodactylus Rathbun, 1902 were reported for the first time from the southwestern Atlantic waters. Males and ovigerous females were collected in Mar del Plata harbor (38 degree 03' S; 57 degree 31' W), Argentina; larvae obtained from one of the collected females were reared in the laboratory until the juvenile stage. The geographical range of P. macrodactylus was previously restricted to the Pacific Ocean: it was originally described in Japan and has been reported as an invasive species in the western coast of USA in the 1950's and in Australia in the 1970's. Recently, this prawn has been also reported from European waters. |

| Mytella charruana (d’Orbigny) (Mollusca: Bivalvia: Mytilidae) in Cartagena Bay, Colombia. High densities of the bivalve Mytella charruana were found for the first time in the Bay of Cartagena, Colombian Caribbean, during an antifouling field assay carried out during the second semester of 2008. This species reached average densities of 13400 individuals m-2 on underwater manmade substrates. Size range was between 0.5 and 3.6 cm with an average length of 1.95 cm. Mytella charruana is an avid surface colonizer, monopolizes underwater substrates and reaches cover areas close to 100 % generally as an epibiont. |

| Los organismos no nativos son frecuentemente transportados por las actividades humanas y accidental o premeditadamente introducidos, dando al ambiente un matiz diferente del original. Cuando las condiciones son favorables, los organismos recién llegados pueden reproducirse y asentarse con éxito. Sin embargo cuando las interacciones de los organismos recién llegados con el nuevo ambiente y las comunidades asentadas son destructivas, la introducción se conoce como invasión (Aguilar-Perera y Tuz-Sulub, 2010). Los cambios en la biodiversidad marina pueden dar lugar a alteraciones de las comunidades o poblaciones existentes y a la pérdida o extinción de especies e incluso provocar la invasión de especies nuevas.Amphibalanus reticulatus aunque es nativa... |

| The host specificity and population dynamics of <i>Anguillicola crassus</i> in a number of paratenic hosts were investigated. Various freshwater fish species were sampled monthly (March 1990 to March 1991) from the Kolenhaven (Albertcanal, Genk, Belgium) and examined for L<sub>3</sub>-larvae of <i>Anguillicola crassus</i>. Sixteen species were found to be infected: all the physoclist species examined (<i>Gymnocephalus cernua, Lepomis gibbosus, Ictalurus nebulosus, Stizostedion lucioperca, Gasterosteus aculeatus, Oreochromis niloticus</i> and <i>Perca fluviatilis</i>) and those physostome species of which a sufficient number could be examined to detect the infection (<i>Gobio gobio, Leuciscus... |

| In late 2001 and early 2002, a dichotomous species of Codium appeared colonizing the low intertidal and shallow subtidal bottoms of Caldera Bay, northern Chile (27° 03 S, 70° 51 W). Due to the ecological and economic impact the species is having in Caldera Bay and its potential spread along the Chilean coastline, we studied the taxonomic identity of the species and examined its relationships with other dichotomous species of Codium reported for temperate Pacific South America. Morphological analyses suggest that the seaweeds from Caldera Bay belong to Codium fragile (Suringar) Hariot. Not only is there strong agreement in internal and external morphological characters, but among all the species reported for Peru and Chile, this is the only one exhibiting... |

| The scyphozoan Phyllorhiza punctata von Lendenfeld, 1884 (Mastigiidae), known only from Indo-Pacific waters prior to the 1950s, is today found far from its original distribution, probably due to human activities. First seen in 1955 in Brazilian waters, medusae were found in southern and southeastern coasts, disappearing (at least as a medusa) in the early 1960's. Another population was found in the late 1990's, in the state of Bahia, and again in late 2001, many sightings were reported along the coasts of Paraná and Santa Catarina (25º20'S, 48º12'W to 27º26'S, 48º22'W). A large summer bloom, followed by decline and disappearance in winter and spring, occurs every year since then. The reasons for this recent mass occurrence are unknown. Despite few... |

| Exotic (introduced) species are a growing problem in ports worldwide and comprise the most important impacts in marine ecosystems. Periodic monitoring to detect introduced species is extremely important for effective population control. Here we sampled ascidian species near the port of Paranaguá for a taxonomic study of this fauna to attempt to detect introduced species. Larval stages in ascidians are short-lived, and dispersal is restricted to small distances, and so ascidians are very good bioindicators for exotic introductions due to ship transport. Four locations were sampled within Paranaguá Bay (Ilha das Cobras, Pier Tenenge, Ilha do Mel and Ilha da Galheta) and one location outside of the bay (Parque dos Meros). Information for the nearby fauna and... |

| Achatina fulica, known as Giant African Snail (GAS), was introduced in Brazil as a substitute for the European escargot, Helix aspersa maxima. However, its cultivation was abandoned and the mollusk became an invasive species, found throughout Brazil and causing damage to health and the environment. In this context, this study analyzed the knowledge of the population about the damage caused by GAS, seeking to reveal a regional scenario on this issue. This exploratory and cross-sectional study was conducted by means of a questionnaire applied to 150 people, which obtained sociodemographic characteristics of respondents and specific responses about the knowledge and handling of GAS. The results showed that most of the respondents know the snail and are... |

| ABSTRACT The exotic land gastropod Ovachlamys fulgens (Gude, 1900), aka the jumping snail, was registered in Eldorado city, Misiones province, constituting the first documented record of that species in Argentina-and for all of South America as well. Identities of the individuals were confirmed through morphological examination, and by a DNA sequencing of the cytochrome oxidase subunit I gene. DNA sequences for the mitochondrial 16S-rRNA and the nuclear 18S-rRNA genes were also obtained from the morphologically-confirmed specimens to gain insights into the genetic background of this species in Argentina, and as additional markers for enhancing the rapidity of identification by governmental authorities who are responsible for managing the presence of exotic... |

| ABSTRACT Schyzocotyle acheilognathi is a tapeworm cestode commonly found in native freshwater fishes from Asia. This cestode has low host specificity and for that reason it has been registered parasitizing more than 200 cultured and wild fish species, besides amphibians, reptiles and birds from different regions of the world. With a high pathogenic potential, S. acheilognathi may cause mortalities in highly infected fish. In South America, Schyzocotyle was reported in Cyprinus carpio from a Brazilian fish farm at the municipality of Cornélio Procópio, northern Paraná State and from the natural environment in C. carpio from Neuquen River, Patagonia, Argentina. So far, there has been no report of this parasite in South American native fishes. Herein we... |

| Abstract: This study focus on an inventory of the ichthyofauna of the Una river, a tributary of the Paraíba do Sul river, located in the region of Paraíba do Sul River Valley, in the State of São Paulo. Sampling was carried out in three sampling areas along the channel of the Una river between April 2016 and March 2017. For the collection of fish specimens, was used angling, fyke nets, cast nets, dragnets and hand nets. A total of 1.534 specimens were collected, which corresponds to five different orders, 14 families, 26 genera and thirty species. The study revealed that the most significant number of reported species are from the orders Siluriformes and Characiformes. The Characidae family was the most representative concerning the wealth of species and... |
