    Uncommon records of fishes may evidence local or global changes of fish composition resulting from environmental modifications or anthropic activities. Significant records of uncommon marine fishes, including migrant, non-native, cryptic, rare and threatened species, collected in French waters or by French vessels in European waters, observed by scuba divers or walkers, are reported for the year 2018. They include first, new, rare and unusual records for the following 52 species: Hexanchus griseus, Squatina squatina, Gymnura altavela, Acipenser sturio, Acipenser gueldenstaedtii, Dalophis imberbis, Nemichthys curvirostris, Eurypharynx pelecanoides, Maulisia mauli, Maulisia microlepis, Sagamichthys schnakenbecki, Melanostomias bartonbeani, Astronesthes niger*, Leptostomias gladiator*, Chlorophthalmus agassizi, Magnisudis atlantica, Evermannella balbo, Regalecus glesne, Luvarus imperialis, Raniceps raninus, Fistularia petimba*, Trigla lyra, Lepidotrigla dieuzeidei, Micrenophrys lilljeborgii, Howella atlantica*, Pomatomus saltatrix, Serranus cabrilla, Caranx crysos, Seriola rivoliana, Trachinotus ovatus, Lobotes surinamensis, Sarpa salpa, Liza ramada, Pseudoscopelus altipinnis*, Trachinus draco, Parablennius pilicornis, Parablennius ruber, Buenia affinis, Buenia jeffreysii, Chromogobius zebratus, Didogobius splechtnai, Gammogobius steinitzi, Gobius couchi, Gobius kolombatovici, Lebetus sp., Speleogobius trigloides, Thorogobius macrolepis, Vanneaugobius dollfusi, Siganus rivulatus*, Lepidocybium flavobrunneum, Hyperoglyphe sp. et Pegusa cf. nasuta*, among which seven, marked with an asterisk (*), represent additions to the Checklist of the marine fishes from metropolitan France and one, N. curvirostris, is a first record for the Mediterranean.

    Despite many studies focusing on the invasive occurrence of Poecilia reticulata, the guppy, one of the most widely introduced freshwater fish species due to aquaria release and mosquito control, there are little and conflicting information about its natural distribution range. Based on extensive field surveys carried out in the Brazilian Amazon in the past ten years, information present in literature, online databases and museum records, P. reticulata is considered to be naturally absent from the Amazon Basin, from the Amapá and Pará territories in northern Brazil, and from French Guiana and Suriname. Poecilia reticulata records are few and noncontiguous for this entire region, generally associated with disturbed and polluted environments nearby populated areas. This pattern contrasts with a wider distribution expected by freshwater flooded savannah dwelling species, especially in the Guiana Shield coastal rivers, known for an ichthyofaunal similarity gradient pattern. The few records in the Amazon Basin are not attributed to low sampling effort but probably rather to the resilience and biotic resistance of pristine Amazonian habitat assemblages towards invasive species. The southernmost natural limit of P. reticulata distribution range was tentatively delimited as a region between the Essequibo River in the Guiana and the Orinoco Delta in Venezuela, where the species naturally occurs. Diagnostic characters distinguishing P. reticulata from close congeners that naturally occur in the region are presented.

    Fishing activity is a primary sector of great socioeconomic importance for the archipelago of Cabo Verde (eastern-central Atlantic), and has played a relevant role in strengthening food security, reducing poverty, job creation, balance of payments equilibrium and Gross Domestic Product. So, this review was needed to make small-scale fisheries visible in a Developing Island Country with a fast-growing tourist industry. The aims of this study were to make an updated description of small-scale fisheries and their target species, then to point out new or emerging fisheries and propose some pilot actions and challenges to sustainable fisheries development, as a research-based baseline for future regional plans. The difficulties faced today by this sector are: a high degree of unpredictability, seasonality, perishability of the fishery product, risks associated with the activity, and low educational level of most operators. Fishing vessels vary enormously in size and on-board equipment. Biodiversity of resources targeted by these multispecific fisheries involves some 180 species. Due to the large size of Cabo Verde EEZ, its fishing resources are diverse and some reach exploitable biomasses. Tuna fishing in principle is the resource with the greatest potential. Emphasis should be placed on the development of added-value products and the establishment of a quality control system. Possible fisheries development should be planned as a smallscale or artisanal scheme and further cooperation projects will be useful for the country.
