| The weevils (Coleoptera: Curculionoidea) from South America are classsified into seven families and 28 subfamilies as follows: Nemonychidae (Rhinorhynchinae), Anthribidae (Anthribinae), Belidae (Belinae and Oxycoryninae), Attelabidae (Attelabinae and Rhynchitinae), Brentidae (Apioninae and Brentinae), Caridae (Carinae) and Curculionidae (Erirhininae, Dryophthorinae, Entiminae, Aterpinae, Gonipterinae, Rhythirrininae, Thecesterninae, Eugnominae, Hyperinae, Curculioninae, Cryptorhynchinae, Mesoptiliinae (= Magdalidinae), Molytinae, Baridinae, Lixinae, Conoderinae (= Zygopinae), Cossoninae, Scolytinae and Platypodinae). A dichotomous key for the larval stage is provided for identification of the families and subfamilies of Curculionoidea present in South... |

| The northern part of the state of Rio de Janeiro shelters many coastal lagoons, located, mostly, in the "restinga" strip that stretches from the municipality of Macaé to the municipality of Quissamã. During 1995 and 1996 samplings were made aiming to verify the diversity and density of Natantia larvae in the Imboassica, Cabiúnas and Comprida lagoons. The monthly samples were taken with a 500 µ net, in horizontal drags from a boat. In Comprida lagoon no larvae of any family of these crustaceans were found. In Cabiúnas lagoon, the autumn was the season of the year with greatest relative abundance, the larvae belonging to only one genus: Macrobrachium. In Imboassica Lagoon samples were taken in two situations related to the variation of the water level and... |

| Larva of Hemirhipus Latreille, 1825 is herein described for the first time. Larvae of Chalcolepidius porcatus (Linnaeus, 1767), from Peru, and Hemirhipus apicalis Candèze, 1857, from Argentina, are described and of Alaus myops (Fabricius, 1801), from USA (Illinois and Maryland), and A. oculatus (Linnaeus, 1758), from USA (Illinois and Florida), are redescribed and illustrated. A comparison among the known larvae in each genus is presented. An historical review and the larval characterization of five genera and fourteen species of Hemirhipini genera are also included. |

| The silver sea bream (Rhabdosargus sarba), has great commercial value in Mauritius. The species is a potential candidate for aquaculture. The sea bream, a winter spawner, was successfully induced to breed in captivity with HCG (Human Chorionic Gonadotropin) hormone injection (250 IU/kg body weight) in 1989 at the Albion Fisheries Research Centre. In 1997, the Coastal Fisheries Resources and Environment Conservation Project of Japanese International Cooperation Agency (JICA) was launched to enhance the stock of the silver sea bream in the lagoon. This species breeds under hatchery conditions during the spawning season. Annually, the hatchery-produced sea bream fingerlings, of 2.0 to 2.5 cm body length, were released in the coastal areas. The larval rearing... |

| The sea bass, Dicentrarchus labrax, has been subjected to intensive aquaculture on the Mediterranean cost for ten years. Marine fish hatcheries are key factors in the aquaculture field, and face different pathologies, especially one of viral origin (nodavirus) that could challenge their feasibility. Consequently, we have tried to provide some data on larvae and spawning stocks. Firstly, we have studied the immunoglobulins, components of the specific humoral immunity, and their role as antibodies. On adult basses, these immunoglobulins are tetrameric molecules with high molecular weight (850 kD), made of heavy (H) - 80 kD and light (L) - 26 kD chains. In the eggs, simplest forms such as monomeric or dimeric are brought to the fore; they are located under... |

| In this synthesis of nearly 30 years of research on marine fish breeding (turbot, Scophthalmus maximus; sole, Solea solea; bass, Dicentrarchus labrax and sea bream, Sparus aurata) we present the main results acquired during the three periods devoted (1) to establishing zootechnical bases of marine fish breeding in general, theme 1, (2) to developing compound feeds adapted to young stages and optimising the feeds for juveniles, theme 2, and finally (3) to studying the impact of environmental factors on the growth capacity of sea fish juveniles, theme 3. Some references relating to the preliminary work on sea fish farming are given at the end of the report as well as, for each stage of this research, articles considered as the most important. The... |

| In April 2010, crude oil was spilled from the Deepwater Horizon (DWH) oil platform for 87 days, coincident with the spawning season and recruitment of the oyster, Crassostrea virginica, in the Gulf of Mexico. Impacts of acute exposures to surface-collected DWH oil (HEWAF), dispersed oil (CEWAF) and dispersant alone (Corexit 9500A®) on planktonic larval stages of C. virginica (veliger, umbo and pediveliger) were tested in the laboratory. Exposures to HEWAF, CEWAF and dispersant were toxic to larvae impairing growth, settlement success and ultimately survival. Larval growth and settlement were reduced at concentrations of tPAH50 ranging from 1.7 to 106 μg L−1 for HEWAF and 1.1–35 μg L−1 for CEWAF, concentrations well within the range of water sampled during... |

| Ammonia results from decomposition of effluents organic matter, e.g. feed wastes and fish faeces. Its un-ionized form can be toxic because diffuses easily through fish respiratory membranes, damaging gill epithelium and impairing gas exchanges. The objective of this work was determining the 96-hour CL50 of un-ionized ammonia for newly hatched pejerrey Odontesthes bonariensis larvae. Trials were set up completely randomized design, with three different concentration of un-ionized ammonia (0.57, 0.94, and 1.45 mg L-1 NH3-N) and a control treatment (n = 3). Experimental units were 20-L, aerated aquaria stocked with 20 larvae (average weight 3.9 mg). Pejerrey larvae exposed to un-ionized ammonia during 96 hours present 50% mortality at 0.71 mg L-1 NH3-N. |

| Mussels within the subfamily Bathymodiolinae, in particular the larger Bathymodiolus species (sensu lato) thriving at cold seeps and hydrothermal vents, are among the most iconic fauna to colonize deep-sea reducing habitats globally. Fuelled by energy derived from chemosynthetic symbioses, their contribution to ecosystem productivity is conspicuous, with many bathymodioline species forming dense, extensive aggregates. Chemosymbiotic mussels play crucial roles as ecosystem engineers, both through the formation of spatially heterogeneous biogenic reefs and in redistributing reduced-fluid emissions. The notable absence of Bathymodiolinae outside of reducing ecosystems affirms their dependency on these ephemeral habitats, placing spatiotemporal constraints on... |

| To investigate dispersal and connectivity between spawning and lagoon nursery habitats of the gilthead seabream, Sparus aurata, in the Gulf of Lions (northwestern Mediterranean Sea), we modeled the potential transport of the species’ larvae between its supposed main spawning site in the region (the Planier Island) and two of its main local nursery areas (the coastal lagoons of Thau and Salses-Leucate). Passive larval drift simulations using a dispersal biophysical model showed a large variability in the possible trajectories from spawning to nursery areas and in the predicted ages for larvae arrival on the two nursery sites. The most common ages at arrival obtained in the simulations (20–60 days) are broadly consistent with previous modeling studies but... |

| Two international research cruises on board of the research vessel 'Ichthys' the first one in Aug-Sept 1971, and the second other in June-July 1972, have shown the reproduction of Thunnus thynnus, T.alalunga, Auxis thazard and Sarda in the surroundings of the Balearic Islands. The observations were made on the planctonic stages of these spp and on the physico-chemical and biological conditions of the environment. Some data were also collected on the presence of juvenile or mature stages of these fishes and on their fishery. |
