| For the fourth consecutive year, the fishing returns of the shelly season of the roads of Brest are analyzed. For the black Scallop, principal species currently exploited, the goal is to know the evolution of the fisheries. For the shell St Jacques, season 86-87 saw a light improvement of the captures due to a good recruitment during summer 84. In the first chapter the general conditions of the unfolding of the countryside are treated, in the following are analyzed the captures of black scallop then of shell St Jacques. In appendix the data of effort and production of the other species during the season appear. |

| ABSTRACT The use of traps is extremely important in several types of ecological studies, and may assist in the capture of individuals in areas that are difficult to access. In the present study, we compared the effectiveness of wooden (Schramm) versus "Tomahawk" traps to capture Salvator merianae (Duméril & Bibron, 1839) lizards. The study was conducted in Eldorado do Sul, Rio Grande do Sul, Brazil. Field data were collected from August 2013 to March 2015, during the reproductive period of the species. The study involved two types of baited traps: i) "Tomahawk", made of galvanized steel; and ii) Schramm, a wooden trap. The capture rate of the Schramm wooden traps was 1.63 individuals/day, and of the "Tomahawk" was 0.36 individuals/day. These results... |

| Cet atlas interactif de la pêcherie palangrière de l'océan Indien a été réalisé dans la suite du projet IOSSSESPADON. Il synthétise d’une part, l'historique de la pêche palangrière de l'océan Indien depuis les années 1950 (efforts de pêche et captures d'espadon – Xiphias gladius par période de 5 ans et par rectangle statistique de 5°) et d’autre part, l'évolution de l'activité de la flottille palangrière réunionnaise depuis 1994 (efforts de pêche, captures et rendements pour les principales espèces ciblées). Pour le volet relatif à la Réunion, les données sont présentées : 1- annuellement par rectangle statistique de 5° (1994 – 2014), 2- annuellement ou par trimestre par rectangle statistique de 1° -2006 – 2014). Cet outil interactif permet une... |

| A research programm on the marine green turtle Chelonia mydas nesting on the two major reproduction sites for the species in the Indian Ocean, conducled over last 15 years, included intensive tagging programm. Processing of these lagging data provides estimations of adult female populations {or each site and season from two independent methods. First classical method is the ratio of total number of nests produced over a define time on the mean individual number of nests by female during the same time (November, December, January). The computed mean individual number ranges from 3 to 3.5 obtained over 2 to 3 months. The second method is the multiple capture-recapture method (JOLLY, 1965; SEBER, 1965; MANLY, 1984). Il is an original tentative of applying... |

| Introduction : Since 1978, new measures to better manage lobster fisheries were implemented in the Celtic Sea within the context of Community regulations. Meshing, in particular, was set at 60mm, but many owners, in order to maintain sufficient leeway vis-à-vis the regulations and to avoid administrative hassles adopted at the outset fish meshing at 70mm, even 80mm. Certain habits aiming to compensate for the losses due to these increases were established: Adoption of better-performing trawls, increase in the secondary catch and enlargement of the fisheries. At the same time, especially because of strong demand from international bodies, OEM and especially EEC, knowledge about the lobster spread and more reliable assessments were achieved, the main problem... |

| International trade law is very clear: national security concerns take precedent over any commitments in trade agreements. In response to the terrorist attacks in New York and Washington on September 11, 2001, the United States and other countries have been putting in place new anti-terrorist measures, many of which will act to inhibit international trade. As with any measure that inhibits international trade, these new measures will provide an economic benefit to domestic vested interests in importing countries. Guarding against the possibility of terrorist acts is by nature a speculative activity, and it is difficult to refute the need for the anti-terrorist measures put in place by governments. As a result, trading partners may be frustrated by what... |

| Au cours de l'année 1966, la pêche du merlu au filet maillant se développe sur les côtes françaises de l'Atlantique. Les premiers mois, ses rendements bien supérieurs à ceux du chalut lui attirent un grand nombre d'artisans dans presque tous les ports du Golfe de Gascogne. Son développement est rapide, mais très vite, les apports diminuent en qualité et en quantité. Ce type de pêche subit alors une désaffection aussi brusque que l'a été son extension. Treize mois après son introduction, cette technique est presque entièrement abandonnée. Nous avons pensé qu'il serait intéressant d'en retracer l'historique, d'étudier la composition de ses captures et l'évolution de ses rendements. |

| Acoustic deterrent devices could be an appealing solution to tackle accidental cetacean by-catches in pelagic trawls or in fishing net gears. The bibliographical data on two species (Harbour porpoise and bottlenosed dolphin) have been analyzed in terms of audiogram, discomfort noise level that could lead to behavioural changes, sensory fatigue, and threshold for permanent hearing injuries. It is possible, on the basis of the above data, to characterize an efficient annoyance sound threshold which is not harmful to the species to be protected. Taking into account the properties of the sound waves propagation in the marine environment and according to the required range, the minimal amplitude of the repulsive sound to emit is proposed. Accordingly, the... |

| The role of vitamin C on physiological responses of matrinxã (Brycon amazonicus) submitted to air exposure was analyzed. Nine hundred fish (70.15 g) were distributed in fifteen 500 l boxes (60 fish.box-1) and fed five rations (treatments): Control (no vitamin C); T100 (100 mg); T200 (200 mg); T400 (400 mg) and T800 (800 mg of vitamin C kg.ration-1). Each ration was offered to fish of three boxes during 60 days before the stress challenge that consisted of exposing fish to air for two minutes. Samplings were carried out for 5, 15, 30 and 60 minutes after the air exposure. Blood was collected for glucose, cortisol, total protein, sodium, chloride, hematocrit, hemoglobin determination, and white and red cell count. Liver was removed for hepatosomatic index... |

| Carbon capture and storage (CCS) technologies remove carbon dioxide from flue gases for storage in geologic formations or the ocean. We find that CCS is technically feasible and economically attractive within the range of carbon policies discussed domestically and internationally. Current costs are about $200 to $250 per ton of carbon, although costs are sensitive to fuel prices and other assumptions and could be reduced significantly through technical improvements. Near-term prospects favor CCS for certain industrial sources and electric power plants, with storage in depleted oil and gas reservoirs. Deep aquifers may provide an attractive longer-term storage option, whereas ocean storage poses greater technical and environmental uncertainty. Vast... |
