Balanço ácido-base do sangue do jacaré, Caiman crocodilus yacare, Pantanal Sul, Brasil.
Provedor de dados: 14
Autores: CAMPOS, Z. M. da S.
O balanço ácido-base do sangue do jacaré-do-Pantanal foi estudado em área de rio intermitente, Pantanal Sul. O sangue dos jacarés adultos foi coletado na estação fria e quente. O pH do sangue dos jacarés depois da captura variou entre 6,6 a 7,0 e não foi relacionado com a massa corporal na faixa de 3,8 a 38,5 kg. A temperatura cloacal não afetou o pH do sangue. O estresse de captura causou pouca mudança no pH do sangue e de outros gases. Isso pode ser explicado pelo tamanho menor dos jacarés do Pantanal comparados com outros crocodilianos.

Analyse de la pecherie de petoncle noir et de coquille Saint-Jacques de la rade de Brest
Provedor de dados: 5
Autores: Merrien, A.
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.

Etude comparative des coefficients de conversion utilisés pour estimer le poids vif des captures des flottilles de pêche de l'Union
Provedor de dados: 5
Autores: Caillart, Benoït; Borel, Gidas; Merrien, Claude.
Conversion coefficients are the factors used in estimating the live-weight equivalent of fish caught. Live weight is the only measure used in catch statistics, being the basis in particular for monitoring the drawdown of quotas and estimates of the state of stocks. The study looked first at how figures on catches in live-weight equivalent are gathered, validated and calculated in three Member States, namely Denmark, France and the United Kingdom. These three countries employ related methods involving the database storage of sales data together with details of the presentation of the fish. The information in logbooks is mainly used as a cross-check on the sales data. If sales data are not available, logbook details are entered raw in the catch databases....

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...

The aim of the project "rationalization of biological sampling for stock assessment of marine fisheries in the bay of Biscay" is to perform statistical methods and computer programs allowing to test prognoses and diagnoses based on estimates of fishing mortalities, recruitments, yields per recruit, and the "gain-loss" function. The project gathers the laboratories of the community working on the Bay of Biscay fisheries, namely - Santander in Spain (1. E. 0) - La Rochelle and Lorient in France (IFREMER). A descriptive study has been carried out. The prepared documents contain a description of the procedures used to collect the information, by each of the laboratories involved, on: - landings - biological samplings. More comprehensive data have been gathered...

Trois saisons de pêche de la truite de mer
Provedor de dados: 5
Autores: Deschamps, Gerard; Miossec, Dominique; Pannier, Thierry.
The research programme developed within in the framework of the project study of the Paluel site allowed us to highlight, near the drainage channel of the Durdent, a sea trout fishery using fixed nets in the area of the swaying of the tides. This activity, very much in use in the eastern English Channel and along the southern shoreline of the North Sea, not only for catching certain amphibiotic species but also species that are strictly of the sea, represents a sizeable cause of the mortality rate for salmonid populations during their coastal migrations. The studies begun on this fishery in 1980 have as their goal to assess the size of the salmonid catches near the site, especially of sea trout, and to acquire more complete knowledge of the catch, biology...

La pêche du merlu au filet maillant sur les côtes françaises de l'Atlantique et plus particulièrement à La Rochelle
Provedor de dados: 5
Autores: Quero, Jean-claude; Meriel-bussy, Pol.
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.

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).

Le répulsif à cétacés : performances acoustiques requises
Provedor de dados: 5
Autores: Le Gall, Yves; Origne, Laurent; Scalabrin, Carla; Morizur, Yvon.
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...

Captures of the coffee berry borer (CBB) Hypothenemus hampei (Ferrari) were assessed in traps in the field. IAPAR designed traps [plastic bottles (2 L) lured with methanol:ethanol (1:1) in a vessel] were placed either at 0.5, 1.0 and 1.5m high from the ground or simultaneously tested in the 2004 fructification season. Traps placed at the three heights trapped 5.5 times more CBB than the others, mostly at the traps placed at 0.5 m (75%). Treatments using the IAPAR designed trap placed at 1.2 m high; IAPAR trap with a white plastic plate above (IAPAR modified I) at 1.2 m high; IAPAR at 0.5 m high and two additional vessels at 1.0 and 1.5m high (IAPAR modified II) and T-163 trap [three red plastic cups (300 ml) and a red plastic plate as a cover] lured with...

Autores: Ould Taleb Ould Sidi, M.M.
Cette étude montre que les captures des espèces de petits pélagiques dans la Zone Economique Exclusive Mauritanienne de 1991 à 1999 fluctuent et se diversifient sous l'effet de la variation des abondances, des changements de stratégie et de l'arrivée de nouvelles flottilles dans la zone. Les captures des sardinelles sont multipliées par 3 suite à l'arrivée des flottilles de l'Union Européenne et au report sur ces deux espèces d'une partie de l'effort de pêche traditionnellement exercé sur les chinchards. Les captures de l'anchois ont connu une augmentation encore plus remarquable suite à l'entrée de la flottille de Saint Vincent et Grenadine et au report d'une partie de l'effort exercé auparavant sur d'autres espèces.

Homeland Security and the Rules of International Trade
Provedor de dados: 31
Autores: Kerr,   William A.
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...

Prospects for Carbon Capture and Storage Technologies
Provedor de dados: 31
Autores: Anderson,   Soren T.; Newell,   Richard G.
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...

Environmental Tariffs: Will They Be Captured by Protectionists?
Provedor de dados: 31
Autores: Kerr,   William A.
Environmental tariffs appear to be a politically necessary part of the climate change policies that are emerging in many countries. The appeal of level playing field arguments is seductive and difficult to dispute. Environmental policy makers, however, may be naïve, because they fail to account for the potential of trade policy mechanisms and institutions to be captured by traditional vested interests seeking economic protection. The exact structures and institutional frameworks for environmental tariffs are often left vague by environmental policy makers, making them easy targets for protectionists. Environmental tariffs appear to be particularly vulnerable to capture given the complexity of production and the embryonic stage of the science of measuring...

The Public Management of Risk: Separating Ex Ante and Ex Post Monitors
Provedor de dados: 31
Autores: Hiriart,   Yolande; Martimort,   David; Pouyet,   Jerome.
When a firm undertakes risky activities, the conflict between social and private incentives to implement safety care requires public intervention which can take the form of both monetary incentives but also ex ante or ex post monitoring, i.e., before or after an accident occurs. We delineate the optimal scope of monitoring depending on whether public monitors are benevolent or corruptible. We show that separating the ex ante and the ex post monitors increases the likelihood of ex post investigation, helps prevent capture and improves welfare.

Approaches to capturing the Black and White Tegu Salvator merianae (Squamata: Teiidae)
Provedor de dados: 103
Autores: Vieira,Renata C.; Oliveira,Arthur S. de; Fagundes,Nelson J.R.; Verrastro,Laura.
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 &amp; 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...

Trapping, restraint and clinical-morphological traits of wild canids (Carnivora, Mammalia) from the Brazilian Cerrado
Provedor de dados: 104
Autores: Curi,Nelson H. de A.; Talamoni,Sônia A.
This article presents a simple, safe and efficient method for the capture and chemical immobilization of three species of wild canids from the Serra do Cipó National Park region, in the Cerrado biome of Southeastern Brazil. Morphological measurements and anesthesia data obtained during the captures are also described. Such data are essential due to the necessity for invasive research for monitoring programs, clinical cases analysis, and ecological or epidemiological investigations in wild or captive Neotropical canid populations.

Physiological responses of matrinxã (Brycon amazonicus) fed different levels of vitamin C and submitted to air exposure
Provedor de dados: 36
Autores: Abreu,Janessa Sampaio de; Urbinati,Elisabeth Criscuolo.
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...
