A new mini box corer for sampling muddy bottoms in antarctic shallow waters BABT
Echeverría,Carlos Alejandro; Lavrado,Helena Passeri; Campos,Lúcia; Paiva,Paulo Cesar de.
A new Mini Box Corer (MBC-GEAMB) was developed for bottom sampling in Antarctic shallow waters down to 100 m depth from a small vessel. It consists of a detachable stainless steel box with a total sampling area of 0.0625 m², and a closing arm with a detachable blade without an external frame. MBC allowed stratified bottom sampling and good quality samples comparable to those obtained through diving. A comparison between the MBC-GEAMB and a 0.056 m²van Veen grab (VV) was undertaken for the benthic macrofaunal composition in Admiralty Bay, King George Island (Antarctica). MBC and VV samples were taken from three depths (20, 30 and 60m) in two sites. Total densities sampled with the MBC were up to 10 times higher than those obtained with van Veen grab. VV...

A sampling strategy and methodology for assessment and monitoring of Mediterranean small-scale fisheries ArchiMer
Farrugio, Henri; Le Corre, Gildas.
In order to reach a quantitative assessment of the Mediterranean small-scale fisheries one of the main problems is to evaluate in space and time the elementary fishing efforts and yields of every component and their corresponding variations. These elements are essential for the evaluation of global production and fishing effort, the monitoring of which is of paramount interest for the study of the fisheries and exploited resource dynamics. This paper presents a methodology based on the statistical principles of so-called "stratified random sampling" which we have developed in an attempt to solve this problem. The collection of data is achieved in the field by a team of investigators which operates within a space-time stratification of the study area. The...

A transboundary study of the pelagic fish stocks of southern OceanDocs
Krakstad, Jens-Otto; Amaro, Aristóteles P. da S.; Shigwedha, Vaino.
The main objectives of the survey were the following: • To map the distribution and estimate the abundance of the most commercially important pelagic species in the Namibia-Angola transboundary area (15°50-19°00’), following the survey design utilized in Angolan waters (6 n.mi spacing between transect lines), with special emphasis on the two horse mackerel Cunene horse mackerel (Trachurus trecae) and Cape horse mackerel (Trachurus capensis), sardine “Pilchard” (Sardinops sagax) and other small pelagic species, including anchovy (Engraulis capensis) and round herring (Etrumeus whiteheadi). • To map the distributions and estimate the abundance of the same species in central Namibia south to Dune Point (20°15’ S), following the established survey design with...

Acteurs et processus impliqués dans la dynamique de la pêche sportive au Sénégal : Cas de Dakar et de la Petite Côte OceanDocs
Manel, C. J. P..
Promue depuis les années 1970 pour booster le tourisme, la pêche sportive sénégalaise a connu de grands moments avec ses titres de champion du monde en 2002 et 2003. Cette percée au niveau mondial n’a pas permis, pour autant, le développement de l’activité qui reste peu connue de beaucoup de sénégalais. La présente étude tente d’identifier les différents acteurs ainsi que la structuration de l’offre de pêche sportive au sein des structures qui la vendent en tant que produit principal ou de diversification, et voir ainsi son importance. Pour cela, elle s’est fondamentalement basée sur l’offre touristique. Une enquête menée auprès des établissements d’hébergement touristique (EHT), des centres et clubs de pêche sportive a permis de mettre en exergue...

Aeromycological study at the intensive care unit of the "Dr. Manuel Gea Gonzalez" General Hospital BJID
Ríos-Yuil,José Manuel; Arenas,Roberto; Fernández,Ramón; Calderón-Ezquerro,María; Rodriguez-Badillo,Raymundo.
INTRODUCTION: An aeromycological study verifies the presence and quantifies the concentration of fungal propagules in the air. It is very important in the hospital setting because of the increasing numbers of immunosuppressed and severely ill patients. The objective of this study was to determine the concentration of fungi in the air of the intensive care unit (ICU) of "Dr. Manuel Gea González" General Hospital. METHODS: This is a descriptive, observational cross-sectional study. Air samples were obtained with a single stage Thermo-Andersen Viable Particle Sampler (Thermo Electron Corporation -Massachusetts, U.S.A.) in a Petri dish with potato dextrose agar for 15 minutes at two different times (morning and afternoon) and heights (1 and 1.5 meters). The...

Analyse quantitative et qualitative des captures de tourteaux Cancer pagurus par la flottille de Manche-ouest ArchiMer
Latrouite, Daniel; Morizur, Yvon.
French potters from « Manche ouest » harbours ish edible crab Cancer pagurus in English Channel, Iroise Sea and along north Biscay Bay shelf. Monthly landings of the offshore fleet analysed from logbooks for the period 1985-1987 indicate changes in fishing areas. The mean length of males, the mean length of females and the sex-ratio have been analysed by Principal Component Analysis in 1981-1987 samples. The heterogeneity between catches from different statistical rectangle (30 x 40 nautical miles) was great enough to deduce a way of raising composition from samples to total landings. It also offers the possibility to verifiy and correct declaration on geographical origin of landings.

APPLICATION OF TICK SAMPLING ON ACARICIDAL BATH FREQUENCY IN Rhipicephalus (Boophilus) microplus (ACARI: IXODIDAE) Rev Salud Anim.
de la Vega,R; Díaz,G; Camejo,A; García,I.
In this paper, a tick sampling method developed by authors was employed with the purpose of saving acaricides and decreasing environmental pollution by the use of acaricidal dip control bathing bovines in relation to a critical number of estimated ticks. Twenty-six Jersey cows in production were sampled. The selected sampling regions were: rear leg, udder, perinea and tail. Samplings were done from 7 to 8 am, and female tick standard size pattern was 6 mm or longer. Every two weeks approximately, samplings and acaricidal baths were done (13 samplings in total). Only cows with 10 or more ticks received acaricidal baths. Results showed that the procedure allows saving 50% of acaricides.

Bat richness (Mammalia: Chiroptera) in an area of montane Atlantic Forest in the Serra da Mantiqueira, state of Minas Gerais, southeast Brazil Biota Neotropica
Xavier,Bruna da Silva; Carvalho,William Douglas; Dias,Daniela; Tabosa,Lorena de Oliveira; Santos,Carlos Eduardo Lopes; Esbérard,Carlos Eduardo Lustosa.
Abstract: In recent years there has been an increase in research interest in remnants of Atlantic Forest above 500 m a.s.l., such as in the Serra da Mantiqueira, which is considered a priority area for conservation. The chiropterofauna of the Serra da Mantiqueira remains relatively under-studied, and here we present a list of bat species from the "Reserva Particular do Patrimônio Natural (RPPN) Cachoeira do Tombo", a private conservation unit located in an area of montane Atlantic Forest in the Serra da Mantiqueira. Bats were captured with mist nets along trails and near a diurnal roost. A total of 498 individuals of 19 bat species belonging to the families Phyllostomidae, Vespertilionidae and Molossidae were captured. Phyllostomidae were captured only...

Bayesian sequential procedure to estimate the viability of seeds Coffea arabica L. in tetrazolium test Scientia Agricola
Brighenti,Carla Regina Guimarães; Cirillo,Marcelo Ângelo; Costa,André Luís Alves; Rosa,Sttela Dellyzete Veiga Franco da; Guimarães,Renato Mendes.
ABSTRACT: Tetrazolium tests use conventional sampling techniques in which a sample has a fixed size. These tests may be improved by sequential sampling, which does not work with fixed-size samples. When data obtained from an experiment are analyzed sequentially the analysis can be terminated when a particular decision has been made, and thus, there is no need to pre-establish the number of seeds to assess. Bayesian statistics can also help, if we have sufficient knowledge about coffee production in the area to construct a prior distribution. Therefore, we used the Bayesian sequential approach to estimate the percentage of viable coffee seeds submitted to tetrazolium testing, and we incorporated priors with information from other analyses of crops from...
