A hierarchical Bayesian model for embedding larval drift and habitat models in integrated life cycles for exploited fish
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Rochette, Sebastien; Le Pape, Olivier; Vigneau, Joel; Rivot, Etienne.
This paper proposes a hierarchical Bayesian framework for modeling the life cycle of marine exploited fish with a spatial perspective. The application was developed for a nursery-dependent fish species, the common sole (Solea solea), on the Eastern Channel population (Western Europe). The approach combined processes of different natures and various sources of observations within an integrated framework for life-cycle modeling: (1) outputs of an individual-based model for larval drift and survival that provided yearly estimates of the dispersion and mortality of eggs and larvae, from spawning grounds to settlement in several coastal nurseries; (2) a habitat suitability model, based on juvenile trawl surveys coupled with a geographic information system, to...

ABSTRACT  Grapevine production by classical grafting methods and in commercial scale emerged over 130 years. This system remained handmade until the mid-1950s, when the first international certification programs aimed at obtaining mother plants with high viral sanity emerged. The necessity to increase the scale of production on industrial model and plant material production based on minimum morphological standards appeared at the end of the 1960s. Along the 1970s, research unlocked knowledge on semi-automated grafting, process hygiene, use of plant growth regulators and understanding of physiological events of rootstock-scion compatibility, callus formation and rooting. So, until the mid-2000s, certification schemes and propagation processes advanced...

Approche quantitative de la fonction de nourricerie jouée par les systèmes vasières-estuaires
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Parlier, Emmanuel.
Coastal fish populations settle more or less frequently, at various stages, estuarine systems. Tidal marshes are one of the components of these mosaics of habitats. The first part of this work describes fish assemblages through the utilisation of these systems by fishes analysed in order to propose a revised functional classification of ecological guilds. T h i s new classification is used to compare fish communities of four estuarine systems in the western coast of France: the Mont Saint- Michel Bay, the Saint-Brieuc Bay, the Loire estuary and the Aiguillon Bay. The second part aims at characterizing the nursery function as defined by Beck et al. (2001). Acombinative approach based on gut content analysis, and stable isotope analysis shows that Yo Y s e a...

Closed soilless growing system for producing strawberry bare root transplants and runner tips
Provedor de dados: Pesquisa Agropecuária Brasileira
Autores: Giménez,Gustavo; Andriolo,Jerônimo Luiz; Janisch,Djeimi; Godoi,Rodrigo.
The objective of this work was to test a closed soilless growing system for producing bare root transplants and runner tips of two strawberry clones, using two categories of substrates. The system used corrugated roofing panels of fiber-cement, over which a substrate layer was used as a growing bed. The nutrient solution was pumped from a reservoir toward the upper end of the roofing panels and drained back to a reservoir. Plant growth and development were determined for two advanced strawberry clones, grown in sand or in Plantmax organic substrate. Growth of the stock plants and the number and dry mass of bare root transplants were similar in the substrates, but bare roots differed in their crown diameters by substrate. For number of runner tips, no...

Cocoa propagation, technologies for production of seedlings
Provedor de dados: Revista Brasileira de Fruticultura
Autores: Sodré,George Andrade; Gomes,Augusto Roberto Sena.
Abstract  The vegetative propagation in cacao has been used in Central America since the beginning of the last century. However, only from the end of the century this technique has been intensified in the state of Bahia, where vegetative propagation changes have increased the yield of cocoa growing areas, especially those using other technologies associated with clonal seedlings. The use of clonal garden to collect stems in nursery can reduce by 80% the space required for maintenance of stock plants. On the other hand, the buds obtained from orthotropic and plagiotropic shoots are used to improve the performance protocols and reduce production costs of seedlings. Among the current and future challenges in the production of cocoa seedlings emphasizes the...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Gardner,   Justin G.; Eastwood,   David B.; Brooker,   John R.; Klingeman,   William E.
This article summarizes a study of consumers' willingness to pay (WTP), in urban areas in Tennessee, Mississippi, and Michigan, for a powdery mildew resistant dogwood tree. Powdery mildew is a disease affecting flowering dogwoods that can limit growth, detract from the appearance, and may cause plant decline and death.  Study objectives were to provide information about consumers' WTP and to identify potential marketing strategies for the introduction of the disease-resistant tree. On average, survey respondents indicated they are willing to pay a $13.35 premium for a flowering dogwood tree which is resistant to powdery mildew. Regression results led to inferences that the presence of dogwoods in a respondent's yard, presence of dogwoods infected with...

Croissance de jeunes palourdes (Venerupis semidecussata) en nurserie et en mer en fonction des conditions d'élevage
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Lucas, Albert.
The japanese palourde Venerupis semidecussata was reared in the Bay of Brest, using hatchery reared spat. Experiments were performed with individuals of lenght 2 to 10 mm raised in a nursery, using raceways with slow running water enriched with unicellular algae, And also with individuals of lenght 8 to 20 mm raised at sea in suspended culture. It was observed that growth depends upon four groups of factors : (1) the functioning and equipment of the raceways, (2) the quantity and quality of the food, (3) the temperature and (4) various physico-chemical factors. When the equipment is satisfactory and when the physico-chemical fac­tors are normal for the species in question, the rate of growth depends essen­tially on the quantity of food, provided that the...

Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Cheminee, A.; Merigot, B.; Vanderklift, M. A.; Francour, P.
Human activities facilitate coastal habitat transformation and homogenization. The spread of marine invasive species is one example. This in turn may inluence ish recruitment and the subsequent replenishment of adult assemblages. We tested habitat complexity effect on ish (Teleostei) recruitment by experimentally manipulating meadows of the habitat-forming invasive macroalga Caulerpa taxifolia (Chlorophyta). Among the fourteen ish species recorded during the experiment, only two labrids (Coris julis and Symphodus ocellatus) settled in abundance among these meadows. Patterns in the abundance of these juveniles suggested that reduced tri-dimensional meadow complexity may reduce habitat quality and result in altered habitat choices and / or differential...

Effect of nursery habitat degradation on flatfish population: Application to Solea solea in the Eastern Channel (Western Europe)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Rochette, S.; Rivot, Etienne; Morin, Jocelyne; Mackinson, S.; Riou, Philippe; Le Pape, Olivier.
Estuaries and coastal waters are essential nursery habitats for many marine species, and especially for flatfishes. Thus, investigating how anthropogenic disturbances affect the quality of these habitats is of major importance to understand their consequences on the population renewal of marine species. The aim of the present study was to analyse the effects of estuarine habitat degradation on the population of the common sole in the Eastern Channel, a key species in the fish community and fisheries in this area. We especially focused on the drastic drop in the surface area and on the low water quality of the Seine estuary, the main river of the Eastern Channel. A geographic Information System (GIS) was used to develop quantitative maps of sole nursery...

Provedor de dados: Tropical Plant Pathology: fitopatologia brasileira
Autores: Dhingra,Onkar D.; Costa,Maria L. N.; Silva, Jr.,Geraldo J.; Mizubuti,Eduardo S. G.
The essential oil extracted from mustard (Brassica rapa) seeds was evaluated for its effect on suppression of Rhizoctonia solani growth in vitro, and in field soils, for reducing saprophytic substrate colonization and seedling damping off and blight using snap beans as indicator plant, the in vitro growth was completely inhibited at a concentration of 50 mul/l. The saprophytic substrate colonization in soils 24 h after treatment was drastically reduced to 45% at 150 mul/kg soil concentration, in contrast to 100% colonization at concentrations of 0, 50, or 75 mul/kg. This recovery rate gradually declined to 6% and 60%, respectively, in nine days. A control of pre and post-emergence seedling damping off and blight in common beans (Phaseolus vulgaris),...

Different types of pregrowth of the Japanese palourde are compared on the some site. The method by upwelling which is the more common used, to have good growth, requires a compromise between the running and the raised biomass.  Two periods are critical, in the summer the growth of mollusks is stopped because of a decrease in the phytoplanktonic production ;  in the winter, a fall in temperature lessens filtration and stops growth. The results concern clams consummatation rates of particular food (chlorophyll, protids, lipids, glucids) as weIl as the way to supply the decreasing growth : increase of phytoplankyonic production in the summer by recycling waters from nurseries that are loaded with ammoniac and raise winter temperatures by using under-ground...

Food limitation of juvenile marine fish in a coastal and estuarine nursery
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Saulnier, E.; Le Bris, H.; Tableau, Adrien; Dauvin, J.c.; Brind'Amour, Anik.
Despite their importance for species conservation and sound management of exploited living resources, the density-dependent mechanisms that regulate wild populations are among the least understood process in ecology. In many marine fish species, there is strong evidence that regulation occurs at the juvenile stage, when individuals concentrate in spatially restricted nurseries. However, little is known about the underlying mechanisms. Whether competition for food resources determines fish growth and survival is particularly controversial. We investigated whether food supply may have limited juvenile fish production (integrating both growth and survival) in a coastal and estuarine nursery in western Europe. Using a recent bioenergetics-based approach, we...

Growth and survival of pink shrimp (Farfantepenaeus paulensis) postlarve in cages and pen enclosures
Provedor de dados: Scientia Agricola
Autores: Vaz,Luciano Jensen; Wasielesky Jr.,Wilson; Cavalli,Ronaldo Olivera; Peixoto,Silvio; Santos,Marcos Henrique Silva; Ballester,Eduardo.
Technology for the culture of the pink shrimp Farfantepenaeus paulensis in low-cost cages and pen enclosures was developed together with artisanal fishermen of the Patos Lagoon estuary, southern Brazil. Although the production of postlarvae (PL) under laboratory conditions is well documented, survival and growth during the nursery phase cages and pen enclosures in the nature has not yet been analyzed. Therefore, the present study compared survival and growth of F. paulensis postlarvae reared either in cages or pens. Six cages (2.0 ´ 2.0 ´ 1.4 m) of PVC-coated polyester with a mesh size of 1.5 mm were stocked with 800 PL26 each. To assess the effect of the substrate, a 10 cm layer of sand was added to three of these cages to simulate a pen enclosure. No...

Dieback of mamey sapote (Pouteria sapota) grafts is the most important disease during vegetative propagation in commercial nurseries. In 2008, Lasiodiplodia theobromae identified by cultural, morphological and molecular characterization was associated with this disease in 97 % of necrotic rootstocks and scions samples from a nursery in Guerrero, México. The fungus was inoculated onto the binding site of El Mexicano grafted plants. Dieback symptoms and gradual drying with cracking of the bark from the apex to the base of the scion were observed 30 d after inoculation. Abundant mycelia and pycnidia were found on inoculated scions and graft union areas, in the periderm, and on leaf scars. Transverse sections of inoculated scions tissues showed pycnidia....

Provedor de dados: Chilean Journal of Agricultural Research
Autores: Sarwar,Naeem; Maqsood,Muhammad; Aftab Wajid,Syed; Anwar-ul-Haq,Muhammad.
Producing vigorous seedlings and transplanting them at the appropriate age are the most important factors for obtaining high yield in rice (Oryza sativa L.) paddy production. The impact of seeding densities, N, and seedling age was evaluated in this experiment after transplanting 10, 20, 30 and 40-d old seedlings raised by using different seeding rates (high and low) and N conditions (with and without) in the 2008 and 2009 rice growing seasons. The study revealed that 10-d-old nursery seedlings, irrespective of seeding densities and fertilizer application, showed higher yields and yield attributes (productive tillers, plant height, 1000-grain weight, and straw yield), while at later stages significant interaction was observed with nursery management....

Autores: Paumier, A.; Tatlian, T.; Reveillac, E.; Le Luherne, Emilie; Ballu, S.; Lepage, M.; Le Pape, Olivier.
All around the world, an increasing proportion of estuarine systems are facing massive proliferations of green macroalgae, called green tides, in response to nutrient enrichment. The consequences of this perturbation for ichthyofauna that use estuarine systems as essential fish habitats remain understudied. To estimate these consequences, we combined outputs of both macroalgae proliferation and fish community surveys conducted for the European Water Framework Directive in thirteen estuaries in northwestern France, a region where green tides are of great concern. The approach revealed the influence of green tides on estuarine fish communities. The response of each community to the green tides differed according to their functional guild composition. Benthic...

Provedor de dados: Acta Botanica Brasilica
Autores: Goetten,Luis Claudio; Moretto,Geraldo; Stürmer,Sidney Luiz.
Mycorrhizal fungus inoculum produced on-farm can be used during production of woody plant seedlings to reduce costs associated with purchase of commercial inoculant and fertilization. This study aimed to test the efficiency of a mycorrhizal inoculant produced on-farm to promote growth and nutrition of woody species in combination with different levels of phosphorus. Plants were submitted to different treatments of phosphorus (0, 40 and 80 mg P/dm3) and mycorrhizal inoculation (uninoculated, and inoculation with Rhizophagus clarus [Rc] or Claroideoglomus etunicatum [Ce]). Species included were Luehea divaricata, Centrolobium robustum, Schinus terebinthifolius, Garcinia gardneriana, Cedrella fissilis, and Lafoensia pacari. The inoculum was produced using the...

Intensive rearing of juvenile oysters Crassostrea gigas in an upwelling system : optimization of biological production
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Bacher, Cedric; Baud, Jean-pierre.
Seasonal growth of juvenile oysters (Crassostrea gigas) kept in an intensive upwelling system was studied from 1984 to 1986 in 60 to 90-day growth experiments. Saline ground water was used to produce Skeletonema costatum which was injected as food into the water supplying the upwelling system. Oyster density, water flow, phytoplankton concentration, temperature and frequency of food addition were controlled. Oyster growth was analysed with multidimensional contingency tables and correspondence analysis. The factors, in order of decreasing influence on growth, were temperature, food concentration and oyster density. A rearing strategy was deduced from the growth analysis for summer and winter. In summer, the density of  120,000 oysters/m2, the flow rate of...

Autores: Ventura,Robson; Silva,Ubiratã A. T. da; Ostrensky,Antonio; Cottens,Kelly.
Current efforts for restocking natural populations of the mangrove crab Ucides cordatus (Linnaeus, 1763) in Brazil have focused on developing a methodology for stimulating the metamorphosis of U. cordatus larvae at a large scale. The aim of the present study was to compare the mortality rates both in individual and mass conditions, during the induction of metamorphosis of megalopa to juvenile in U. cordatus, without the use of mangrove sediment as substrate. Furthermore, the importance of intraspecific antagonistic behavior on survivorship rates during early post-metamorphosis period was investigated. Metamorphosis was induced by the use of water conditioned with conspecific adults (30 indiv. 100 L-1 for 24 hours). In the first assay, megalopae were...

Is artificial habitat diversity a key to restoring nurseries for juvenile coastal fish? Ex situ experiments on habitat selection and survival of juvenile seabreams

Man‐made infrastructures have become ubiquitous components of coastal landscapes, leading to habitat modification that affects the abundance and diversity of marine organisms. Marine coastal fish have a complex life cycle requiring different essential habitats. One of these habitats is known as a nursery, a place where juveniles can settle in large numbers, survive, and grow to contribute to the adult population. Nurseries are mainly found in shallow, sheltered zones and are thus particularly impacted by urbanization, notably by harbors. The vertical featureless structure of docks is very unlikely to be used by juveniles, which need complex habitats to find food and shelter from predators. Recent attempts to rehabilitate the nursery function in such...

Provedor de dados: Neotropical Ichthyology
Autores: Santander-Neto,Jones; Yokota,Leandro; Meneses,Thiago Silveira de.
Abstract The determination of the period of parturition and identification of nursery areas are fundamental for the management and conservation of a fishing resource. Through combination of monthly abundance, length measurements, and development time of embryos we inferred about parturition time of the Blacktip sharks, Carcharhinus limbatus, from Southwestern Atlantic. Specimens of C. limbatus were caught from 2002 and 2008 by artisanal fleets from three different locations along the Brazilian coast using gillnets (mesh width ranging between 30 and 120 mm between opposite knots and operating from 9 to 120 m in depth), handlines (19 to 140 m depth) and longlines (6 to 90 m depth). Through a comparative analysis of fisheries landing data collected, we have...

Autores: Waechter, Magali.
Summer mortality has been observed on oyster spat Crassostrea gigas since 1991 on french coasts. In our study, we deseribed symptoms observed during the mortality, especially adductor muscle weakness and we isolated strains on Zobell medium and TCBS from moribund spat. Strains isolated during a high mortality (60 %) were selected by experimental pathology on spat. Inoculation by bath led us to select a pathogenic strain (TNEMF6) for oyster spat. Phenotypic identification, phylogenetic study on 16S rDNA and quantitative DNA/DNA hybridisation showed that this strain belongs to Vibrio splendidus biovar II. Phenotyping and ribotyping with strains isolated during the study showed that only TNNIII7 and TNMB5 are similar to the pathogenic strain TNEMF6....

Substitutes for live microalgae in mariculture: a review
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Robert, Rene; Trintignac, P.
In mollusc hatcheries and nurseries, live microalgae are traditionally used as feed for bivalves. Despite recent improvements in efficiency, such intensive culture of microalgae represents major cost factors in the production of bivalve larvae and spat. In an attempt to provide cost-effective alternatives and to simplify hatchery-nursery procedures, non-living algal food has been developed over the past few years. Substitution products such as bacteria, yeast, vitamin or docosahexaenoic acid enriched powders, dry and concentrated microalgae and microcapsules have been tested and evaluated on an experimental scale. The present article reviews major research aimed at developing non living diets in mariculture, which generally resulted in lower growth and...

Little attention has been paid to flatfish parasitism as a potential factor of variation in year-class strength. The aim of this study was to evaluate the relationship between parasitic infection and nutritional condition of young-of-year (YOY) common sole. Sole were collected monthly from May (early settlement) to November 2004 in a mussel pole culture area, using a push-net or a trawl, and dissected for parasite identification and counts. Total lipids were extracted from the whole body and lipid classes quantified. Triacylglycerols to sterols (free form) ratio (TAG/ST) was used as an index of nutritional status. Digenean metacercariae infection, characterized by two dominant genera, displayed clear seasonal dynamics and the highest records yet reported...

ABSTRACT Six wide-ranging mangrove species, Rhizophora apiculata, R. mucronata, Avicennia marina, A. officinalis, Bruguiera gymnorrhiza, and B. sexangula, were selected to study the growth and survival of seedlings under three contrasting salinity treatments over a 30-week period: low (3-5psu), moderate (15-17psu) and high (33-36psu). Seedlings grown under high salinity exhibited significantly lower performance (p&lt;0.05) in survival rates, cumulative shoot height, mean growth rates, mean total leaf area, and mean dry weight, compared to those under low and moderate salinity regimes. The low salinity treatment provided the best conditions for initial establishment and growth of the seedlings of all species until 15-20 weeks of age. However, the same...

ABSTRACT Although dry bulb temperature (T) is the environmental variable most commonly used to classify thermal comfort in pigs, environmental assessment ratios provide more accurate information. The objective of this study was to correlate the sound pressure levels (SPL) produced by piglet vocalization with the thermal environment observed during the nursery phase, and subsequently establish thermoneutrality ranges. The experiment was conducted on a pig farm where T, relative humidity (RH), and SPL data were recorded between 9 am-5 pm for 42 days. The association between SPL and T in nursery phase piglets was verified; for thermal comfort to be possible, SPLs were 56.3 to 60.3 dB. The SPLs were subsequently used in predictor equations of ratios, and...
