Etude de la production de juvéniles de saumon atlantique (Salmo salar). II - Influence de la densité sur l'alevinage. Campagne 1980-1981 Pisciculture du Quinquis
Provedor de dados: 5
Autores: Gaignon, Jean-louis; Prouzet, Patrick.
Les résultats de la campagne 1979-1980 ont montré la nécessité d'améliorer les performances de l'alevinage pour obtenir des résultats de production intéressants en cycle ouvert dans les conditions bretonnes. En effet, une augmentation du taux de smoltification à un an ne semble pouvoir être obtenue dans des conditions économiquement intéressantes (Charge très supérieure à 2 kg/m2), qu'à condition que la taille des tacons soit au moins égale à 6-7 cm en septembre de la première année. En conséquence, l'objectif expérimental de la saison 1980-1981 est de déterminer les conditions d'élevage qui puissent permettre d'obtenir un population homogène ayant une bonne croissance c'est-à-dire très supérieure à celle obtenue en 79-80....

The 'new' European fish culture systems: Recirculating systems, offshore cages, integrated systems
Provedor de dados: 5
Autores: Blancheton, Jean-paul; Bosc, Pierre; Hussenot, Jerome; Roque D'Orbcastel, Emmanuelle; Romain, David.
Over the last few decades, European fish culture was developed mainly as a intensive monospecific activity. In most countries, marine aquaculture cannot continue to develop on the shore line where it first settled due to high competition with other activities. It has now to move either offshore or into recirculation systems located in less occupied spaces. Fresh water availability and impact of fish production farms on the environment are strongly restraining the development of the activity, which is even declining in some countries such as France. Recirculation systems make it possible to decrease water consumption and facilitate waste treatment. Their economical feasibility is being demonstrated and they offer an alternative to developing fish farms....

Induced spawning of red drum, Sciaenops ocellatus: use of multivariate and univariate analysis methods in the search for side effects of LH-RHa treatments and ovarian development state upon spawn quality
Provedor de dados: 5
Autores: Gardes, Lionel; Villanove, Philippe; Buchet, Vincent; Fauvel, Christian.
The present work examines the usefulness of the combination of multivariate analyses and further one-way analysis of variance in the search for links between causes and effects in heterologous stimulation of spawning in fish. Stimulations with both 20 and 50 mu g . kg(-1) doses of [D Trp(6)] luteinizing hormone-releasing hormone analogue (LH-RHa) were effective in inducing and synchronizing spawning of red drum, Sciaenops ocellatus. Oocyte development monitoring using ovarian biopsy allowed treatment injections at different stages of maturation. The influence at stimulation time of female oocyte development state upon further development was shown. An interesting potential of second stimulation, leading to high quality spawns, was established and factors...

La pisciculture marine : un secteur industriel en émergence
Provedor de dados: 5
Autores: Paquotte, Philippe; Harache, Yves.
In a general context of low progression, European aquaculture has been characterized by the development of intensive fish farming. The most notable fact is the recent increase in intensive salmonid farming, with a turnover of almost two million ECU. More recently, the intensive farming of sea bass and sea bream has increased very rapidly in the Mediterranean Basin, although on a more reduced extent. Although research has started as soon as the seventies with a strong public incentive both for salmon, sea bass and sea bream, the development of these different types of aquaculture has not been done at the same pace. Some elements of sectorial dynamics are analysed such as research planning and financing, organization of the production and public policy. For...

Autores: Gaignon, Jean-louis; Prouzet, Patrick.
Le saumon atlantique, S. salar, est une espèce de salmonidés relativement délicate à élever dans sa phase eau douce, et seuls les pisciculteurs ou organismes directement intéressés par l'aquaculture ou le repeuplement tentent depuis quelques années des essais d'élevage, tous très décevant en Bretagne jusqu'à présent. Lors des la saison 1979-1980, 5 élevages au total ont été, à notre connaissance, pratiqués en Bretagne. Parmi ces élevages, 3 ont été suivis durant toute la saison (production de smolts 1+ uniquement.

Optimisation de deux systèmes de production piscicole : biotransformation des nutriments et gestion des rejets
Provedor de dados: 5
Autores: Roque D'Orbcastel, Emmanuelle.
Sustainability of fish aquaculture is currently subjected to environmental protection enhancement and to increasing restrictions of water and energy availability. The aim of this work was to study the biotransformations and waste management in a salmonid french farm (Charles Murgat S.A.S, Isère). Quantification of the wastes is necessary for the farmers and administrations to define control tools and treatment systems in view of water legislation respect (French water low, EC Water Framework Directive). The nutritional method gives a direct relation between feed and effluent fluxes. This method is easier to use than the hydrobiological method, which requires precise flow rate and concentration measurements (difficult and expensive). Solid waste treatment...

Autores: Méro, David.
Finfish farming diversification is a reality nowadays in France: this work brings the interest of the whole commodity chain for new fish species. This report identifies the species criterions of choice from inquiries beside professionals of the commodity chain, proposes a selection method and tackles, in example, the choice of new species for fish farming in cages on the west coasts of France, from Bay of Biscay to the North Sea. ' Method is divided in two stages: firstly an elimkation stage, which aims are to select from the 25 000 fish species, potential species by using redhibitory postulates, secondly a position stage which classifies the remaining species. A list of 53 species is proposed. Selection has been stopped because of the shortage of data....

Modélisation de la croissance des poissons en élevage
Provedor de dados: 5
Autores: Muller-feuga, Arnaud.
After a literature overview of growth models applied to intensively cultured fishes, a new one is proposed for assistance in rearing operations, with following characteristics. A simple and integratable mathematic expression simulates growth while eliminating individual weight influence. It gives way to a specific growth general definition. Temperature action mode on growth speed is simulated by substraction of two exponential functions. An automatic calculation method of thermal parameters is proposed. The torpid action of low temperatures is considered. Feeding ration influences growth through simple rules which are explicitly taken in account by mean of a two parameters function. The other growth factors, more difficult to seize, are expressed through a...

Pisciculture marine. Elements de prospective
Provedor de dados: 5
Autores: Gerard, Andre.
Introduction: To develop its 2005-2009 strategic plan, IFREMER made two prospective analysis studies in 2003: a thematic prospective analysis and a sectorial prospective analysis. The "aquafarming" sectorial prospective analysis, based primarily on an IFREMER idea, particularly brought to light the difference in nature of problems posed by the future evolution of shellfish farming, fish farming and other stockbreeding (pearl farming and shrimp farming). In addition, the prospective analyses made on an international scale by the FAO (2002, 2004) and the IFPRI (2003) emphasise that the development of aqua farming is the required condition for satisfying world demand of consumer aquatic products, given the foreseeable weak growth, indeed, the stagnation of...

Etude de la production de juvéniles de saumon atlantique (Salmo salar) - 1 - Résultats de la saison 1979-1980 Pisciculture du Quinquis
Provedor de dados: 5
Autores: Gaignon, Jean-louis; Prouzet, Patrick.
La pisciculture du Quinquis, sise près de Landivisiau (29), a pour objet la production intensive de smolts de saumon atlantique (Salmo salar) dans le cadre d'un programme d'aménagement et de repeuplement de la rivière Elorn. Depuis sa mise en eau (1976) les résultats ont été décevants et ceci à cause, d'une part de difficultés de démarrage (problèmes alimentaires en autres), d'autre part de problèmes sanitaires : la furonculose ayant entrainé des mortalités importantes dès le 1er automne (alevins à bonne croissance) ou en fin d'hiver. Au total, la survie a toujours été très faible et la production de smolts négligeable. C'est pourquoi, à partir de la saison 79-80, les objectifs ont été tournés davantage vers l'expérimentation tout en conservant un objectif...

The use of Arthrospira platensis in rearing Nile tilapia (Oreochromis niloticus) in salt water
Provedor de dados: 124
Autores: Leite,Lorena Alves; Quaresma,Fabrízia da Silva; Ribeiro,Pedro Florêncio; Farias,Wladimir Ronald Lobo; Souza,Bartolomeu Warlene Silva de.
ABSTRACT Nile tilapia (Oreochromis niloticus) is a euryhaline species which, in marine systems, can provide animal protein where fresh water is scarce. As a result, adequate water management to maintain sustainability is essential, and the use of a salt water recirculating system would be an advantage at the present time. In addition, Arthrospira platensis is used in the diet of aquatic organisms, as it is rich in protein. The aim of this study, therefore, was to evaluate the use of A. platensis as a food supplement in the performance of Nile tilapia in a salt water recirculating system. The experimental model included two groups, with four replications. Each crop had a duration of 45 days (control and test), giving a total of 90 days, with the control...

Provedor de dados: 124
Autores: Ribeiro,Pedro Florêncio; Leite,Lorena Alves; Quaresma,Fabrízia da Silva; Farias,Wladimir Ronald Lobo; Sampaio,Alexandre Holanda.
ABSTRACT The aim of this study was to evaluate different levels of dietary supplementation with dried Arthrospira platensis meal during the breeding season of the tambatinga hybrid, using zootechnical performance, haematological parameters and percent composition of the fillet, and by measuring the parameters of water quality. Experimental breeding lasted 64 days. The fry, with an initial weight of 3.56 ± 0.02 g, received diets with two levels of supplementation (20 and 40%) and one control (commercial feed, without the addition of A. platensis meal). The water quality parameters over safe limits were total ammonia (NH3), nitrite (NO2-), and nitrate (NO3-), which increased as the level of supplementation increased, but did not cause any mortalities. The...

Innovative molecular approach to the identification of Colossoma macropomum and its hybrids
Provedor de dados: 42
Autores: Gomes,Fátima; Schneider,Horacio; Barros,Claudene; Sampaio,Dioniso; Hashimoto,Diogo; Porto-Foresti,Fábio; Sampaio,Iracilda.
Tambaqui (Colossoma macropomum) is the fish species most commonly raised in the Brazilian fish farms. The species is highly adaptable to captive conditions, and is both fast-growing and relatively fecund. In recent years, artificial breeding has produced hybrids with Characiform species, known as "Tambacu" and "Tambatinga". Identifying hybrids is a difficult process, given their morphological similarities with the parent species. This study presents an innovative molecular approach to the identification of hybrids based primarily on Multiplex PCR of a nuclear gene (α-Tropomyosin), which was tested on 93 specimens obtained from fish farms in northern Brazil. The sequencing of a 505-bp fragment of the Control Region (CR) permitted the identification of the...
