Projet d'elevage du loup en mer : etude technico-economique du pregrossissement et du grossissement
Provedor de dados: 5
Autores: Tanguy, Renan; Le Grel, Laurent.
After 12 years of a difficult start, the sea bass (Dicentrarchus labrax) breeding projects are multiplying. Faced with the constraints presented by the sites used in the past, farming at sea seems to offer conditions more conducive to the growth and survival of the animals. The zootechnical data from the farm makes it possible to link the rate of growth and the thermal profile of the site. Risks and uncertainties still weigh heavily on aquafarming projects, but solutions such as insurance are helping to improve their economic feasibility. The economic and financial analysis comes up with good overall profitability of the project, even if the duration of the breeding cycle and the necessity to ensure a progressive increase in operating capacity make the...

Cryopreservation of sea bass (Dicentrarchus labrax) spermatozoa in experimental and production simulating conditions
Provedor de dados: 5
Autores: Fauvel, Christian; Suquet, Marc; Dreanno, Catherine; Zonno, Vincenzo; Menu, Bruno.
A sperm cryopreservation protocol adapted from turbot, was tested on sea bass using either 250-mu L straws or 1.5-mL cryovials. A dilution to 1/3 in Mounib's extender and a cooling rate of 65 degrees C.min(-1) allowed frozen sperm to recover an initial motility similar to that of fresh sperm at thawing; however, significant differences in motility (P &lt; 0.001, n = 10 fish semen) were observed at further post-activation times, the motility decrease being faster in thawed sperm. At the experimental scale, triplicate inseminations of 2-mL aliquots (approximately 2 000 eggs) showed a significant fertility decay of thawed sperm compared to that of fresh sperm (P &lt; 0.01, n = 12 fish semen) when a discriminating 35.10(3) spermatozoa to egg ratio was applied....

Tri d'alevins de loup et de dorade au stade juvénile (0,2 - 12 g)
Provedor de dados: 5
Autores: Lemarie, Gilles; Gasset, Eric.
The authors present the necessary to sort catfish and sea bream fries in order to limit cannibalism, to constitute homogeneous groups. In the same time they studied different sorters (bars sorter, grating sorter and the conception of an experimental sorter) and their effects on the juveniles (behaviour).  Introduction: In hatchery, early sorting of Sea Bass or Sea Bream fry after weaning can become necessary for several reasons: a) To obtain homogeneous batches thus simplifying growing management by better controlling: - Specific water flow for precise ranges of size or weight, - Food distribution granularity, - Daily feeding rate. b) To limit cannibalism which can become high when population dispersion is spread out. This dispersion greatly increases...
