Última Amélioration de la production d'Artemia dans les salines tunisiennes par fertilisation minérale : comparaison entre deux types de fertilisants minéraux OceanDocs Hussenot, J.; Aloui, N.; El Abed, A.. Pour augmenter la production de masse en salines tunisiennes de l’espèce locale Artemia tunisiana, nous avons entrepris d’optimiser l’emploi de fertilisants minéraux azotés et phosphorés. La première phase, présentée ici, a permis de choisir entre deux stratégies proposées dans des travaux internationaux, utilisant soit le phosphate double d’ammoniaque (DAP) et l’urée, soit le nitrate de potassium et le triple superphosphate. L’expérience a été menée avec 3 répliquats par traitement durant 44 jours. L’effet de chaque fertilisation a été significatif (p<0,10) comparé aux essais témoins, sur le développement de la biomasse microalgale, ainsi que sur la production de cystes et d’adultes d’Artemia, qui a été augmentée d’un facteur 2. La première stratégie...

Ano: 2002 URL: http://hdl.handle.net/1834/249 Impact of the reproduction dynamics on genetic variation in the European flat oyster Ostrea edulis ArchiMer Lapegue, Sylvie; Taris, Nicolas; Lallias, Delphine; Bonhomme, Francois; Boudry, Pierre. The European flat oyster (Ostrea edulis L.) is a marine bivalve whose natural geographical distribution ranges along the European Atlantic coast from Norway to Morocco, in addition to the Mediterranean and Black Sea. The latest results obtained on the genetic differentiation between these populations have led us to pursue studies at a finer scale, in order to estimate the effective number of breeders and the temporal dynamics of reproduction and, more specially, recruitment. Several experiments were performed to document (1) the variance in allele frequencies during a natural settlement period; (2) the paternal contribution to fertilization by analyzing larvae sampled at the brooding stage within individual females; (3) the variance of individual...

Ano: 2004 URL: http://archimer.ifremer.fr/doc/2004/acte-3436.pdf Induce spawning and larval reading of gilthead sea bream (sparus aurata)collected from fish farms, egypt OceanDocs Aziz, F.K.; Zaki, M.I.; El-Absawy, M. El-G.. Sparus aurata females in captivity were injected with human chorionic gonadotropin hormone (HCG), pituitary extraction and both them during the spawning season. First hormonal treatment was applied as cumulative doses required for successful ovulation ranged from 4500 to 7500 IU\fish, the maximum fertilization percent was 71. The ovulation period under the influence of this treatment extended up to 14 days. In the second experiment, the total dose requirement for successful ovulation ranged from 2 to 4 pituitary extractions. Fish and the maximum fertilization percent recorded was 81, while the longest ovulation period obtained was 15 days. In the third experiment the total doses required for successful ovulation ranged from 2 pituitary extractions and 4500...
