L'aquaculture du Macrobrachium rosenbergii aux Antilles Francaises
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Lacroix, Denis.
The aquaculture of Macrobrachium rosenbergii is launched in Martinigue by the regional council in 1976. A first "green water" type hatchery is built and provides juveniles to the first ponds. In 1978, CNEXO is asked to cooperate in scientific assistance. A new hatchery is built with COP "clear water" system and produces in 1980. The development of ponds (20 ha) needs the increase of the hatcheries capacity, which is now done with one single method and intensive larval first stage (7-8 millions PL. cap). In Guadeloupe, the first ponds started in 1978. Two cooperatives and 11 ha of ponds at this time have determined the construction of CNEXO in the construction of a regional hatchery. A small light one is already under production since July 83.

Culture en conditions optimisées de la macroalgue rouge &lt;Gracilaria gracilis&gt; (stackhouse) steentofr et al. dans le lac de Bizerte
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Ksouri, J.; Challougui, I.; Mensi, F.
La culture de Gracilaria  a été réalisée selon le mode de bouturage dans la partie Nord-Est du lac de Bizerte du 15 Avril au 31 Mai 2006 afin de déterminer l'effet des conditions initiales optimisées sur le rendement final.  Ces conditions initiales,  sont caractérisées par une culture sur le fond (sur cordes tendues), un poids initial des touffes de 200 g, une distance entre les rangées de culture de 50 cm et un écartement entre les touffes de 30 cm; de ce fait, la densité initiale est de 1,4 kg/m². Au terme de 46 jours de culture, nous avons enregistré un accroissement du poids de 200 g à 1280 g engendrant un taux de croissance spécifique de 4,03 %/j et une densité finale de 9,1kg/m² (soit 91t poids frais/ha).

Evaluation de la capacité regénèratrice de l’algue rouge "Gracilaria verrucosa" (hudson) papenfuss  du lac de bizerte (tunisie septentrionale)
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Ksouri, J.; Mensi, F.; Salhi-Hamza, K.
Afin d’évaluer le potentiel de régénération de Gracilaria verrucosa du lac de Bizerte, une culture expérimentale, in situ sur cordes tendues sur le substrat, a été mise en place à partir de boutures de 200 g. Au terme de quatre mois de culture, de février à mai 2003, les cordes ont été soumises à une, deux, trois ou quatre coupes. L’analyse statistique montre que la meilleure situation est représentée par les touffes qui n’ont subi qu’une seule coupe à la fin du mois de mai; dans ce cas, ces touffes ont un poids final de 1771,4 g et un taux de croissance spécifique de 1,8.

l'Aquaculture (pisciculture et crevetticulture) dans la vallée du fleuve Sénégal: potentialité et perspective
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Diallo, A.; Diouf, P.S.; Ngom, M.; Ndiaye, V.
l'Aquacuulture dans sa composante pisciculture à fait l'objet de plusieurs expérimentations dans la vallée du fleuve Sénégal  par le biais  de projet de production  ce dernier n'a pas donné de résultats escomptés. L'Aménagement de la vallée  à induit des disponibilités en terre et eau qui offre à l'aquaculture les possibilités d'un developpement durable notamment la pisciculture et crevetticulture.

Cultivos de moluscos bivalvos
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Pascual, M.S.; Zampatti, E.A.
Bivalve culture in Argentina is beginning to develop commercially. Research was carried out at the North Patagonian gulfs (San Matias, San Jose and Nuevo)and focused three native species: the tehuelche scallop Aequipecten tehuelchus, the puelche oyster Ostrea puelchana and the common mussel Mytilus edulis platensis. Results achieved on each of these three species were different. In the case of scallops, the development of commercial aquaculture did not seem promising for many years due to the fact that production was sustained by natural populations: the dredge fishery of the San Matias Gulf and the diving fishery of the San Jose Gulf. Preliminary culture experiments dealt with larval fixation on artificial collectors and growth to commercial size on...

Amélioration de la production d'Artemia dans les salines tunisiennes par fertilisation minérale : détermination de la dose optimale d'emploi.
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Hussenot, J.; Aloui, N.; El Abed, A.
In order to test the fertilization effect on Artemia production, six treatments of a mineral fertilization with di-ammonium phosphate (DAP) and urea (0.25*F; 0.5*F; 0.75*F; 1*F; 1.5*F; 2*F with F = 15 mg/L of DAP and 15 mg/L of urea) were compared to a control unfertilized. After the initial fertilization (day 0), a half a dose was brought once a week. At day 8, Artemia nauplii were inoculated in all tanks  at the rate of 50 nauplii per liter. Physico-chemical and biological parameters of the culture were analysed each week, during the 48 days of experiment. The results showed that the optimal dose is 0.75*F; it gaves the maximal phytoplanctonic biomass expressed by chlorophyll-a has and it allowed to obtain a maximal production of Artemia (cysts and...

New developments in the high density flow-through culturing of brine shrimp &lt;i&gt;Artemia&lt;/i&gt;
Provedor de dados: Open Marine Archive
Autores: Lavens, P.; Baert, P.; De Meulemeester, A.; Van Ballaer, E.; Sorgeloos, P.
A closed culture system for the high density culturing of &lt;i&gt;Artemia spp.&lt;/i&gt; in 300-liter tanks using a new formula of artificial seawater and micronized waste products from agricultural crops as food is described. Culture conditions are greatly improved by applying a new filter technique and an electronic transparency meter which controls food distributions automatically. A total volume of 6,000 liters of culture water recirculated over a rotating biological contactor, a cross-flow sieve and a plate separator at a flow rate of 3000 liters per hour.Production yields obtained with this culture system, when extrapolated to a 1 m³ tank, indicate that 50 g of brine shrimp cysts can be converted into 20 kg of fresh (wet dry) pre-adult...

High-density production of the rotifer &lt;i&gt;Brachionus plicatilis&lt;/i&gt; in a recirculation system: consideration of water quality, zootechnical and nutritional aspects
Provedor de dados: Open Marine Archive
Autores: Suantika, G.; Dhert, Ph.; Nurhudah, M.; Sorgeloos, P.
Rotifers were reared on the artificial diet culture Selco® in batch and recirculation conditions at different water exchange rates. The different rearing conditions resulted in considerable changes in water quality, which in their turn affected rotifer growth and food consumption. At a daily water exchange rate of 100%, no positive effect was obtained in rotifer growth compared to the batch rearing system, but the rotifer culture period could be prolonged by 1 week. By increasing the daily water exchange rate from 100 to 300% the maximum rotifer density could be significantly (&lt;i&gt;P&lt;/i&gt; &lt; 0.05) increased from 1800 to 2500 individuals ml&lt;sup&gt;-1&lt;/sup&gt;. At the highest recirculation rate (daily water exchange of 500%) the highest...

Provedor de dados: Open Marine Archive

The live food enrichment technique using emulsions for nutritional deficiencies in rotifers and &lt;i&gt;Artemia&lt;/i&gt; was further investigated as a tool for transferring therapeutics through the food chain. &lt;i&gt;Artemia&lt;/i&gt; nauplii and the rotifer &lt;i&gt;Brachionus plicatilis&lt;/i&gt; were enriched with a self-emulsifying concentrate in which the therapeutic mixture trimetoprim: sulfamethoxazole was incorporated. An analytical method and protocol for the quantification of trimethoprim and sulfamethoxazole in a heterogeneous biological matrix, such as &lt;i&gt;Artemia&lt;/i&gt; , was developed using High Performance Liquid Chromatography. When applying a 24h enrichment period, the accumulation of both drugs in &lt;i&gt;Artemia&lt;/i&gt;...
