A brief review of nutritional studies for Penaeus monodon ArchiMer
Liao, I; Liu, F.
In order to develop effective formulated for Penaeus monodon , sufficient information is needed on its nutritional requirements. Unfortunately, research on this area has been very limited. This paper outlines the results of such research. Since data on the nutritional requirements of P. japonicus are relatively well established, some of these data are also reviewed in this paper and are used as a basis for assessing the nutritional requirements of P. monodon . Protein, lipid, carbohydrate, mineral and vitamin requirements are evaluated from the parameters of growth survival and feed efficiency. Studies on the effects of enzymes and the development of microparticulate diet for larvae are also summarized.

Analyse des résultats d'une ferme d'élevage de crevettes sur 20 années : SODACAL 1984-2004. "Elasticité" de la capacité de production d'un écosystème bassin crevetticole ArchiMer
Della Patrona, Luc.
SODACAL prawn farm which was set up as a pilot farm for the development of a prawn industry in New Caledonia, saw its production exponentially rise from 1984 to 1992 (to 400 t/year, then experienced a sharp drop in 1993 (250 t/year) which carried on until 1997, and finally rose back to a stabilizing level around 400 t/year until 1999. The study analyses the difficulties observed before and during the drop of production. Among them, mortality outbreaks, other biological perturbations (benthic mat clearing and crab and fish mortality) and focus on the noxious state of the bottom (reduced and smelling sulfide hydrogen). It particularly shows that Syndrome 93 outbreaks could be observed on this farm from 1990. The analysis highlights the particular climatic...

Cycle sexuel et fécondité du mâchoiron Chrysichthys nigrodigitatus en lagune Ebrié, Côte d'Ivoire. OceanDocs
Otémé, Ziriga Josué.
L'évolution saisonnière du développement des gonades chez les femelles de Chrysichthys nigrodigitatus en lagune Ebrié (Côte d'Ivoire) a été étudiée sur un cycle annuel de reproduction. Sept stades macroscopiques de maturation des gonades ont été identifiés. Ces poissons ne pondent qu'une seule fois durant une saison de reproduction qui s'étend de juillet à novembre. La fécondité potentielle varie entre 4878 et 87724 ovocytes et 5438 et 36257 ovocytes respectivement pour le milieu naturel et le milieu d'élevage. La corrélation entre la fécondité et la longueur du poisson est légèrement plus marquée que celle entre la fécondité et et le poids des gonades

Ecologie bacterienne dans les bacs d'elevage larvaire de coquilles Saint-Jacques (Pecten maximus ) ArchiMer
Jacq, E; Moal, Jeanne; Samain, Jean-francois; Corre, S; Daniel, J; Nicolas, Jean-louis; Cochard, Jean-claude; Fera, P.
Larval rearings were performed with seawater either freshly pumped or after storage in a pond. Concerning bacterial populations these waters were characterized by a high diversity, little sized bacteria whose few of them (1%) were cultivable on Zobell medium. In the tanks, the bacterial ecosystem was modified by the presence of antibiotics, larvae and algae: the diversity was lowered, the cellular volume was increased by a factor 2 to 5, 100% bacteria were cultivable and chloramphenicol resistant, and their metabolism changed. Taxonomic screening showed no differences among the two waters neither at the beginning nor at the end of the rearings. However, depending on the water (stored or not) differences were identified for bacterial physiology and...

Evaluación de niveles de proteína y densidades de siembra en el crecimiento del camarón blanco Litopenaeus schmitti OceanDocs
Fraga, I.; Galindo, J.; de Arazoza, M.; Sanchez, A.; Jaime Ceballos, B.; Alvarez, S..
Para evaluar el efecto de diferentes niveles de proteína y densidades de siembra sobre el crecimiento de juveniles de camarón Litopaneus schmitti, se desarrolló un diseño experimental totalmente aleatorizado en estanque de tierra durante 72 días, con 16 tratamientos y 3 repeticiones, combinando tres niveles de proteína alimentar para definir la contribución del alimento natural al crecimiento de los camarones. La contribución del alimento natural al crecimiento fue entre 58.2 - 87.9% y los copépodos constituyeron el 65% del total de organismos del zoobentos. Una alta correlación negativa se encontró entre la cantidad de organismos epibentónicos y las densidades de siembra ensayadas.

Grow-out of sandfish Holothuria scabra in ponds shows that co-culture with shrimp Litopenaeus stylirostris is not viable ArchiMer
Bell, J; Agudo, N; Purcell, S; Blazer, P; Simutoga, M; Pham, Dominique; Della Patrona, Luc.
We examined the potential for producing the large numbers of sandfish (Holothuria scabra) needed for restocking programmes by co-culturing juveniles with the shrimp Litopenaeus stylirostris in earthen ponds. Our experiments in hapas within shrimp ponds were designed to detect any deleterious effects of sandfish on shrimp, and vice versa. These experiments showed that a high stocking density of juvenile sandfish had no significant effects on growth and survival of shrimp. However, survival and growth of sandfish reared with shrimp for 3 weeks were significantly lower than for sandfish reared alone. Increased stocking density of shrimp also had a significant negative effect on survival and/or growth of sandfish. A grow-out trial of juvenile sandfish in...

Increasing cyst yields in <i>Artemia</i> culture ponds in Vietnam: the multicycle system OMA
Baert, P.; Anh, N.T.N.; Quynh, V.D.; Hoa, N.V.; Sorgeloos, P..
In this study, one-cycle and multi-cycle culture systems for <i>Artemia</i> in seasonal salt ponds are compared. In one-cycle systems, <i>Artemia</i> is inoculated only once per season, while in multi-cycle systems ponds are drained and re-stocked several times per season. In Vietnam, three-cycle systems gave significantly higher cyst yields than did the one-cycle system. However, after two cycles, systems were not significantly different. Food limitation probably caused the steady decline in cyst yields, as observed in the one-cycle ponds. In these ponds, females have smaller broods (from the second cycle onwards) and during the last cycle the number of adult females is lower than in multi-cycle ponds.

Influence de la densite et de l'age des huitres japonaises (Crassostrea gigas ) sur la croissance et la composition biochimique en bassins de terre ArchiMer
Bodoy, A; Geiaron, P; Garnier, Jacqueline; Heurtebise, S.
Two different biomasses (100 g multiplied by m super(-2) and 1 kg multiplied by m super(-2)) of oysters were put in identical sea-water ponds, thus leading to different trophic conditions, corresponding to rearing techniques. Changes in growth, biochemical composition and sexual maturation were recorded for two age groups. The first one included 9 month-old oysters and the second one 21 month-old oysters, at the beginning of the experiment. For both age groups, significant differences were observed in growth and biochemical composition. Lipids were accumulated faster for the lower biomass. However, the only difference concerning glycogen was observed on the older oysters. They showed a peak at the lowest biomass and a decrease at the larger biomass. Sexual...

Microalgal production in oyster ponds: Nutrition and dissolved organic nitrogen ArchiMer
Maestrini, S; Robert, J.
Microalgal population of oyster ponds is dominated by several tychobenthic diatoms which provide a very good food to grow oysters. The mechanisms which allow them to dominate have been put under research. H.P.L.C. analysis demonstrated 17 amino acids amounted 10-17% of total DON, i.e. 0.6-11.5 mu g-at/l nitrogen. Serin and glycin were the most abundant. None of the substances was related to the presence of oyster. Glutamic acid, alanin and ornithin concentrations showed the greatest variations; they are suspected to play the major role as nutrient source. Screening of nutritional capabilities of ten local isolates of micro-algae to use 42 organic substances as sole source of nitrogen, demonstrated urea, glutamic acid and hypoxanthin are assimilated by all...

Prise simultanee de quatre sources d'azote par le microphytobenthos du chenal de Lauzieres (Charente Maritime-France) en ete ArchiMer
Collos, Y.
Simultaneous uptake of nitrate, nitrite, ammonium and urea by microphytobenthos incubated in batch mode immediately after sampling do not show any kind of interactions. A linear relationship is found between nitrate uptake and ammonium uptake, the latter values being about 2 to 3 times higher than former. Ammonium uptake was not saturated by a substrate level of 10 mu M, possibly indicating diffusion limited uptake. For all nitrogen sources, the uptake rate was related to the substrate concentration rather than the oxidation state of the nitrogen compounds.

X. Manejo de alimentación en estanques y alimentos amigables con el ambiente OceanDocs
Se realizaron bioensayos en agua estática para comparar los efectos de 1) la proteína dietaria y 2) el fósforo dietario sobre la acumulación de los nutrientes no asimilados en el agua de cultivo de poslarvas de Penaeus vannamei. Se evaluaron alimentos con 4 niveles de proteína dietaria (10, 18, 25 y 33%) y alimentos con 3 niveles de fósforo (0.4, 0.8 y 1.2%) con fosfato de sodio monobásico (NaH2PO4) como fuente inorgánica de fósforo. La acumulación de Nitrógeno inorgánico disuelto total (NIT) incrementó significativamente con el incremento en el nivel de proteína. El balance de masa de Nitrógeno constituyó el 87% de Nitrógeno que había entrado al medio de cultivo. La asimilación promedio de Nitrógeno en biomasa de camarón fue de 85, 71, 48 y 37% para los...
