Amélioration des techniques d'élevage de la chevrette Macrobrachium rosenbergii en Guyane ArchiMer
Griessinger, Jean-michel; Gondouin, Philippe; Dutto, Gilbert; Lacroix, Denis; Pollet, Thierry; Falguiere, Jean-claude; Mer, Gilles.
En 1987, l'analyse du système d'élevage en continu menée par l' IFREMER tant sur les fermes guyanaises que sur la station expérimentale de Kourou a permis de mettre en évidence les limites et les faiblesses de ce mode d'élevage. Elle a montré la nécessité d'un meilleur contrôle du cheptel depuis l'ensemencement jusqu'à la commercialisation afin de pouvoir atteindre de manière fiable des rendements de l'ordre de 2,5 T/ha/an.

Aménagement des techniques de production de la chevrette Macrobrachium rosenbergii en Guyane ArchiMer
Griessinger, Jean-michel; Lacroix, Denis; Falguiere, Jean-claude; Pollet, Thierry; Gondouin, Philippe; Mer, Gilles.
En 1987, la filière de production de chevrettes Macrobrachium rosenbergii en Guyane Française a fait l'objet d'intervention du laboratoire d'aquaculture de l'IFREMER à 2 niveaux : un appui technique à la profession, et des expérimentations à la station expérimentale gérée en commun par IFREMER et INRA, à KOUROU. L'appui technique a porté sur la formation d'éleveurs notamment pour le démarrage des exploitations, l'amélioration des techniques d'exploitation et de choix des classes détaillées commerciales, la maîtrise des caractéristiques du milieu d'élevage par l'utilisation des amendements classiques, la lutte contre la contamination des produits par les germes coliformes. Le programme de recherche a porté en 1987 sur l'analyse du milieu d'élevage et tenté...

Aquaculture et prospective : un passé simple et ses futurs antérieurs ArchiMer
Lacroix, Denis.
Aquaculture is one of the main supply of protein in feed for mankind, notably in Asia. It increases and had exceeded the level of production of world fisheries, which is decreasing. According to sites and rearing methods, aquaculture contributes to add value but also in some cases to impact negatively the aquatic ecosystems. In the coastal area, a rich and productive zone, but also a place of conflicts, this activity presents a high potential for development if it takes into account the rules of sustainability. The conditions of this sustainability may be cleared with appropriate methods of foresight analysis applied for each development project. The analysis of the professional experience of D. Lacroix for 33 years in aquaculture is structured in three...

HUFA levels in eggs of wild and cultured broodstock of <i>Macrobrachium rosenbergii</i> OMA
Lavens, P.; Piyatiratitivorakul, S.; Menasveta, P.; Sorgeloos, P..
The variation in egg quality, i.e. the potential of the egg to produce viable fry, is still a limiting factor in the commercial production of marine fish and crustacean fry. Better knowledge in this field would contribute to improved and especially more consistent hatchery outputs and to the development of more suitable broodstock diets. So far, objective criteria to evaluate egg quality are scarce. However, it is very likely that the nutrient composition of the eggs may be a good indicator for egg viability as it reflects the nutrient demands of the developing embryo and larva. Since (n-3) highly unsaturated fatty acids (HUFAs) have been identified as essential nutrients for the larvae of marine fish, shrimp and prawn a case study has been initiated with...

L'aquaculture du Macrobrachium rosenbergii aux Antilles Francaises ArchiMer
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.

Les cellules folliculaires secondaires de la crevette Macrobrachium rosenbergii (Decapoda, Palaemonidae): Mise en evidence d'un reseau tubulaire implique dans les echanges entre l'hemolymphe et l'ovocyte ArchiMer
Meuzy, J; Jugan, P; Zerbib, C.
The epithelial cells of the ovary secondary follicles have been studied in the prawn Macrobrachium rosenbergii using electron microscope and horseradish peroxidase. A network of circomvolutioned and anastomosed tubules, measuring about 0.15 mu m in diameter, communicates with the extracellular space. This tubular network is a temporary structure which extensively increases the permeability of the follicular epithelium.

Maturation performance, offspring quality and lipid composition of <i>Macrobrachium rosenbergii</i> females fed increasing levels of dietary phospholipids OMA
Cavalli, R.O.; Menschaert, G.; Lavens, P.; Sorgeloos, P..
The effects of increasing levels of dietary phospholipids (PL) on the reproductive performance, egg and larval quality, and lipid composition of females of the freshwater prawn <i>Macrobrachium rosenbergii</i> were investigated. Three isolipidic diets containing similar amounts of highly unsaturated fatty acids but varying levels of PL (0.8, 2.4 and 4.6%) were fed during 180 days to three groups of eight females originating from Thai ponds. No significant differences were observed for fecundity, egg size and hatchability, starved larvae size, and size, survival and tolerance to stress of 8 day-old larvae. Similarly, no major differences in the lipid composition of the midgut gland, ovaries and muscle tissue of females could be detected. Results...

Performance of <i>Macrobrachium rosenbergii</i> broodstock fed diets with different fatty acid composition OMA
Cavalli, R.O.; Lavens, P.; Sorgeloos, P..
The effect of linoleic acid (18:2n-6) and n-3 highly unsaturated fatty acids (HUFA) on the reproductive performance and offspring quality of the freshwater prawn <i>Macrobrachium rosenbergii</i> was evaluated in a 180-day trial. Three isonitrogenous and isolipidic diets containing different levels of fatty acids, high 18:2n-6 and n-3 HUFA concentrations, high 18:2n-6 and low n-3 HUFA, and low 18:2n-6 and n-3 HUFA, were fed ad libitum to three groups of six females. Fecundity was improved by the addition of higher amounts of 18:2n-6 (from 3 to 13 mg g<sup>-1</sup> DW). As a consequence of higher fecundity, smaller eggs were obtained most likely because the number of oocytes competing for a limited amount of yolk was higher. The...

Quantitative relationship of two viruses (MrNV and XSV) in white-tail disease of Macrobrachium rosenbergii ArchiMer
Zhang, Hj; Wang, Hm; Yuan, Jf; Li, Lj; Zhang, Jh; Bonami, Jean-robert; Shi, Zl.
Macrobrachium rosenbergii nodavirus (MrNV) and extra small virus (XSV) were purified from diseased freshwater prawns M rosenbergii and used to infect healthy post-larvae (PL) by an immersion method. Three groups of prawns were challenged with various combined doses of MrNV and XSV. Signs of white-tail disease (WTD) were observed in Groups 1 and 2, which had been challenged with combinations containing relatively high proportions of MrNV and low proportions of XSV. By contrast there was little sign of WTD in Group 3, which had been challenged with a higher proportion of XSV than MrNV. A 2-step Taqman real-time RT-PCR was developed and applied to quantify viral copy numbers in each challenged PL. Results showed that genomic copies of both viruses were much...

Reproductive performance of <i>Macrobrachium rosenbergii</i> females in captivity OMA
Cavalli, R.O.; Lavens, P.; Sorgeloos, P..
The breeding frequency, fecundity, egg hatchability, larval output and viability of pond-reared, mature <i>Macrobrachium rosenbergii</i> females were individually followed up during 180 d. Sexually mature prawns were maintained under controlled laboratory conditions (28.7 C and 12-h light/d) in a 190-L freshwater recirculation system and fed a formulated diet. Ovarian development, moulting and spawning events were checked daily. At least six consecutive moults were recorded for each of the 18 females. The duration of the intermoult period averaged 27.5 d and was not affected by ovarian development or spawning, but intermoult periods followed by spawning had significantly lower growth rates. From a total of 126 moulting events recorded, egg...

The state of the art of IFREMER in tropical aquaculture ArchiMer
Calvas, Jacques.
IFREMER, a French governmental agency, is engaged in research on tropical aquaculture since 1971, with the aims to develop new activities in French overseas territories and to export French technology to foreign countries. With 80 searchers and technicians the "Centre Oceanologique du Pacifique" is the main IFREMER's centre involved in tropical aquaculture. The research has been focused on the complete control of the whole cycle: constitution of broodstock, maturation and reproduction, larval rearing, and grow-out.

Variations in lipid classes and fatty acid content in tissues of wild <i>Macrobrachium rosenbergii</i> (de Man) females during maturation OMA
Cavalli, R.O.; Tamtin, M.; Lavens, P.; Sorgeloos, P..
This study describes the variations in total lipid, lipid classes and fatty acids in the midgut gland (MG), ovary, and muscle tissue of wild-caught <i>Macrobrachium rosenbergii</i> to elucidate the importance of these components during sexual maturation. Mature females were captured in the Mae Klong River, Thailand, from July to September 1998, and divided into five groups according to their ovarian development. Total lipid levels in the ovary increased with maturation, but no concomitant decrease in MG lipids was observed. Thus, the lipid requirements of the developing ovary are thought to be more dependent on the immediate ingestion of dietary lipid than on MG reserves. Higher proportions of neutral lipids (NL), mainly triacylglycerols (TG),...

Anousone Sisouvong; Chalor Limsuwan; Niti Chuchird; Sutee Wongmaneeprateep.
The effects of dietary Schizochytrium sp. supplementation on growth and survival rate of giant freshwater prawn (Macrobrachium rosenbergii) were studied. The prawns (approximate weight of 0.5 g/prawn) were fed with pelleted feed supplemented with Schizochytrium sp. at the levels of 0% (control group), 2.5%, 5.0%, 7.5% and 10.0%. Fifteen prawns were used for each treatment with the experiments being carried out in triplicate. Initial weight of the prawns was measured at the beginning of the experiment and after culturing for 50 days in suitable conditions, final weight, weight gain and survival rate of the prawns were recorded. The results showed that survival rates of the prawns were not significantly different regardless of levels of Schizochytrium sp....
