Acquisition of susceptibility to Vibrio penaeicida in Penaeus stylirostris postlarvae and juveniles ArchiMer
Goarant, Cyrille; Regnier, France; Brizard, Raphael; Marteau, Anne-laure.
Vibriosis is a major disease problem in shrimp aquaculture, affecting all developmental stages, from larvae in hatchery tanks to juveniles and broodstock in growout ponds. However, bacterial strains responsible for vibriosis in the successive stages are usually considered to be different, and virulence specificity has been reported both at the species and at the stage levels. The so-called « Syndrome 93 » is a seasonal juvenile vibriosis caused by Vibrio penaeicida which affects Penaeus stylirostris in growout ponds and broodstock tanks in New Caledonia. This pathology does not cause any mortality in hatchery or nursery phases. An experimental infection design using balneation of postlarvae and early juveniles in V. penaeicida suspensions was used to...

Combined effect of temperature and salinity on osmoregulation of juvenile and subadult Penaeus stylirostris ArchiMer
Lemaire, Pierrette; Bernard, Eric; Martinez-paz, J; Chim, Liet.
In New Caledonia, the "syndrome 93," which results in mass mortalities of farmed shrimp Penaeus stylirostris, occurs during the transitional and the cold seasons. The transitional season is characterized by an important fall in the average water temperature from 28 to 19 degreesC in 2 weeks. Besides this marked temperature fall, there are also nyctemeral temperature changes of up to 7 degreesC in 12 h. The cold season is characterized by an average water temperature of 19 degreesC with extreme lows of 14 degreesC. The objective of this study was to determine the effect of temperature and its variations on the osmoregulatory capacity of juvenile (7-10 g average weight) and subadult (25 g average weight) shrimps subjected to conditions of different salinity....

Etude des tris précoces en élevage de crevettes P. stylirostris dans un objectif de sélection génétique. Février à Juillet 2000. ArchiMer
De Decker, Sophie.
Schemes optimisation for genetic improvement for growth of Penaeus stylirostris requires the development of technologies for grading shrimps easily. This work shows that bar and mesh graders are very suitable for early selection at post-larval stages, as long as early growth is heritable. Experimental data sets lead to the equations which give the grading weight as a function of the dimensions of the graders. Mesh graders which allow an earlier selection than bar graders (PL19 instead of PL25) open a new way to implement experimental selection into production hatcheries.

Etude expérimentale de l'influence de deux stress environnementaux sur les défenses immunitaires et la résistance à la vibriose de la crevette Penaeus stylirostris ArchiMer
Gangnery, Aline.
Cette étude a pour objectif de mesurer chez la crevette Penaeus stylirostris l'effet de deux stress environnementaux, ammoniaque et hypoxie, sur les défenses immunitaires (hémocytes et prophénoloxydase) et la résistance à l' infection par la bactérie Vibrio penaeicidae. Les crevettes, sélectionnées en stade C du cycle de mue, ont été soumises pendant 24 heures à plus ieurs doses d'ammoniaque N.NH3 ( 1, 1 .5, 2, 2.5 et 3 mg/l) ou placées en situation d' hypoxie (1 ppm vs 6ppm en normoxie). L'effet du stress a été évalué à 24 h par la mesure de la capacité osmorégulatrice ainsi que les paramètres immunitaires. Les résultats montrent que l'ammoni aque à 3 mg N.NH3/I induit une diminution significative du nombre total des hémocytes, cependant que l'activité de...

Expériences 97 sur l'influence des sédiments du bassin d'élevage sur la physiologie de Penaeus stylirostris ArchiMer
Cochard, Jean-claude.
Les crevettes pénéides maintenues captives dans des cages posées sur le fond des bassins d'élevage subissent un stress dû au sédiment qui peut être évalué par la comparaison entre la valeur de la pression osmotique de leur hémolymphe et celle des crevettes libres du même bassin. Les objectifs des travaux réalisés à la station de Saint-Vincent (SASV, Nouvelle Calédonie) étaient de confirmer la variabilité spatiale de l'intensité du stress et de rechercher dans les sédiments un indicateur physique ou chimique corrélé à ce stress. Des lots de 25 à 30 crevettes de 13,2g, pêchées à l'épervier, ont été placés dans des cages de grillage métallique déposées en 12 points du bassin d'élevage. Les cages ont été relevées au bout de 24 heures et la pression osmotique...

Histological abnormalities related to mortality in penaeid shrimp (Penaeus stylirostris) reared in New-Caledonia ArchiMer
Berthe, Franck; Legroumellec, Marc; Haffner, Philippe; Renault, Tristan.
Outbreaks of mass mortality occurred since 1993 in penaeid shrimp (Penaeus stylirostris) reared in New-Caledonia. Since then, the disease, called "syndrome 93" (S93) has inflicted serious losses (60 to 100%) during the cold period and thus must be considered as an economically significant disease.

Microsatellite-associated heterosis in hatchery-propagated stocks of the shrimp Penaeus stylirostris ArchiMer
Bierne, Nicolas; Bezuart, Ivan; Vonau, Vincent; Bonhomme, François; Bedier, Edouard.
Correlation between DNA microsatellite heterozygosity and growth rate was investigated in two hatchery-propagated stocks of the shrimp Penaeus stylirostris, which had been genetically isolated from wild founders for 17 generations, and from each other for five more generations. presumed demographic history of these populations suggested that they were maintained at small effective population sizes. and this was confirmed by significant changes in allelic frequencies between the two stocks. Despite a small sample size (n = 60) and a small number of loci screened, a significant positive correlation was detected between microsatellite tri-locus heterozygosity and growth rate in one of the two stocks (r = 0.3, P = 0.02). In the other stock (n = 48), the...

Shrimp aquaculture in New Caledonia ArchiMer
Galinie, C.
In New Caledonia, there is no indigenous shrimp species for commercial aquaculture and it is necessary to control the complete cycle in captivity. Since 1973 and the creation of the Station d'Aquaculture de Saint-Vincent (S.A.S.V.), a joint project between IFREMER, France-Aquaculture and the territory of New Caledonia, nine species have been tested and for one of these, P. stylirostris , (introduced in 1980), we are now in a commercial scale production with the tenth generation obtained in captivity.

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.

Traitement des crevettes contre le noircissement .Mise au point d'une ligne de traitement ArchiMer
Chantreau, Patrick.
Once fished, the shrimps must be cooled quickly in water cooled in order to slow down all chemical and bacteriological activities. In addition, in order to avoid blackening (mélanose) shrimps (céphalothorax and legs) it is necessary to treat those with an antioxydant product. The product currently used to inhibit this enzymatic change is the soda niétabisuifite (Na-> S7 O5), until now, after being fished. the shrimps were directly soaked in a cooled water tank, containing the pesticide. The solution of treatment was progressively prepared needs. The concentration of this one was approximately 2 to 3% of métabisulfite, that is to say 6 to 9 G of SO2 per liter for a starting product containing 320 G of SO2 approximately. In order to preserve a good...
