Résumé : Since 1993, the New Caledonian shrimp industry has been faced with cold season mortality outbreaks of multifactorial origin. This pathology called “Syndrome 93” affects as well animals in grow-out ponds as broodstock after their transfer in maturation room, with up to 35% of mortality in 48 hours. From literature data and physiological studies on Litopenaeus stylirostris, several combinations of three abiotic parameters (temperature, salinity and feeding) have been tested during the breeders stocking period. This research allowed us to lower stress factors impact and to propose a transfer protocol which leads to an optimal physiological comfort of the animal. Results showed that survival rate is improved and spawning rates are twice higher. These findings have come up with a routine protocol of carrying out any transfer in a tank with water at temperature of 26°C, salinity of 26 ppt and no food supply during 48 hours. The use of this protocol in a commercial hatchery led to a significant broodstock survival improvement.
Depuis 1993, la filière crevetticole calédonienne est confrontée aux mortalités de saison froide dont les causes sont multifactorielles. Cette pathologie appelé « Syndrome 93 » affecte non seulement les animaux dans les bassins de grossissement, mais elle touche également les géniteurs après leur transfert en salle de maturation, les pertes pouvant atteindre 35% en 48 heures. A partir de la littérature et d’études physiologiques de la Litopenaeus stylirostris, différentes combinaisons de trois paramètres abiotiques (température, salinité et alimentation) ont été testés lors de la stabulation des reproducteurs en salle de maturation. Ces recherches ont permis de diminuer l’impact des facteurs de stress et d’établir un protocole de transfert des animaux dans les conditions de confort physiologique optimale. Les résultats montrent que la survie est améliorée mais que le pourcentage de pontes est également doublé. Il est maintenant recommandé pour tout transfert, de prévoir des bacs de réception dans lesquels l’eau est à la température de 26°C, la salinité à 26 ppt et de ne fournir aucune alimentation pendant 48 heures. L’application de ce protocole dans une écloserie privée a démontré un gain substantiel sur la survie des géniteurs.

Résumé : International audience
BACKGROUND: We aimed to assess, for the first time, the nature of the indoor air contamination of hospitals. METHODS AND FINDINGS: More than 40 volatile organic compounds (VOCs) including aliphatic, aromatic and halogenated hydrocarbons, aldehydes, alcohols, ketones, ethers and terpenes were measured in a teaching hospital in France, from sampling in six sampling sites--reception hall, patient room, nursing care, post-anesthesia care unit, parasitology-mycology laboratory and flexible endoscope disinfection unit--in the morning and in the afternoon, during three consecutive days. Our results showed that the main compounds found in indoor air were alcohols (arithmetic means ± SD: 928±958 µg/m³ and 47.9±52.2 µg/m³ for ethanol and isopropanol, respectively), ethers (75.6±157 µg/m³ for ether) and ketones (22.6±20.6 µg/m³ for acetone). Concentrations levels of aromatic and halogenated hydrocarbons, ketones, aldehydes and limonene were widely variable between sampling sites, due to building age and type of products used according to health activities conducted in each site. A high temporal variability was observed in concentrations of alcohols, probably due to the intensive use of alcohol-based hand rubs in all sites. Qualitative analysis of air samples led to the identification of other compounds, including siloxanes (hexamethyldisiloxane, octamethyltrisiloxane, decamethylcyclopentasiloxane), anesthetic gases (sevoflurane, desflurane), aliphatic hydrocarbons (butane), esters (ethylacetate), terpenes (camphor, α-bisabolol), aldehydes (benzaldehyde) and organic acids (benzoic acid) depending on sites. CONCLUSION: For all compounds, concentrations measured were lower than concentrations known to be harmful in humans. However, results showed that indoor air of sampling locations contains a complex mixture of VOCs. Further multicenter studies are required to compare these results. A full understanding of the exposure of healthcare workers and patients to complex mixtures of chemical compounds can then be related to potential health outcomes.
