Selection and characterization of potential probiotic bacteria for Litopenaeus stylirostris shrimp hatcheries in New Caledonia

In New Caledonia, shrimp hatcheries are confronted with mass mortality in the larval stages, a phenomenon poorly understood as no specific causative agent has been identified. This has resulted in an excessive use of prophylactic antibiotics, althoug...

Complementarity of Rotating Video and Underwater Visual Census for Assessing Species Richness, Frequency and Density of Reef Fish on Coral Reef Slopes

Estimating diversity and abundance of fish species is fundamental for understanding community structure and dynamics of coral reefs. When designing a sampling protocol, one crucial step is the choice of the most suitable sampling technique which is a...

Stylog : base de données pour le suivi des élevages de crevettes de Nouvelle-Calédonie

In order to have a standardised database gathering most information on New Caledonian prawn farms a software, called “Stylog-module ferme”, was developed and implemented by Ifremer with the help of shrimp farmers. Data recording results in more t...

Fishers' perceptions as indicators of the performance of Marine Protected Areas (MPAs)

Vibriosis induced by experimental cohabitation in Crassostrea gigas: Evidence of early infection and down-expression of immune-related genes

The understanding of reciprocal interactions between Crassostrea gigas and Vibrio sp., whether these be virulent or avirulent, is vital for the development of methods to improve the health status of cultured oysters. We describe an original non-invas...

Vibrio nigripulchritudo monitoring and strain dynamics in shrimp pond sediments

Aims: A description of bacterial pathogens in shrimp ponds is necessary to understand their pathogenesis. Vibrio nigripulchritudo was shown to contain saprophytic and pathogenic strains among New Caledonian isolates. We established a method to map th...

Bonamia-ostreae induced mortalities in one-year old European flat oysters Ostrea edulis: experimental infection by cohabitation challenge

Bonamiosis is a parasitic disease (causative agent: Bonamia ostreae) affecting the European flat oyster Ostrea edulis, responsible for a drastic decline in the aquaculture production of this oyster species. Therefore a selective breeding program for ...
