Infectious diseases are mostly explored using reductionist approaches despite repeated evidence showing them to be strongly influenced by numerous interacting host and environmental factors. Many with a complex aetiology therefore remain misunderstood. By developing holistic approach tackle the complexity of interactions, we decipher intra-host interactions underlying Pacific oyster mortality syndrome affecting juveniles Crassostrea gigas, main species exploited worldwide. Using experimental...
Successive disease outbreaks in oyster (Crassostrea gigas) beds France have resulted dramatic losses production, and subsequent decline the oyster-farming industry. Deaths of juvenile oysters been associated with presence a herpes virus (OsHV-1 μvar) bacterial populations genus Vibrio. Although pathogenicity OsHV-1 μvar, as well several strains Vibrio has demonstrated by experimental infections, our understanding complexity infections occurring natural environment remains limited. In present...

Abstract Aim The spread of non‐indigenous species in marine ecosystems world‐wide is one today's most serious environmental concerns. Using mechanistic modelling, we investigated how global change relates to the invasion European coasts by a non‐native invertebrate, Pacific oyster Crassostrea gigas .

Growth and maturation of female snow crab (Chionoecetes opilio) in the northwestern Gulf St. Lawrence were elucidated using carapace size-frequency distributions, indices molting activity, ovarian mass, laboratory field measures growth per molt. Females develop three major stages: immature, with narrow abdomen no detectable ovaries; prepubescent, previtellogenic followed by vitellogenic adult, broad reproductive capability. Additionally, there is an ephemeral pubescent stage represented...

We grew mussels ( Mytilus edulis ) under two different food regimes and eight population density levels to estimate the joint effects of biomass on their growth survival determine shape biomass–density B–N) relationship. Mussels were reared for 22 months, between December 1994 October 1996, in 1‐L experimental chambers supplied with natural seston. Growth shell length, individual wet mass ash free dry m decreased decreasing availability increasing density. Survival was negatively correlated...

Feeding strategies and digestive capacities can have important implications for variation in energetic pathways associated with ecological economically traits, such as growth or reproduction bivalve species. Here, we investigated the role of amylase processes Crassostrea gigas, using vivo RNA interference. This approach also allowed us to investigate relationship between energy intake by feeding gametogenesis oysters. Double-stranded designed target two α-amylase genes A B was injected into...
The magnitude of an epidemic depends on host susceptibility to the disease, a trait influenced by genetic constitution and its environment. While basis disease is often associated with immune capacities, environmental effects generally reflect complex physiological trade-offs. We suggest here that in case obligate pathogens whose proliferation cellular machinery (e.g. viruses), directly growth. To test our hypothesis, we focussed viral affecting ecologically relevant model exploited...
