Stockage et transport des crustacés vivants ArchiMer
Chartois, Herve; Latrouite, Daniel; Le Carre, P.
Fishing and trade of living crustaceans are dynamic commercial sectors in France. 25 000 tons of local or imported crabs, lobsters , crawsfishes are yearly treated. Based upon a literature review and fishmongers interviews, this study describes the current pratices and problems associated to live crabs and lobsters storage. Supply conditions of live crustaceans, marketing networks, and biological, ecological and physiological characteristics of crustaceans were discussed. Morever, storage facilities, their operating rules and factors affecting the survival rate under storage and transportation conditions were reviewed.

Toxicity of ammonia to turbot juveniles: I. effects oil survival, growth and food utilisation ArchiMer
Person-le Ruyet, Jeannine; Delbard, Christine; Chartois, Herve; Le Delliou, Herve.
Long-term effects of constant exogenous ammonia concentrations were investigated in two different batches of turbot juveniles (53 and 73 g) under controlled environmental and feeding conditions. Over the 84-day experiments, ambient un-ionized ammonia (UIA-N, NH3) concentrations were steady (coefficient of variation, 12-16 %) and water pH range was 7.88-7.99. Survival was maximum up to 0.33 mg.l(-1) UIA-N and at 0.73, 50 % mortalities were observed on day 52 (73 g) or day 77 (53 g). No-growth concentration was 0.73 mg.l(-1) UIA-N in the two groups and the 84-day lowest-observable-effect concentration range 0.14-0.33 mg.l(-1). In the most tolerant group (53 g), the 84-day no-observable-effect concentration was 0.14 mg.l(-1) UIA-N. The estimated 28-day...
