SYstème de BIOmétrie Larvaire de bivalves par analyse d'images ArchiMer
De Pontual, Helene.
SYBIOL, SYstem of BIOmetry of Larvae by image analysis, has been designed for measuring larvae of bivalves in a semi automatic way. The main interest of this tool is to provide more information with the extraction of parameters such as area or equivalent diameter. Our purposes are to describe and evaluate the system which is now operational and used in routine in the mollusc hatchery of Argenton.

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...

Traitement par lagunage a haut rendement algal (LHRA) des effluents piscicoles marins recycles: évaluation chimique et écotoxicologique ArchiMer
Deviller, Genevieve.
World aquaculture is a fast growing activity and the control of its waste becomes a key issue. Compared to traditional systems, recirculating systems allow to reduce replacement water and waste volumes. Nevertheless their effluents are more concentrated in dissolved nutrients (nitrate, phosphate). The high rate algae pond (HRAP) is one of the possible treatment technique to remove those nutrients. During this work, three rearing systems: one recycled, one recycled with HRAP and one open as a standard, were operated for one year to assess the impact of: (1) the reuse of treated effluent on survival, growth and nutrition of sea bass (2) the rearing system on fish health using multibiomarkers and trace metals accumulation responses and (3) best conditions for...

Variation de l’accumulation du lindane chez les alevins de <Liza ramada> OceanDocs
Masmoudi, W.; Romdhane, M.S.; Kheriji, S.; El Cafsi, M..
Pendant la saison printanière de recrutement maximale (avril/mai2000) des alevins de Liza ramada , nous avons effectué 4 campagnes de pêche au niveau de l’embouchure de canal « Khélij ». Les alevins de cette espèce ainsi collectés ont été repartis en trois classes de taille (classe I :19,4  1,3 mm ; classe II : 45,5  5,3 mm et classe III : 63,2  6,3mm) dans le but d’y analyser les résidus du lindane (  HCH ), un pesticide organochloré. Nos résultats ont révélé des concentrations de ce résidu chutant de 57,42  12,49 à 12,67  3,27 ng/ g de graisse en passant de la classe I à la classe III. Cette diminution est probablement due à une amélioration avec l’âge des capacités métaboliques de l’espèce vis à vis du contaminant. D’un autre côté, Liza...

Variations des activites digestives en fonction des facteurs du milieu chez les crustaces ArchiMer
Galgani, Francois; Benyamin, Y; Vanworhmoudt, A; Cecaldi, J.
Proteolytic enzymes of hepatopancreas of six species of peneids (Penaeus kerathurus, P. japonicus, P. monodon, P. stylirostris, P. merguiensis and P. vannamei ) have been studied. Some of their physiological variations have been characterised. Increase in acclimation temperature of crustaceans enhances increase of specific activities of proteases. Variations of salinity does not modify specific activities, nor quantities of trypsin, nor electrophoretic patterns of these different proteases.
