Composition en cires, triglycérides, protéines et sucres du mésozooplancton ArchiMer
Alayse-danet, Anne-marie; Daniel, Jean-yves; Le Coz, Jean-rene.
Analyses effectuées sur le zooplancton total des pêches verticales au WP2 et sur des animaux triés à partir des pêches horizontales (Campagne RCA sur les côtes Atlantiques du Portugal). On ne signale pas de différence significative entre la composition biochimique des populations du large et de la côte

Effect of chronic exposure to ammonia on alterations of proteins and immunoglobulins in sea bass (Dicentrarchus labrax) serum ArchiMer
Coeurdacier, Jean-luc; Dutto, Gilbert.
The relationship between serum protein, immunoglobulin concentrations and protein molecular weight profile (PMWP) alterations of sea bass (131.3 +/- 4.3 g) reared in sea water with sublethal concentrations of ammonia was studied over two periods totalling 116 days. During the exposure period (62 days) the first group (group 1) lived in sea water with 0.204 mg.L-1 unionized ammonia nitrogen equivalent to 12 % of the lethal concentration for 50 % of a population exposed for 96 h to ammonia (96-h LC50), whilst the second group (group 2) lived in sea water with 0.340 mg.L-1 UIA-N equivalent to 20 % of the 96-h LC50 of ammonia. Then, the two groups were left for a recovery period (54 days) in the same water as the control group (group 0). The determination of...

Temporal variability in the biochemical composition of sedimentary organic matter in an intertidal flat of the Galician coast (NW Spain) ArchiMer
Cividanes, S; Incera, M; Lopez, J.
Temporal variations and spatial distribution of sedimentary organic matter composition were investigated over a one year period in an intertidal flat of the NW Spain. Sediment samples were collected from 0 to 25 cm depth, every three months, from January 1997 to January 1998 at three tidal levels (high, medium and low). Changes in the elemental and biochemical composition were assessed to gather information on temporal and spatial fluctuations in quantity and quality of sedimentary organic matter potentially available to benthic deposit-feeder nutrition. Organic matter content was significantly higher at the medium tidal level, while minimum values were found at the high tidal level. The different biochemical classes of organic compounds exhibited...
