Evolution de la biomasse et de la physiologie du zooplancton sur la côte nord de Bretagne en relation avec l'échouage de l'Amoco Cadiz : résultats préliminaires pour la période du 16 mars au 20 mai 1978

First results about distribution and changes of biomass (dry weight and total soluble proteins), physiology (amylase, trypsin) and faunistic composition of zooplankton are reported for the two months period following the spill of AMOCO CADIZ on the Britany Northern coast. A shortage of biomass in the aber area is attributed to hydrocarbons. The low level of the mean value of biomasse on the North coasts, and the pecularities of estuarine station of the Lannion bay and of Trieux area are reported and discussed.
