Resumo: 	The amylase and trypsin activity of the most important zooplankton species has been measured in the upwelling zone of the Spanish Sahara during the "Gibraltar ecophysiological cruise" of the oceanographic vessel Jean Charcot. The analysis of the results was carried out for the double purpose of demonstrating the regulation by the nutrition of the activities of digestive enzymes and utilizing these results to study the feeding behavior under the natural environmental conditions of an ecosystem.  With regard to its biological significance, the influence of the quality and quantity of food available has been demonstrated by a bouble experimental approach followed by a statistical one. Significant correlations were found between the specific amylase activity and the rates of ingestion and assimilation. An adaptation of amylase- and trypsin activity to the quantity and the quality of food available had been shown. This adaptation allows the organisms to maintain an optimum digestive efficiency. The statistical analysis of the in situ results shows the relationship between the digestive enzymatic activities and certain characteristics of the food (particles) available. [NOT CONTROLLED OCR]
