To study potential mechanism(s) causing the reduced growth of the clam Venerupis philippinarum at the end of the production cycle, observed in the culture ponds at Zeeland Aquaculture in 2011, specific studies on eco-physiology and nutrient dynamics of individual clams were performed in the culture ponds during the production period in 2012. The study was divided in two sub-projects: Sub-project I: which focused on the uptake of the clam in terms of clearance rates and absorption efficiencies, Sub-Project II: focused on the internal nutrient fluxes of carbon, nitrogen and phosphorus, of the clams in the culture ponds in relation to food availability and environmental conditions, described in this report. |
