Continuous plankton rearing system - with continuous circulation and filtering between main and auxiliary tanks and continuous supply of nutrient enriched water

摘要

Water with distributed food is continuously fed to a main cultivation tank for plakton. The cultivation of the plankton is carried out in the main tank in a synthetic cultivation water. There is also continuous feeding of the plankton together with the synthetic cultivation water from the main tank to an auxiliary tank. There is continuous drawing off of th synthetic cultivation water from the auxiliary tank without taking off plankton. Part of the drawn off water is continuously recirculated to the main tank and the plankton is collected from the auxiliary tank. The synthetic cultivation water drawn from the auxiliary tank is filtered before the recirculation to the main tank.
