ABSTRACT:
Method and apparatus for harvesting and processing zooplankton and, in particular, for harvesting and processing euphausiids for subsequent use as a feed product for early stage juvenile or larvae feed or for a food product as an additive. The euphausiids are continuously harvested from coastal waters and dewatered. The dewatered product is passed to a heat exchanger to increase its temperature and, hence, to a digester where a desired level of enzymatic activity is obtained. The product is then held by a surge tank for subsequent transfer to a ball dryer where the product is dried at a relatively low temperature without destroying the stabilized enzymes created in the digester. The digesting step may be deleted in the event the end use of the product is for a food product.
