Benefits for aquaculture

Set against the background of potentially increasing volumes of vinasse and the low level of added value associated with this at present, vin2food also offers sustainable approaches for aquaculture by using the vinasse as a substrate for the production of zooplankton and phytoplankton, which can subsequently be processed to produce fish food.

One key advantage of aquacultures is that they can help counteract the overfishing of the oceans, while also providing a new source of nourishment. However, for the artificial breeding to be a success, large volumes of fishmeal are required to provide the fish with important nutrients. Breeding 1 kg of fish in aquacultures requires 1 to 5 kg of wild-caught fish, which is processed to produce fishmeal. As such, this approach itself puts increasing pressure on the already depleted stocks of fish living in the wild and thereby contributes to the world's oceans continuing to be overfished. The demand for fishmeal is growing on a global scale. This growth in demand is also being accompanied by price increases. As such, the production of zooplankton represents an economically interesting alternative.
