We encourage producers to use feed that is organically grown, and feed that does not contain primary catch. However, because the organic fish feed market is in its early stages, there is limited availability and an extremely high cost barrier. Therefore we do not require that fish feed be organic, and we will not offer CNG certification for the fish raised in a CNG operation. As organic fish feed becomes more available, we will revisit CNG fish feed standards. CNG draft standards prohibit fish feed that contains (or is) medications, hormones, or human or other animal waste.
