Abstract

After more than ten years of consistent vitamin/mineral supplementation, supplementation was suspended in three dolphinaria in March 1978. The hematological results in particular in November '78 and February '79 are the same or better than before, the Killer Whale included. The recovery of a beached Harbour Porpoise is remarkable. The only supplementation is Vitamin B1 and Calcium. It is argued that the addition of this mineral is essential. The animals are fed five different species of fish including squid.
