The number of minke whales in the North-East Atlantic is estimated to 87000 (with a 95% confidence interval of +-20000). From the models of the scientific committee of the Int'l Whaling Commision this results in an annual ecologically safe catch quota of approx 800. The total quota for '94 (and for '95) is 301.
