The four charts in the next page represent the number of whales killed in the period between 1950 and 1985. It is very clear that the larges type of whales “Blue Whales” was the preferable type to be killed. Starting on 1950, approximately 8,000 Blue whales were killed compared to the 4,000 smaller size Sei whales killed at that period taking into account the ratio of three to one between the Blue whales and the Sei Whales specie. This rate kept decreasing very sharply due to the massive exploiting of Blue whales to almost zero at 1970. As the largest mammal on earth almost extinct, other smaller size whales become the only option to hunters. The Fin whales for example in char two was at very high saturated rate of approximately 35,000 whales killed every year starting from 1955 up to 1960. This high number was a very clear indication of overcoming the shortage in large Blue whales with smaller sizes at that period. As the number start decreasing early on 1960, the Sperm and Sei whales, which smaller than the Fin whales, were peaking at 30,000 whales per year between 1965 and 1970.
