Marine mammals and humans have co-existed on this planet for several hundred thousand years. Both rely heavily on the exploitation of marine resources, though whales, dolphins, and pinnipeds have been doing so for much longer, roaming the oceans for millions of years, long before the emergence of modern humans (Hoelzel 2002). It is not surprising that, when there is a “new kid on the block,” co-existence is not always very peaceful, and many of the encounters between humans and marine mammals result in a variety of conflicts.


This chapter is adapted from “Competition between Marine Mammals and Fisheries: Food for Thought” published by The Humane Society of the United States/Humane Society International.
