Book Description
Killer whales are found in all oceans of the world, but nowhere are they better known than in the coastal waters of Washington, British Columbia, and Southeastern Alaska, where 25 years of study have yielded many surprising discoveries about their natural history. One of the most remarkable is that two genetically distinct forms of killer whales reside in these waters. The two groups of whales do not associate and each leads a completely different lifestyle. Residents specialize in a diet of salmon and other fish, while transients are hunters of seals, sea lions, porpoises, and even large whales. Enigmatic and elusive, these mammal-hunting whales travel in small groups, often moving unpredictably. Transients contains the latest information on the natural history of transient killer whales, including their feeding habits, social lives, and distribution patterns. It also includes photographs of and notes on over 200 individual whales. Numerous sidebars contain interesting observations on encounters with transients as well as information on how and where to best watch them.

Book Description
"On April 30, 1994, Public Law 103-238 was enacted allowing significant changes to provisions within the Marine Mammal Protection Act (MMPA). Interactions between marine mammals and commercial fisheries are addressed under three new sections. This new regime replaced the interim exemption that has regulated fisheries-related incidental takes since 1988. Section 117, Stock Assessments, required the establishment of three regional scientific review groups to advise and report on the status of marine mammal stocks within Alaska waters, along the Pacific Coast (including Hawaii), and the Atlantic Coast (including the Gulf of Mexico). This report provides information on the marine mammal stocks of Alaska under the jurisdiction of the National Marine Fisheries Service"--Preface.
