ALTERNATIVE MANAGEMENT ACTIONS

Based on available information, vessel activity may have been a factor contributing to the movement of whales from Glacier Bay in 1978 and 1979. Alternatives available to manage vessel traffic (assuming increased traffic has had or will have an adverse effect on humpback whales) include:

1. Total closure of Glacier Bay to all vessels.

2. Closure to all vessels during the whale season.

3. Closure to all vessels during part of the whale season.

4. Total closure to all but certain classes of vessels—e.g., cruise vessels charter vessels fishing vessels

5. Seasonal closure to all but certain classes of vessels—e.g., cruise vessels charter vessels fishing vessels

6. Partial season closure to all but certain classes of vessels—e.g. cruise vessels charter vessels fishing vessels

7. Alternatives 4, 5, or 6 with limitations on total numbers of vessels of various classes given access

8. Alternatives 4, 5, 6 or 7 with restrictions applying only to certain areas of the Bay

9. Establishment of a ceiling for all vessels or certain classes of vessels during all or part of the whale season

10. No restrictions on access but certain activities prohibited or limited to certain areas or vessel classes—e.g.: establish traffic lanes and permit "deliberate" whale-watching only by a few trained and licensed charter-boat operators.

11. No restrictions.
