Environmental Assessment for a Regulatory Amendment to Reapportion Total Allowable Catch of Atka Mackerel and Reduce Fishery Effects on Steller Sea Lions; Change in Atka Mackerel Interim

January 19, 1999

This final rule would implement regulations that divide the Atka mackerel total allowable catch (TAC) specified for the Aleutian Islands Subarea (AI) into two seasonal allowances; reduce the percentage of Atka mackerel TAC harvested from Steller sea lion critical habitat (CH) over a 4 year period in the Western and Central Districts of the AI; and extend the seasonal no-trawl zone around Seguam and Agligadak rookeries in the AI Eastern District into a year-round closure.

The purpose of this action is to avoid significant fishery-induced localized depletions of Atka mackerel, a primary prey species for Steller sea lions in the Aleutian Islands; and avoid potential jeopardy to the continued existence of Steller sea lion populations and their critical habitat through excessive removal of prey. In 1990, the Steller sea lion (Eumetopias jubatus) was designated as a threatened species under the Endangered Species Act of 1973.
