Abstract:

In this article, we respond to concerns raised by Brooks and Jones (2008) about recent advances in sea lice and salmon population dynamics in the Broughton Archipelago, British Columbia. We show that the assessment by Brooks and Jones (2008) is thoroughly mistaken and that their conclusions are based on a combination of obfuscation, misrepresentation, and fundamental misunderstandings. The extinction hypothesis is not actually a hypothesis at all, but rather an inevitable consequence of sustained population decline. Local extinction of Broughton Archipelago pink salmon can be prevented if population declines are turned around, and the data and models suggest this can be achieved if the infestations are stopped. We have organized our responses in an itemized manner according to the headings and subheadings in Brooks and Jones (2008).
