This seminal publication was created by REEF and our collaborators at NOAA, ICRI, the United Nations Environment Programme, Caribbean Environment Programme, SPAW-RAC, and the over 40 participants of the 2010 Caribbean Regional Lionfish Workshop. The guide provides best practices for lionfish control and management, including control strategies, outreach and education, research, monitoring, legal considerations, and ideas for securing resources and partnerships. By following these best practices, resource managers can reduce the local impacts of invasive lionfish in marine protected areas and other places of ecological and economic importance. Available online as a PDF through the link below. Also available as an ebook. Spanish edition also available (email reefhq@REEF.org for more information).
