Species of Interest – fishes and invertebrates including selected exploited and non-exploited species identified as priorities.
Habitat – composition and complexity as they have direct effects on fish and invertebrate diversity.
How are we monitoring?
F/V Donna Kathleen – owned and operated by Capt. Tim Maricich and his family Donna and Tyler.
ROV Beagle – owned by TNC operated by MARE.
Taxonomic distribution and abundance plots (TDAPs) plot the geo-referenced occurrence of key species groups and landscape attributes at one-minute intervals over the area surveyed by the ROV. These plots provide managers with a timely snapshot of community structure inside and out of the new MPAs while more intensive frame-by-frame analysis of project imagery is conducted.
