  1. We Welcome! Bodega Marine Laboratory California Collaborative Fisheries Research Program

  2. I’ve been with CCFRP since the Introductions beginning! • Name • How are you connected to CCFRP? • Number of years involved in the project • Favorite marine animal

  3. Marine Life Protection Act (MLPA) • Passed in 1999 • Mandated the creation of a network of marine protected areas (MPAs) to protect diversity and ecosystem function

  5. California Collaborative Fisheries Research Program (CCFRP) • Fishery-independent study • Combines expertise of: • Fishing community • Academic scientists • Resource managers • Conducts data collection for MPA monitoring and fisheries management

  6. Goals of CCFRP • conduct scientifically sound research to better inform resource managers • provide rigorous baseline/monitoring data for the evaluation of MPA performance • better understand nearshore fish stocks and the ecosystems upon which they rely • collaboratively work with local fishing communities to collect fisheries data

  27. Highlights 2017 Season

  29. BODEGA BAY, THURSDAY, SEPTEMBER 28 2017 VOL. 1 FREE Copper Rockfish travels 225 miles! by Bodega Marine Laboratory A Copper Rockfish (12 inches) was initially tagged in Piedras Blancas MPA on 8/20/2013. It was then recaptured near Stewarts Point (17 inches) on 9/28/2017. That means it travelled over 225 miles and grew 5 inches in ~4 years (1.25 inches a year). Copper Rockfish have been previously thought to move very little.
