  • Combines expertise of:
  • Fishing community
  • Academic scientists
  • Resource managers
  • Conducts data collection for

MPA monitoring and fisheries management

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

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

  • ver 225 miles and grew 5 inches in ~4 years

(1.25 inches a year). Copper Rockfish have been previously thought to move very little.
