Conclusions

Photo credit: C. Parsons

• Marine reserve network• TSER established 2001• RNA established 2007

• Species capacity to rebound• Burton et al. 2005• Spawning documented 2009• Population indices?

• Connectivity patterns: betterunderstanding.

• Population w/in DRTO/RNA & FSA site w/in TSER

• Acoustic tagging TSER funded in 2010.

• Expand efforts on black grouper.

• Continue tracking through 2011.

• Other RH FSA sites….Yellowtail? Gray? Cubera? Dog? Deeper habitat?

• Migratory ability of reef fish?
