Overview Background Proof of Concept Study: Integrating mapping, trapping, mark-recapture –Dunnington et al. (NZJMFR 2005) –Geraldi et al. (CJFAS 2009) Application: Disposal Impact Study –O’Donnell et al. (MEPS 2007)

Seabed (Post-settlement) Processes - movements & mortality JUVENILE CRYPTIC disperse / migrate emerge ADOLESCENTS ADULT (SPAWNERS) LARVAE hatch POSTLARVAE transport Water column (Pre-settlement) Processes - larval drift & death Long-term Vision Linking Life Stage-specific Abundance Estimates

Seabed mapping a critical tool for habitat-specific abundance estimates & impact assessment Trap-based catch rates highly correlated with abundance. M-R analysis a powerful tool in translating catch into abundance, gains, loss estimates. Longer time series more robust. Approach can be tailored for different spatial scales and time-frames. Potential use in MPA assessment and environmental impact studies. Validating Trap-based Mark-Recapture Abundance Estimates with Dive Surveys Summary:

Movements Within Array Different Trap Same Trap

Efficient Relatively inexpensive Sample where divers & trawls can’t Catch data – reflect basic patterns Why Use Traps? The Problem With Catch Data: Don’t know how catch rates relate to abundance or dynamics. Not all traps are created equal. Lobstermen fish traps to catch lobsters.
