Transcript Slide 1
Coastal Pelagic Trilogy • Biology and fisheries (Andrew Thompson – NOAA); historic perspective (Richard Norris – SIO); Lab: dissections and larvae. • CalCOFI (Tony Koslow -SIO). Lab on daily egg production method. • This week: assessment and management (Kevin Hill -NOAA), temperature corollary (Sam McClatchie -NOAA), economics (Sam Herrick - NOAA). Group Discussion. Next week: meet in A210 Readings are posted Projects & Partners March 1 2011 •Alexis and Jade –ICCAT and Bluefintuna •Daniel and Susanna –loggerhead ESA •Ali and Carolina –bearded and ringed seals ESA •Robin and Melissa –hydropower project •Karen and Zach –humpback ESA March 8 2011 •Lisa and Sara –gray whale ESA •Jaclyn and Katy–false killer whale ESA •Dominique and Ariana–bluefintuna ESA listing •Domingo, Min and Kristian–Klamath river dam removal Readings: “suggested background reading” 2 papers by Barb Taylor on “units to conserve” CPS: Ideas to Consider • Space and time are important; historic data provides an understanding cycles and is useful for future predictions • Estimating abundance of millions of schooling individuals requires additional techniques (acoustic and aerial surveys). • Environmental parameters (e.g., temperature) important corollaries. CPS Take-Home Messages • Long-term datasets are critical for understanding trends, relationships, cycles. • Change is fundamental to the dynamics of these species and so management must be adaptive; response times of may differ. • Precautionary Management is necessary to deal with uncertainty in the direction of change and importance of the species ecosystem role. HMS/Turtles Take-Home Messages •Approaches should be: – Holistic - taking into account all sources of mortality – Multilateral - unilateral management of HMS may not work; shutting down U.S. fisheries could be counterproductive – Creative – multiple avenues (economic, ecological, social) work
