1 2003 Status & Trends Triennial Fish Monitoring Update to RMP Fish Committee Jennifer Hunt, Ben K. Greenfield, Jay A. Davis SFEI Marco Sigala, Cassandra Roberts, Rusty Fairey Moss Landing Marine Labs Dave Crane, Kathleen Regalado, L.Nguyen, Gary Ichikawa CDFG

2 2003 Status & Trends Triennial Fish Monitoring Status and Trends –7 species –Added PBDE analysis for S&T species –Looked at As in 5 individual leopard sharks & 3 smoothound sharks –Looked at MeHg in 9 individual leopard sharks and 9 individual smoothound sharks –We now have time series data from

3 2003 Results – Status & Trends Some Good News All S&T fish below the Screening Value (SV) (30 ng/g ww) for chlordanes Only 1 sample exceeded DDT SV (100 ng/g ww) (white sturgeon – South Bay) Dieldrin SV (2.0 ng/g ww) only exceeded for white croaker (45%) and white sturgeon (50%)

4 69% of S&T samples exceeded Hg SV (0.2 ug/g ww) 86% of S&T samples exceed Aroclor SV (10 ng/g ww) 2003 Results – Status & Trends Some Not So Good News

5 PBDEs (ng/g ww) 2003 ND=7ND=2 ND=1

6 Pilot Study 2003 Preliminary screening 38% of samples exceeded the Aroclor SV 43% of samples exceeded the Hg SV

7 DDTs Lipid Weight

8 Chlordanes Lipid Weight

9 Data are standardized to a 55 cm fish Hg in Striped Bass

10 Trends Summary Evidence of decline in lipid weight concentrations for DDTs and Chlordanes in most fish species High variability in PCB data No long-term trend in striped bass Hg No long-term trend in sturgeon Se

11 2006 S&T Fish Project Fish Committee meeting Dec 19 th to decide sampling strategy Spring/Summer 2006 – begin sampling Spring 2007 – Data to SFEI November 2007 – Final Report
