- 9. Pacific herring Engraulis mordax photo by Frank Varga photo by Ground Truth Trekking We have major challenges Herring 1. We don’t know why herring are declining. • Habitat loss • PredaEon • PolluEon • Prey • Disease • Disturbance 2. We don’t know populaEon status of surf smelt or sand lance. • How many are there? • How many do we need?
- 10. We do know habitat ma]ers • Herring populaEon is 2x more stable because of habitat diversity. • Shoreline development degrades forage fish spawning habitat. • Higher egg mortality • Higher temperatures • Loss of fresh sediment supply
- 11. What acLons are we taking? • Puget Sound Partnership is tracking Pacific herring as an indicator of ecosystem health. • Puget Sound InsLtute has convened a panel of forage fish experts to fill key informaEon gaps using exisEng data. • Puget Sound Ecosystem Monitoring Program has prioriEzed measuring sand lance and surf smelt abundance. • Dept of Fish & Wildlife is taking a precauEonary approach with fisheries management. • Dept of Fish & Wildlife requires HPA permit to develop shorelines.
- 12. What more should we be doing? 1. Collect abundance data for surf smelt and sand lance 2. EsEmate the abundance of surf smelt and sand lance using exisLng data 3. Determine the limitaEons to herring recovery using exisLng data 4. Collect biological informaEon 5. Improve habitat protecEon regulaEons 6. Limit fisheries harvest 7. Monitor predators and prey
