6 Project initiated 2004 under grant from Suffolk County, L.I. legislature Funding $1.8 M to support restoration project

7 . Goal over 4 Years to Infuse 50 Million Scallops into Peconic Bay

8 Project Managed by Cornell Cooperative Extension (CCE) and Long Island University

9 Long Island University Data Collection Data Collection –Spat collectors Technical monitoring Technical monitoring –Genetics –Water Quality –Food Supply –Survival Rate

10 Sanctuary Markers

11 Spat Collectors Catch Natural Spawn

12 Counting Spat

13 Cornell Cooperative Extension Algae Algae Hatchery Hatchery Nursery Nursery Grow out Grow out

14 Algae Algae CCE /SPAT Projects

15 Built Algae Room for SeaCap System Built Algae Room for SeaCap System One of only 10 operating in the U.S. One of only 10 operating in the U.S. SeaCap System SeaCap System

16 SeaCap System

17 –Major thrust on spawning scallops but also clams & oysters –Hatchery SPAT hatchery supplements CCE hatchery SPAT hatchery supplements CCE hatchery 16 conicals for larval stage 16 conicals for larval stage

18 Built Nursery in 2005 Scallop Nursery

19 Nursery Nursery –Continuous drum filtration supplements bag filters. –Post-set in sieves located in raceways. –Ongoing raceway maintenance

20 Spatkin Bridles Goose Creek Nursery

21 Scallop Barge

22 Operational Barge

23 Orient Harbor Grow out Submerged buoy lines-200 Meters each in Orient Harbor. 8 Submerged buoy lines-200 Meters each in Orient Harbor. –Allows navigation 6 & 12mm lantern nets 6 & 12mm lantern nets 3-week maintenance cycle 3-week maintenance cycle Barge-serviced Barge-serviced

24 Long line Design lb mushroom anchors 1

25 Deploying Long Lines

26 Stocking 6 mm Lantern Nets 200 per tier

27 Attaching Nets to Long Line

28 Nets serviced with star wheel

29 Stocking 12 mm Nets for winter

30 12 mm Lantern Nets 35 scallops per tier

31 Lessons Learned in 2006 Lessons Learned in 2006 East Hampton hatchery supplied 750,000 seed. Did not hit 10 million scallop seed goal for 2006 Did not hit 10 million scallop seed goal for 2006 Post set issue lost 80% of juveniles Due to dissolved oxygen and secondary cilliated protozoan infestion. Need for alternate nursery as backup, better water supply.

32 Lessons Learned in 2006 Lessons Learned in 2006 Use like metals, no mixing galvanized with stainless Mooring lines shifted -500 lb anchors 4 yr project -mooring lines must be removable Kinks to be worked out on long line system.

33 Continuing Education of SPAT Volunteers over the Winter Months
