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.

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.
