Banning all Toxic Antifoulants
Community Awareness
700 tons of Sediments, approximately 30,000 Dollars
The cost of only .005 % of the fishing industry
Tributlytin
Kills the Burrow organisms
Alters fishing activities
Causes Endochrine Disruptions
Dredging = Short-term POTENTIAL Consequence = Long-term Solution

Some organisms may suffer immediate death but in the future the population will not suffer from Tributlytin
Potential Negative Effects of Dredging
Death of Burrow Organisms
Turbidity Releases
Change of Port Activity
Dredging Consequences
