After 12,000 pounds of ghosts nets were found during Kaneohe Bay's restoration, officials discussed their discovery and future clean up plans.

We now know they have been sitting on the reef for at least a year and a half, and according to Hawaii Pacific University and the Ocean Voyages Institute, they are a mixture of fishing and cargo nets. Some nets are from illegal fishing. 

"If a plane or ship comes close to an illegal fishing vessel they cut all the nets because they don't want any proof on the ship that they've been fishing because they can be seized and fined, etc." said Mary Crowley, of the Ocean Voyages Institute.

Researchers say most of the nets are made of the same plastic that makes up your yogurt containers and milk jugs.

The focus now -- funding future clean-ups and finding ways to manage the trash.
