Drifters tell sludge story?

CANADA - A couple of objects have washed ashore around Kejimkujik National Parks Seaside Adjunct that have given the Friends of Port Mouton Bay some hard data to contribute to its scientific body of information, says member Ron Loucks.

Seabed drifters released by the Friends of Port Mouton Bay in January are starting to come ashore. This seabed drifter was found in Kejimkujik National Park in late April.

The group is campaigning against Aqua Fish Farms’ proposed expansion.

He said that they realize that as a group they have a lot of assets and knowledge about Port Mouton Bay.

They also know that data gaps exist and that they are in a crisis over the expansion of the salmon aquaculture, said Loucks.

He said they know fish waste settles to the bottom, but the question is: does it spread out over time?

Therefore, in January they put 29 seabed drifters in the waters near the proposed fish farm site in Port Mouton Bay.

A seabed drifter is a small parachute shaped piece of plastic with weight that allows it to sink to the bottom and rest lightly to drift with the currents, Loucks explained.

In a way, it emulates fish farm sludge, he added.
