Fishermen Concerned About Tidal Power

Fishermen in the Bay of Fundy are expressing rising concern about the placement of tidal turbines in the Bay of Fundy. See article.

Whale professionals should also be focusing on this eventuality as well, since critical cetacean habitat like Head Harbour Passage at the mouth of the Bay of Fundy is being targeted for possible massive placement of turbines. In relative terms this will make LNG tankers entering Passamaquoddy Bay look like minor annoyances. Large numbers of turbines in Head Harbour Passage will, without any doubt, change the ecological dynamics there and interfere with vital foraging habitat used by fish, birds, and mammals as well as traditional fishing grounds.

It is possible to arrange placement so that impacts can be minimized, but it is doubtful that developers will incorporate this into their plans since they all seem to be obsessed with the massive "farm" approach, rather than ecologically friendly development that will benefit coastal communities.

  1. Thanks for posting this, Art. Another issue perhaps more important in tidal rivers than the Bay of Fundy, is that the amount of energy withdrawn from the water in a river - 15% it is postulated for the Bagaduce Narrows proposal for the Bagaduce River in Maine - apparently means the river will be slowed by 15%, which has major implications for nutrient transport and many other things.

    Of course I may be entirely in error on the meaning of "15% Energy Withdrawal" from that river by the turbines. But certainly the laws of physics apply...
