Just a couple of fish related stories of note. No comments pretty much self explanitory.

Averill Baker also has a new article.

Here is an interesting study or overview into developing the tidal power in the Strait Jacket of Belle Isle in conjunction with a fixed link bridge. There is even a power Point Presentation if you have the right add on.

A typical caisson with 20 paddlewheels will create about 10 MW of power from a current of 1 m/s. The average flow rate in the Minas Channel in the Bay of Fundy is about 6 m/s. In the Strait of Belle Isle, it's about 2.5 m/s but it is 20 km wide. I estimate that 5 plus Giga-Watts of power can be extracted from the Minas Channel. I estimate 50 Giga-Watts of green power energy to be extracted from various locations throughout the Bay of Fundy. In the Strait of Belle Isle, which separates the island of Newfoundland from mainland Canada, I estimate 10 Giga-Watts plus can be generated from the tidal current.

An additional feature of these tidal power caissons is that they can be aligned to form the foundations for a bridge. In the Strait of Belle Isle, this would provide a fixed link between the island of Newfoundland and the Labrador coast; similar to PEI's Confederation bridge, except that this bridge would create green power energy forever.
