Only in the last few years they are triploids, and I am pretty sure it is not all of them to this day.... Although they have been trying it for years they finally have figured out the survival rates to make it viable for a over all catch and take stocking program. The interior was the the start of the experiment.
And I think "fried" is the wrong word... Triploids are neither male or female.
The large majority of lakes on south Vancouver island are stocked with triploid... only the odd lake that they want breeding stock for doesn't get them. Even the cutthroat trout they stock are surprisingly.
but yes, fried isnt exactly the right word... hence the quotations. but they also stock all female trout which are sterile.
