This species has been nominated as among 100 of the "World's Worst" invaders

The great trout debate...

 

brown trout: Salmo trutta has been introduced around the world for aquaculture and stocked for sport fisheries. 

 

Brown trout have been implicated in reducing native fish populations (especially other salmonids) through predation, displacement, and food competition (Taylor et al. 1984, in Fuller, 1999).

 

It is a popular angling fish, particularly in the Mpumalanga Highlands. But this species has been nominated as among 100 of the "World's Worst" invaders.

My brother would be most interested in all this 'fishy business'! :) He's big into trout fly fishing. Interesting to read about all this.
