Was browsing a forum when I came across a post about this report . It is all about trout conservation and really emphasises habitat over stocking.
It gives and example of the three categories that can cause threats to populations of brown trout: harvest, stocking and Environmental degradation. Essentially the Kelvin has threats from all three of these factors what with anglers killing too many fish, the stocking every year of fish and the general erosion of the river…..couple that with very little actual habitat creation by the club and what you will get is year on year a gradual decline in the number of fish caught……which will mean more stocking so the vicious circle will continue!
