Unless the normal Tay salmon is richer in the quality of its flesh 

 than are the fish from the Dee and the Spey, or some considerable 

 variation exists from year to year, this result rather points to the bull- 

 trout of the Tay being over-fed instead of under-fed, as has been 

 supposed, and shows further that the pigment of the salmon's flesh is 

 not an essential accompaniment of the accumulation of fat. At the 

 same time, this high state of nourishment may explain the fact that 

 when hooked the Bull Trout of the Tay offers a remarkably good fight 

 with the angler.
