Plasticity in growth of farmed and wild Atlantic salmon: is the increased growth rate of farmed salmon caused by evolutionary adaptations to the commercial diet?

Table 5 Relative weight differences between farmed, wild and hybrid Atlantic salmon within each diet treatment

Treatment	Group	Weight (g)	Relative difference
Treatment	Group	Weight (g)	to Wild	to Hybrid
Control	Farm	29.70	1.9	1.2
	Hybrid	23.95	1.5	-
	Wild	15.55	-	-
Carp	Farm	10.14	2.1	1.5
	Hybrid	6.87	1.4	-
	Wild	4.80	-	-
Natural	Farm	4.71	1.6	1.2
	Hybrid	3.89	1.3	-
	Wild	2.93	-	-

The relative growth differences were calculated by dividing the average weight (in grams) of the farmed fish by the wild and hybrid fish respectively, and the average weight of the hybrid fish by the wild fish within each treatment
