"The waters would be faster flowing, deeper, and ideal locations for farming salmon," he says.
Farming salmon: an example of aquaculture for the mass market.
Figure 1 shows a range of effects, from a large negative effect for swordfish and shark to modest positive effects for trout, farmed salmon, and herring.
As a result, risk-based consumption advice for farmed salmon is more stringent than consumption advice for wild salmon (Hites et al. 2004a).
But there are less destructive ways to farm salmon.
This paper presents the results from a choice experiment which examines whether the Irish public is willing to pay a premium for "sustainably produced" farmed salmon from an IMTA process.
Linoleic acid (C18 2n6) were at 67, 647, 604, and 1719 mg/100 g muscles for wild salmon, farmed salmon, supermarket salmon, and salmon feed [ 16]; which were higher than most of the samples (4.3 215.3 mg/100 g wet sample) in current study (Table 4).
(The same dish was offered with organic Icelandic farmed salmon for $26).
Estimated omega-3 FA benefits outweigh MeHg risks for some species (e.g., farmed salmon, herring, trout); however, the opposite was true for others (swordfish, shark).
The one thing farmed salmon has going for it is that the fish are, as Roberts says, "efficient feed converters": salmon require only a little more than a pound of feed for every pound of weight that they gain.
The farmed salmon juveniles used for the present study originated from the Norwegian Mowi strain maintained by Marine Harvest at Tveitevåg, Norway.
