He argues that a parallel trade in premium wild tiger products is bound to emerge once farmed tiger items hit the market, and that there is little incentive for tiger breeders to report inventory discrepancies, to help screen out wild tiger products or enforce the ban against their use.
We also compared Hg concentrations in farmed seafood items relative to concentrations in their wild seafood counterparts.
Both wild and farmed seafood items can have low minimum mean Hg concentrations [e.g., 0.005 and 0.008 for wild and farmed catfish, respectively; see Supplemental Material, Table S1 (http://dx.doi.org/10.1289/ehp.1205122)].
For some seafood categories, the species composition of farmed and wild items was not identical.
Why is farmed salmon a particular risk?
The interrogations comprised 36 separate hybridisations; 3 states (wild × wild; farmed × wild, farmed × farmed) × 2 time-points (sac fry and fed fry) × 6 biological replicates.

In contrast, our study found consistently lower mean Hg concentrations in farmed seafood across studies for multiple seafood items.
Serum samples were also collected from farmed rabbits on 4 farms in Spain.
