Transgenic improvement: Salmon, trout technology awaits regulatory approval
Transgenic salmon and trout developed by AquaBounty Technologies are minimally different from other farm-raised fish, but exhibit impressive and inheritable growth rates.
Responsibility
Flawed risk assessment of contaminants in salmon
A risk assessment of PCBs and other contaminants in farmed and wild salmon was flawed and did not reflect public health community opinions.
Intelligence
Fat content, freezing affect cold-smoked salmon quality
Product quality in cold-smoked salmon is best maintained by smoking fresh fish with high fat content and freezing them after, not before, smoking.
