Multiple certification schemes cover farmed fish welfare, but their standards, verification methods, and scope vary considerably, making consumer choice complex.
Aquaculture certification is a valuable welfare tool when standards are robust and verification is credible. Current schemes vary considerably in the depth of welfare provisions, the rigor of auditing, and the involvement of independent welfare scientists in standard-setting. Consumers seeking to make welfare-positive choices need transparent comparative information about what different certifications actually mean for fish welfare. The gap between better and worse certified products is real and meaningful for animal welfare.
