A lot of the data assumes growth and survival as your main measures of welfare/​stress which is just doing the industry’s yield optimisation research for them rather than welfare research. It is analogous to setting up a chicken welfare institute that tries to make bigger and longer-living chickens. A proxy of welfare, in a way, but we don’t need welfare research orgs to do this work.
The other concrete data in those papers are things like: the demonstrated preference of BSF maggots for honey over sugar water, data on the optimal grinding method to kill BSF maggots most quickly, and data on optimal densities to normalise breeding behaviours. The part that is betrayed by confidence intervals is the implementation. Without any way to define or measure the value of maggot suffering with any confidence, there’s no way to know whether the costs of implementing any of these changes are justified. At least with vertebrates we have some intuitions about how much their suffering matters to fall back on.
