[Delphinus]

Two points -

1. How does one know by looking at a fish if it's captive-raised versus just some small fish that happened to be caught in a net (or by other means)? Just because it's species "X"? No offense, but ...... How can we quantify our confidence in the claim/assertion?

2. In James' example it sounds as if there might be "more effort" put into the process of producing that smaller fish into the store. A specific facility was set up, the larvae was presumably fed with food and stuff, and so on. How does that effort get funded or subsidized? Aren't we basically saying, that the small fish has value added? Thus, if a fish is 1/5th the size of another at the store, is it fair to assume that the smaller fish should be exactly 1/5th the retail price of the larger? I may have been over exaggerating my example on the two fish sizes with respect to the shipping (it should have been obvious that it was a completely arbitrary example not based or grounded in reality), but my intent was not to explain the shipping process in detail, but rather to try to illustrate that there are other variables besides just size at play, when determining a retail "value" of an animal. I do believe that size plays a pivotal role, but I believe that other variables do as well.
