Jones IS good about not having unwanted fish in their mix. But the "All fish are raised in their own specific ponds" may or may not be 100% true. If you consider buying fish, putting them in your pond, feeding them for a length of time (short or long) "raising fish", then the statement is correct.
Next time you talk to them, bring up the "all fish are raised in their own specific ponds" and ask them if all the fish that they sell are hatched and raised from eggs in their ponds. If they say no, then you could ask for clarification on their "all fish are raised in their own specific ponds" statement. If the guy says yes, that is interesting because they buy fish from some of the same suppliers that I do.
It may mean that they don't mix species in their ponds, which is how they are supposed to be raised.
