This word that keeps getting used over and over: handling
If we are trying to use it in an effective scientific debate, it is never ever defined or quantified in any capacity in the article that was quoted
on page 15- It is under the category "procedural stressors", which, I would guess in this context of a fish hatchery (or the aquarium trade), more often refers to capturing and holding a fish in order to move it or to do something like treat it.
Nothing is mentioned about contact of any kind being inherently harmful. Surely the aquatic life in "hands on" exhibits are not subjected to unreasonable stress.
That's the other word: stress
Stress is a part of nature. In large amounts it can cause harm, but in smaller amounts it can be a stimulant, like exercise. What would happen to us if our immune systems weren't constantly exercised by the stress of lesser infections? A cold could be deadly. If you grow tall plants indoors where the air is still, and then take them outside, they can be blown over by a slight breeze. Too much stress is bad, right? Well, what about too little?
Is it also not unreasonable to believe that these puffers are comfortable in using their own very effective natural defenses? -and that in most cases they use it pre-emptively and as a show to avoid being attacked? I don't think it falls into the category also mentioned in the article: Alarm reaction ("fight or flight" response).
Does anyone know if puffers have natural predators in the wild that eat them? If an animal has no natural predators, they become fearless, kind of like the deer that live among the residential neighborhoods around here.
