Sorry Oberlee...While I am highly respectful of everyone's 2 cents, since we're on the subject of awareness, I wanted to share some info with you about studies that have shown that fish do indeed feel pain.
Following is just one of many links you can find if you google, "fish feel pain."
Fish 'capable of experiencing pain' - 30 April 2003 - New Scientist
Our world tends to have a hierarchal view of the animal kingdom with humans self-placed, of course, at the top. I think the only way this puffed-up exaggerated sense of self importance is ever going to change is if aliens land on the planet. Humans will very quickly move down a 'notch' in the hierarchy in an instantaneous rude awakening. Only by that sobering experience will we truly know what we have done to other creatures for so long.
For our current discussion, as we move down the 'hierarchy,' through the purportedly 'less important' species....like rats, mice, insects and...yes...fish, there is a very sad desensitization that takes place...I've actually heard people say, that eating chicken isn't as 'bad' (morally) as eating beef and eating fish isn't as bad as eating chicken.
Speciesism at its worst. But that's a whole other 'google.'
