Fish may actually feel pain and react to it much like humans http://apocadocs.com/s.pl?1241180374
Because both groups of fish wriggled at about the same temperature, the researchers thought the responses might be more like a reflex than a cognitive reaction to experiencing pain.... Upon later observation in their home tanks, however, the researchers noticed that the fish from each group were exhibiting different behaviors.
"The fish given the morphine acted like they always had: swimming and being fish," Garner said. "The fish that had gotten saline -- even though they responded the same in the test -- later acted different, though. They acted with defensive behaviors, indicating wariness, or fear and anxiety."
Nordgreen said those behavioral differences showed that fish can feel both reflexive and cognitive pain.

Next you'll be telling me we should treat fish humanely. Something's fishy about that.
