 :::: Another statement of evidence of no concensus is the following from The American Fisheries Society in their guidelines for use of fish in research:  http://fisheries.org/guide-for-the-use-of-fishes-in-research#4.3 , section 4.3, Nociception and Pain, end of first paragraph "Overall, the weight of evidence in the fish species studied indicates that the experience of pain in mammals is not experienced in fish".  This contrasts with statements to the contrary which are often made by other groups, such that I think we can safely say there is currently no consensus on the topic. Hence I would like to reiterate that the first section should have this paragraph inserted  
 "However, other scientists point out there are several neurobiological features in teleost fish and elasmobranchs that suggest they are unlikely to be capable of pain perception in a manner similar to mammals or humans. Because of this, there is currently no scientific consensus on the topic, which remains controversial."      00:41, 30
