The memory of fish can lasts for days, not seconds

African Cichlid fish have a memory span of up to twelve days, a new study has shown. Researchers trained the fish to go to one end of a tank for food before they then rested them for 12 days. When the fish were returned to the tank they spent more time in the area they associated with being fed, suggesting they remembered their training. 

 

The result of the study adds further evidence of the complex mental abilities of fish. Findings are being presented at the Society for Experimental Biology's annual meeting. African cichlids, Labidochromis caeruleus, are a popular fish for aquarium owners. The scientists from MacEwan University, Canada, decided to study them because they are reported to be intelligent fish, showing complex behaviour such as aggression. Lead scientist, Dr Trevor Hamilton, said: "There are many anecdotes about how smart these fish are. Some people even believe that their cichlids watch television with them."

Brain of all vertebrates are quite complex and perhaps all, including brain from fish, have a potential for quite advanced mental functions. It seems that some species devolved such potential more than others- would be great to find out

I agree, fish that remember where food is located would have an evolutionary advantage over those that do not Reply

There is an enormous investment in neuroscience and understanding complex functions such as "memory". It is now possible not only to better understand a way that the brain makes memories, but also how to create new memories with specific content

Yes, it has been reported that neurobiologists created new, specific memories by direct manipulation of the brain - this could prove key to understanding learning and memory disorders Reply

It is hard to see another in pain like that. And still allow them their space and dignity. I wonder if she saw your concern as clearly and you saw her disserst? Reply
