Fish's memories last for months, say scientists

While it was previously believed that a fish's memory span was only three seconds, scientists now believe they can remember for up to five months. Fish trained to remember a certain sound while in captivity remembered and reacted to the same sound after months in the wild. The research could help promote more natural, and less costly, fish farming techniques.
Scientists at the Israeli Technion Institute of Technology in Haifa spent a month schooling young fish to associate a certain sound with feeding time.
