ISRAEL - Technion researchers have shown that fish can remember stimuli for between four and five months, offering the opportunity for more environment-friendly farming in future.

Previous studies into fish memory led to the conclusion that fish can remember for only three seconds.

However, Israel National News reports that researchers Boaz Tzion, Assaf Barki and Ilan Karplus have presented their new study.

They said the new findings could be used to develop environmentally friendly methods of fish farming based on conditioned reflexes. Farmers could train fish to return to a certain point when called, allowing the use of open areas instead of cages that cause ecological damage.
