How were studies carried out to disprove this myth?

At first, it all started with a study that began at the University of Minnesota, because there were many doubts that the lifestyle of the fish was because they had no memory. Therefore, in the research a very curious information emerges, regarding that the fish know different points where to get food at night or where to go when the water is cloudy. After this they can return to the same place where they were before, which means that if they have memory to return.

Fish are able to learn and remember, but they have another memory functioning that is governed by classical conditioning. Classical conditioning is the learning process that is also known as Pavlovian conditioning. It means that two stimuli are needed to perform associative learning. Therefore, two pieces of knowledge will be taken into account.

This is what the University of Minnesota did, based on that it chose two types of music, Blues and Classical. They used the food to achieve results in the fish and could differentiate both, having positive results and proving that the fish work their memory in this way.

How long can a fish’s memory last?

How does your long- and short-term memory work?

In this case, the Technion Institute of Technology of Israel conducted research to know if the memory of the fish was very short or long and to know how long can the memory of the fish last? Helping themselves with the theory already scientifically researched and approved on classical conditioning of their behavior, they relied on sound.

In such a way that in one place they kept a group of fish and fed them every day by playing background music. Then they all released it into the sea so that they lived free in their natural habitat, and 5 months later they placed the same music on the seashore and all the fish came to feed again. From this reason they confirmed again that the classical conditioning of the behavior of fish by sound.

Which fish has the least memory, and which is the one with the most?

It can be said after verifying that fish have the ability to remember, scientists were also responsible for studying the species called Abidochromis Caeruleus better known as African Cichlids.

All this conclusion was because in the sea they have to have enough memory to remember the different points where they get food (because they make different stops).
