5 Common Fish Myths and Facts You Need to Know

While some fishing legends are exaggerations, there’s a lot of truth in many of them. Here are the most common fishing myths, debunked for your convenience!


The truth is that the ‘big bait’ trick is pretty useless. The best way to attract fish is to present them with something they recognize, using their favorite foods or lures. The best bait for any location will vary depending on the prevalence in the local area.


Another fishing myth is the belief that rain will stop fish biting. Again this isn’t true – in fact, it can have the opposite effect because fish are susceptible to movements in the water as currents carry it. Disturbing this can cause them to panic and go into feeding mode.


Those who catch-and-release believe that there’s more chance of them coming back and biting again because they let the fish go. This is not true, and there’s no scientific evidence to support it. Of course, if you’re looking for a longer fishing session, the fish may come back on another day, but this isn’t any different from what would happen if you’d caught and kept.


This common fishing myth suggests fish will bite better when the wind is from the east. In fact, this is true for just one reason – the water is moving towards shore, bringing with it food that fish can smell.


The truth is that fish have excellent memories and can remember things for a long time. Goldfish are very intelligent compared to other animals. Scientists have found that they can recognize their owners and even signal when they want food by performing tricks.

What Fish Has the Worst Memory?

There isn’t a single fish that has a bad memory. Some fish have a slightly shorter memory than others, but all fish have good memories.

Goldfish are one of the top members on the list. They can remember up to six months compared to other fish who only remember two weeks.

Do Fish Recognize They Are in a Tank?

Giant fish like sailfish and marlin often swim through an aquarium without realizing they’re in a tank.

Small herbivorous or omnivorous species hardly notice their surroundings.

Still, predatory ones such as bettas and gouramis will show signs of awareness, for example, by swimming back onto the opposite side of its territory from where it came if food has been thrown into this area during feeding time.
