Animal Training and Enrichment

Bristol Aquarium is home to around 5,000 animals and each species has its very own specific needs and requirements. From sensitive seahorses to hardy crustaceans it is really important that we adapt their environments to best suit their lifestyles.

Naturally-themed displays

Animals are adapted to cope within a particular environment, whether that is the ever-changing tides on the coastline or a mangrove forest with its vast network of roots and hiding spaces. One way that we ensure our animals are coping with their environment is to provide naturally-themed displays.


Intelligence under the sea is something that is often overlooked however studies have shown that fish are capable of complex behavioural interactions and understanding the world around them.

Our animals are provided with a whole range of enrichment to keep them mentally stimulated. We use a technique called ‘Operant Conditioning’ which means that we gradually build a connection between an object or a cue with the reward of food.


Port Jackson Sharks

We have successfully trained our Port Jackson Sharks to bop their nose against a blue ball for a food reward. This conditioning allows us to individually target-feed them to ensure they are all getting the right quantity of food to follow a healthy diet.



Archer Fish

Archer Fish have an incredible natural ability to shoot jets of water using a special groove in their mouths. They do this in the wild to knock insects and spiders from low hanging branches into the water for a quick meal.

We encourage this natural behaviour by replicating similar conditions in their display. We have created a target above the water’s surface where we put their favourite foods to be knocked off into the water.

Did you know: Archer Fish can account for the refraction of light through the water’s surface and angle their jet perfectly into position!



Pufferfish have the intelligence to associate colours and shapes with different meanings – check out some of the amazing videos of pufferfish training online!

We have successfully trained our pufferfish to swim to a green hula hoop and wait underneath before receiving a food reward. That’s not all… When placing a green and a white hula hoop in the tank at the same time, the pufferfish know to only go to the green one – amazing!



This is just a snapshot of some of the things we do to keep our animals fit and healthy both physically and mentally. Here are Bristol Aquarium we are committed to keeping animal welfare our number one priority.
