SEA LIFE London Aquarium - School Children and Diver

Looking after a large population of sharks is thirsty work!

The most important things we monitor when caring for our sharks are their feeding schedule, lighting and water conditions, and checking for signs of illness.

The water in the shark tank needs to contain just the right amount of salt, and we also closely monitor the levels of ammonia, nitrates and nitrites in the water. We test the water regularly to ensure that the tanks filters are working properly and that all the fish waste is taken out.

The lighting levels in the tank mimic levels of light seen in nature, so the lighting is dimmed at night to simulate night time. Nurse Sharks are nocturnal, so they become more active at night.

We record all feeds to keep a record of what our sharks are eating and when. Our sharks only get fed three times a week. This may not sound like much to us but in the wild they don’t even eat that often! Most of our sharks eat lots of different fish including Mackerel and Pollock.

We also carefully monitor our sharks for any signs of illness – this can most frequently be seen if a shark stops feeding, isolates itself, or changes their swimming behaviour. All sharks have behaviours that are normal to them, so we keep a close eye to check that nothing is changing.
