Don’t feed the Fish!

Important Reasons Why We Don’t Feed The Fish

If you’re doing a boat sightseeing tour around Phuket you may occasionally come across fish feeding. It is done to attract fish to the boat and entertain the tourists but many people aren’t aware that this practice is bad for the fish and the environment alike, and should be avoided to protect our reefs.

There are hundreds of species of fish on our reefs around Phuket which you can see on your diving or snorkeling daytrip, however in some areas such as Coral Island where uneducated tour boat operators sometimes feed the fish, you will see only 1 or 2 species and this is due to the detrimental effects of fish-feeding. Those species can be seen in large numbers which can look impressive but if left to their own devices there would be many more species of fish present in the water, not just 1 or 2.

Here we explain why we don’t feed the fish.

Unnatural Diet

Just like humans, fish need the right type of food in their diets and it is essential that they eat important amino acids, of which they can only receive from their natural diet – not bread, or scraps of food that humans eat. Bread is particularly bad as it contains yeast and when eaten by fish, expands in their digestive system causing health problems. The most resilient fish may survive however others die or fall ill and are taken by predators.

Unnatural Behaiviour

Hand-feeding fish and other marine life promotes a behaviour called conditioning, where the animal learns to associate humans with food instead of being naturally cautious around humans. A fish’s natural diet is quite complicated and may be seasonal, daily, or temporal. When fish start to anticipate meal times with humans, it interferes with their natural feeding cycles and they are more vulnerable to predators. A healthy marine community relies on competition for habitat and food and different species feed during different times of the day. Introducing an unnatural meal disturbs these competitive relationships and can lead to the decline of certain species and over-population of others. In a location where fish are regularly fed there are often feeding frenzies and people present may get injured.

Damage To The Environment

Hand-feeding fish takes a toll on the marine environment too. Adding food to the water around reefs increases nutrient levels which then increases the growth of harmful algae that damage corals. The majority of reef fish are grazers, meaning they only eat algae. They keep the growth of the algae on coral reefs under control so that the reefs aren’t smothered. By feeding fish their behaviour is modified so that they no longer graze on the harmful algae that need to be removed from the reef, the algae may become overgrown. Eventually the reef is destroyed and the habitat of many species is lost.

Be Responsible

We encourage you to be responsible on your sightseeing tour or on your snorkeling or diving trip.
Don’t feed the fish or throw any food scraps overboard, place them in the bin instead.
And if you see someone feeding the fish, please ask them to stop doing it and if you can, explain to them why. Share this information with your friends and family too.
