Can ducks eat canned fish?

Yes ducks can eat canned fish.

Whether fresh or canned, fish is good for them.

Depending on the fish used, fresh fish can have the same nutritional value as the canned or have less.

For example, the fresh tuna has more nutritional value than its canned counterpart.

Canned tuna can be packed in oil or water.

Canned tuna packed in oil contains more protein which is good for your ducks.

However canned tuna packed in water is better for everyday use as it contains less fat than the ones packed in oil.

You don’t want your ducks to get too fat. Canned fish is also high in sodium but low in mercury.

So how much is too much?

Tuna should not be used as your ducks’ main diet.

It cannot provide them all the required nutrients necessary for their growth and health.

A serving once in a week or two is enough.

Tuna contains mercury which can be very dangerous to ducks if consumed too much.

Canned tuna also contains sodium which can lead to impacted crops or obesity.

It is advisable to wash canned tuna first, before offering it to your ducks.

That way, you can be sure of the ingredients used in preparing it and know they won’t be harmful to your pets.

Since your ducks would be eating it and not you, you can skip salt.

It isn’t necessary.

It can even be harmful to them.

Add other nutritious treats like veggies and tomatoes to make it better and more enjoyable for your ducks.


Tuna is a saltwater fish and I can tell you for free that ducks love eating fish.

They can be seen in the pond foraging and eating fish in their leisure time.

Tuna provides them protein, vitamins and minerals that are very beneficial to their health.

With tuna, ducks lay more quality eggs, grow faster and the risks of some diseases are reduced.

Tuna should however not be overfed to ducks.
