Fish are an important resource for humans worldwide, especially as food.
Commercial and subsistence fishers hunt fish in wild fisheries (see fishing) or farm them in ponds or in cages in the ocean (see aquaculture).
They are also caught by recreational fishers, kept as pets, raised by fishkeepers, and exhibited in public aquaria.
Fish have had a role in culture through the ages, serving as deities, religious symbols, and as the subjects of art, books and movies. (source)
So can hamsters eat fish?
It is not the best food for hamsters but they can have a little of it.
Do watch out for any bones though as they will lodge in their throats.
