Provided are a power generation apparatus and an aquarium equipment. The power generation apparatus includes a water pump and a magnetic induction generator. The water pump includes a housing, a stator mounted in the housing, a first rotor assembly, and an impeller connected to the first rotor assembly. The first rotor assembly includes a first permanent magnet rotor and a first rotating shaft disposed at an axis of the first permanent magnet rotor. The first permanent magnet rotor is disposed adjacent to the stator. The magnetic induction generator is disposed adjacent to the stator or to the first permanent magnet rotor and is operative to be coupled to an electric device. The stator includes a coil winding operative to be coupled to an external power source, so that when the coil winding is coupled to an input alternating current, the first permanent magnet rotor rotates enabling the magnetic induction generator to generate an induced current to power up the electric device. The aquarium equipment includes the power generation apparatus described above.
