Provided are a power generation apparatus and an aquarium equipment. The power generation apparatus includes a water pump (1) and a magnetic induction generator (2). The water pump (1) includes a housing (100), a stator (11) mounted in the housing (100), a first rotor assembly (12), and an impeller (13) connected to the first rotor assembly (12). The first rotor assembly (12) includes a first permanent magnet rotor (121) and a first rotating shaft (122) disposed at an axis of the first permanent magnet rotor (121). The first permanent magnet rotor (121) is disposed adjacent to the stator (11). The magnetic induction generator (2) is disposed adjacent to the stator (11) or to the first permanent magnet rotor (121) and is operative to be coupled to an electric device. The stator (11) includes a coil winding (112) operative to be coupled to an external power source, so that when the coil winding (112) is coupled to an input alternating current, the first permanent magnet rotor (121) rotates enabling the magnetic induction generator (2) to generate an induced current to power up the electric device. The aquarium equipment includes the power generation apparatus described above.
