The invention discloses a bionic robotic fish for ocean underwater sampling, and relates to the technical field of underwater sampling, and the bionic robotic fish comprises a fish body, a sampling assembly, a power system located at the fish tail of the fish body, and an observation system located at the fish head; the power system provides lifting and advancing power for the fish body, and the observation system is used for avoiding obstacles; the sampling assembly is embedded in the belly of a fish body and comprises a machine body box, an electric telescopic rod, a fixing plate and the like. The machine box is fixed to the belly of a fish body, electric telescopic rods are symmetrically arranged on the two sides in the machine box, the output ends of the electric telescopic rods are connected with fixing plates, the bottoms of the fixing plates are connected with limiting ring blocks through butt joint frames, and disc bodies are rotationally connected to the limiting ring blocks. Four micro motors are circumferentially fixed in the disc body, and four column casings are correspondingly fixed on the outer section of the disc body; the collecting cylinder is detachably connected with the column casing through threads; the annular frame is fixed outside the column casing and is provided with a filter membrane and an air bag; the filter membrane is used for passive collection, the collecting cylinder is used for active collection, and the air bag expands and contracts to rotate the disc body, so that sampling efficiency is improved.
