Abstract: Embodiments of this application provide a path planning method and apparatus, and a vehicle. The method includes: obtaining a first area in which a surmountable obstacle around a vehicle is located; and planning a traveling path based on the first area, where the traveling path includes a first location, the first location is a location at which a tire is located when the vehicle performs a gear shift operation, and the first location is outside the first area. Embodiments of this application may be applied to an intelligent vehicle or an electric vehicle, to help improve continuity and comfort of intelligent driving assistance, and help improve driving experience of a user.

Abstract: A device for high density culture of fish larvae includes: a nursery tank, a first aerotube, a standing mesh drain pipe, and a dual-drain recirculating water treatment system. The nursery tank is a rounded corner tank or a polygonal tank without dead corners. The first aerotube is disposed around the bottom of the inner wall of the nursery tank. The standing mesh drain pipe is disposed in the center of the bottom of the nursery tank. The dual-drain recirculating water treatment system includes a first water treatment system and a second water treatment system. The first water treatment system and the second water treatment system are symmetrically disposed on both sides of the nursery tank, respectively. The first water treatment system is configured to purify upper layer water of the nursery tank, and the second water treatment system is configured to purify lower layer water of the nursery tank.

Abstract: A device for fish reproduction, hatching and larval culture including an aeration device, a first netted division plate, a second netted division plate, a first water pump, a first net cage, a second water pump, and a second net cage. When in use, the device is disposed in a pond. The pond includes a breeding area, a hatching area, and a nursery area, and each of the breeding area, the hatching area, and the nursery area communicates with the other two. The first netted division plate is disposed between the breeding area and the hatching area, and a first water recirculating loop is formed between the breeding area and the hatching area to drive water to flow from the breeding area to the hatching area, and back to the breeding area. The second netted division plate is disposed between the hatching area and the nursery area.
