Description
Technical Field
The invention belongs to the field of aquaculture, and particularly relates to a fish, shrimp and crab mixed aquaculture pond and a method for aquaculture by using the same.
Background
The portunus trituberculatus is a main variety for seawater pond culture, the culture density cannot be too large due to mutual disability of the portunus trituberculatus, and the portunus trituberculatus is a living characteristic of benthonic, so the water body utilization rate is not high. The common culture mode at present is fish, shrimp and crab mixed culture, the method fully utilizes the culture water body, and the portunus trituberculatus ingests residual feed to purify the water body, thereby realizing the maximization of the culture benefit. However, because hidden objects such as fish reefs and the like are lacked in the culture pond, the density of the portunus trituberculatus seedlings cannot be too high, otherwise mutual killing is caused, and if the hidden objects are thrown, the water body flow is influenced, dead corners are easily formed, and the water body is lack of oxygen.
Disclosure of Invention
The invention aims to solve the technical problem of providing a fish, shrimp and crab mixed culture pond and a method for culturing fish, shrimp and crab by using the same.
The invention is realized by the following technical scheme
A mixed aquaculture pond for fishes, shrimps and crabs is characterized in that the aquaculture pond is a rectangular mud pond, a water inlet and a water outlet are formed in the width edge of the rectangular mud pond and are respectively positioned at the two ends of the width edge, a fish reef is arranged in the center of the aquaculture pond, the length of the whole fish reef is larger than the width of the fish reef, and a symmetry axis in the length direction of the fish reef is overlapped with a symmetry axis in the length direction of the pond; the fish reef is a hollow body formed by enclosing 2 long walls and 2 short walls, the fish reef is axisymmetric, the top and the bottom of the fish reef are both open, the 2 long walls of the fish reef are in a convex arc shape, and a central angle corresponding to the arc is 15-30 degrees; the short wall of the fish reef is provided with through holes.
Furthermore, the holes are densely distributed at the position of 10-20cm of the bottom of the short wall, and the diameter of the holes at the bottom is 5-8 cm; the middle upper part of the short wall is also provided with a through hole with the diameter of more than or equal to 10 cm; furthermore, holes which are communicated with the inside and the outside of the hollow body are distributed at the position of 10-20cm away from the bottom of the long wall, and the diameter of each hole is 5-8 cm; and the joint of the long wall and the short wall is arc-shaped.
Furthermore, the height of the hollow body fish reef is more than or equal to the culture water depth.
Furthermore, the hollow body fish reef occupies 1/2-1/3 of the bottom area of the aquaculture pond.
The method for mixed culture by utilizing the pond comprises the steps of arranging the fish reefs in a rectangular mud pond, putting stones or other small fish reefs in hollow body fish reefs, feeding water through a water inlet, putting crab seedlings in a hollow body, putting shrimp seedlings and fish seedlings in the pond, opening a water outlet to drain water simultaneously in the culture process, pumping out culture water from a water pump to have initial kinetic energy, circularly flowing along the arc-shaped wall of the hollow body fish reefs, draining water through the water outlet, and pumping the discharged culture water into the culture pond again through the water inlet after sedimentation treatment of a sedimentation tank.
Compared with the prior art, the invention has the beneficial effects that:
the fish reef is a hollow body, compared with the existing solid fish reef, the water body utilization space is increased, small pieces of fish reefs are thrown into the structure of the hollow body fish reef, a habitat is provided for crabs cultured in a mixed mode, and the small pieces of fish reefs are located inside the hollow body fish reef, so that resistance cannot be increased to water circulation flow for large pond culture.
The middle upper part of the short wall of the hollow body fish reef is provided with the through hole with the depth of more than 10cm, so that the mixed cultured fishes can freely penetrate into the water body in the hollow body, and meanwhile, the cultured crabs can freely shuttle inside and outside the solid body fish reef due to the through hole with the depth of 5-8cm arranged at the lower part of the wall of the hollow body, so that the cultured water body is increased compared with the traditional solid body fish reef, the mixed culture density of fishes and crabs can be increased, and the water body output is improved.
The wall of the hollow body fish reef is arc-shaped, so that the loss of kinetic energy of circulating flow of water for pond culture is reduced, the water body of the culture pond is always in a flowing state, the dissolved oxygen of the water body is increased, and the corruption of sludge at the bottom of the pond is reduced.
Detailed Description
The technical solution of the present invention is further explained by the following examples, but the scope of the present invention is not limited in any way by the examples.
Example 1
A pond for mixed culture of fishes, shrimps and crabs is a rectangular mud pond and is provided with a cement protection slope, the length of the mud pond is 40m, the width of the mud pond is 30m, the water depth is 1.5m, a water inlet and a water outlet are arranged on the width edge of the rectangular mud pond and are respectively positioned at two ends of the width edge, a fish reef is arranged in the center of the mud pond, the length of the whole fish reef is larger than the width, the height of the fish reef is 1.6m and is positioned on the long central axis of the rectangular mud pond, the fish reef is a hollow body formed by a long wall and a short wall in a surrounding mode, the top and the bottom of the fish reef are both open, the long wall of the fish reef is in a convex arc shape, and the central angle corresponding; the short wall of the fish reef is provided with through holes, the holes are densely distributed at the position 15cm away from the bottom of the short wall, and the diameter of the holes at the bottom is 7 cm; the middle upper part of the short wall is also provided with a through hole with the diameter of 15 cm; holes communicating the inside and the outside of the hollow body are distributed at the position 15cm away from the bottom of the long wall, the diameter of each hole is 7cm, the part above the long wall is not permeable, the consumption of kinetic energy of a water body by the holes on the wall of the hollow body is reduced, and the connecting position of the long wall and the short wall is arc-shaped.
