High-density terrapin animal breeding device

Abstract

The invention discloses a high-density terrapin animal breeding device. The high-density terrapin animal breeding device comprises a breeding pond; a funnel-shaped excrement residue feed collector is arranged at the bottom of the breeding pond; the funnel opening of the funnel-shaped excrement residue feed collector is connected with a discharge conduit; the bleed hole of the discharge conduit is provided with a water valve; an entire-body clapboard is arranged at the upper port of the funnel-shaped excrement residue feed collector; at least two layers of split clapboards are arranged above the entire-body clapboard; a 18-22cm gap is left between the split clapboards at the same layer; the interval between the layers of each layer of clapboards is in the range of 18-22cm; and multiple even-distributed long leaks with the width of 0.4-0.5cm are arranged on the entire-body clapboard and the split clapboards. The high-density terrapin animal breeding device has the advantages of increasing the breeding density of terrapins and the utilization rate of the breeding space, also improving the quality of water in which the terrapins live, improving the living environment for terrapin breeding, greatly reducing the water changing frequency of terrapin breeding, saving energy sources and reducing the pollution to environments.

Description

technical field [0001] The invention relates to a breeding device for animals, in particular to a high-density breeding device for turtles. Background technique [0002] In recent years, the aquaculture industry has developed rapidly. Soft-shelled turtles are widely favored by people due to their high nutritional and medicinal value. Greenhouse soft-shelled turtle farming is a high-density farming model characterized by high input of artificial bait. In this intensive and high-density culture, the amount of residual bait and excrement exceeds the natural decomposition ability of microorganisms in the culture pond. Since the soft-shelled turtle is a benthic reptile, its behavior of frequent crawling and breathing on the water surface, The excrement feces and residual bait settled at the bottom of the pond are brought into the waters where the soft-shelled turtles live, and dissolved in the water, making the ammonia nitrogen (NH 4 + -N) and chemical oxygen demand (COD) conc...

Problems solved by technology

In this intensive and high-density culture, the amount of residual bait and excrement exceeds the natural decomposition ability of microorganisms in the culture pond. Since the soft-shelled turtle is a benthic reptile, its behavior of frequent crawling and breathing on the water surface, The feces and residual bait settled at the bottom of the pond are brought into the waters where the soft-shelled turtles live, and dissolved in the water, making the ammonia nitrogen (NH 4 + -N) and chemical oxygen demand (COD) concentrations up to 100mg·L -1 and 300mg·L -1 The above results in deterioration of water quality, which directly affects the healthy breeding of soft-shelled turtles, and the resulting frequent water changes not only consume energy, but also damage the ecological environment.
