Problems solved by technology

However, the living habits of soft-shelled turtle are different from that of Chinese soft-shelled turtle. They live on the sandy bottom all year round and do not like to sunbathe their backs. They only stick their heads out of the water to exhale when they take a breath. The disease is not easy to observe, it is difficult to take early prevention and treatment, and the overall survival rate of breeding is low

Embodiment 1

[0036] The indoor circulating water cultivation system of the soft-shelled turtle seed of this embodiment is as figure 1 As shown, it includes the seedling cultivation device 1 at the low position, the water purification device 2 at the high position and the water circulation pipe 3 connecting the seedling cultivation device 1 and the water purification device 2, wherein:

[0037] The seedling cultivation device 1 comprises a seedling cultivation pool 11 and a central pipe 12, a water layer 111 and a sand layer 112 are provided in the seedling cultivation pond 11, the central pipe 12 is erected at the central position of the seedling cultivation pond 11, and the pipe wall of the central pipe 12 is provided with There is an isolation net area 121. The isolation net area 121 is set higher than the sand layer 112 and submerged in the water layer 111 to filter the pool water entering the central pipe 12. In addition, the central pipe 12 is vertically provided with drainage Pipe 13...

Embodiment 2

[0042] A kind of indoor circulating water cultivation method of soft-shelled turtle seedlings, comprising the steps of:

[0043] (1) Add sand layer and water layer in the seedling pond, open the booster pump, and start water circulation;

[0044] (2) Water cycle for one day and put the soft-shelled turtle seedlings after the water in the seedling pond is clear;

[0045] (3) Feed bait in the seedling pond for conventional feeding. The bait added is live bait. The live bait of the first-year-old turtle is dace fry or mosquito fish with a body length of less than 2 cm; the live bait of the second-year-old turtle Dace fry or mosquito fish with body length less than 4cm;

[0046] (4) Clean the sand settling area formed at the bottom of the central pipe every 2 months, and open the valve of the sewage pipe once a month for 30 seconds each time; Wash once every 2 months;

[0047] (5) Add a certain amount of clean water to the seedling pond in real time to keep the water level unch...

Abstract

The invention provides an indoor circulating water cultivation system for pelochelys bibroni fry. The system comprises a fry cultivation device, a water cleaning device and a water circulating pipe, wherein the fry cultivation device comprises a fry cultivation pool and a center pipe; a water layer and a sand layer are arranged in the fry cultivation; the center pipe is vertical in the fry cultivation pool; a separation net area is arranged on the wall of the center pipe; in addition, a drain pipe is vertically arranged in the center pipe; the water cleaning device comprises a water cleaning barrel and a separation pipe; the separation pipe is arranged in the water cleaning barrel in a hanging manner; a filtering layer is arranged between the water cleaning barrel and the separation pipe; a blow-off pipe is arranged at the lower part of the water cleaning barrel; a bottom blow-off structure is arranged above a blow-off inlet of the blow-off pipe; the water circulating pipe comprises a sewage outlet pipe and a clean water feeding pipe which are respectively used for discharging sewage in the fry cultivation pool and supplementing filtered sewage into the fry cultivation pool. In addition, the invention provides an indoor circulating water cultivation method for the pelochelys bibroni fry. The water used in the system is circulating filtrating water, the quality of water is ensured, the cultivation survival rate of the pelochelys bibroni is high, and the cultivation management and scientific research observation are facilitated.

Description

technical field [0001] The invention relates to the technical field of animal artificial breeding, in particular to an indoor circulating water cultivation system and method suitable for 2-year-old and younger P. Background technique [0002] Tortoise (Pelochelys cantorii, 1864) belongs to Chordate Phylum, Reptilia, Turtle Order, Turtle Branch, and Genus. The carapace of an adult individual is as long as 1m, which is one of the largest individuals of the turtle family. In 1989, the turtle was listed as a first-class aquatic wildlife protection animal in China. It was compared with giant pandas and baiji dolphins, and it was called "aquatic giant pandas". Mature soft-shelled turtles are large in weight and late in sexual maturity. The continuous deterioration of their habitats and the random hunting of humans have led to a gradual reduction in their distribution area and population. They are already critically endangered and extinct in some areas. It was also listed as an e...
