Problems solved by technology

My research shows that: when the dissolved oxygen content in the turtle pond is above 4mg / L, and the beneficial bacteria in the water body are above 80%, the soft-shelled turtle not only grows rapidly, but also has no disease or injury; if the dissolved oxygen is below 4mg / L, even the beneficial bacteria When the ratio of bacteria is as high as 90%, or the dissolved oxygen is above 4mg / L, but the ratio of beneficial bacteria is below 80%, poor growth and endangered diseases of soft-shelled turtles still occur

Embodiment 1

[0014] Embodiment 1: (1), selection and transformation of aquaculture ponds: select a pond with an area of ​​50 mu, upgrade the pond to a depth of 1.8 meters, and build soft-shelled turtles to rest, bask in the back and bait platform in the pond, and set up soft-shelled turtle anti-escape facilities around the pond ;In the breeding pond, set up DN15 inflatable pipes 3cm away from the bottom of the pond, lay one every 2m, and open a small hole with a diameter of 0.1mm every 0.5m on each pipe. Air leak;

[0015] (2) Breeding quantity: the stocking quantity is 800 juvenile soft-shelled turtles of 40-100g each, 600 small soft-shelled turtles of 100-300g each in the pond per mu of pond; 500 3-5 age clams;

[0016] (3) During the peak season of breeding from May to September, 1 kg of beneficial bacteria per mu is injected every 7 days to keep the number of beneficial bacteria accounting for more than 85% of the total number of bacteria; and, use inflatable equipment to increase oxy...

Embodiment 2

[0019] Embodiment 2: (1), selection and transformation of breeding ponds: select a pond with an area of ​​100 mu, upgrade the pond to a depth of 2.5 meters, and build soft-shelled turtles in the pond to rest, bask in the back and bait platform, and set up soft-shelled turtle prevention facilities around the pond ;In the breeding pond, set up DN40 inflatable pipes 10cm from the bottom of the pond, lay one every 8m, and open a small hole with a diameter of 0.8mm every 1.0m on each pipe. Air leak;

[0020] (2) Aquaculture quantity: stocking quantity is 1,200 juvenile soft-shelled turtles of 40-100g each, 800 small soft-shelled turtles of 100-300g each in the pond per mu of pond; 900 1-2-year-old mussels of pearl mussels are suspended, 700 3-5 age mussels;

[0021] (3) During the peak season of breeding from May to September, 3kg of beneficial bacteria per mu is injected every 15 days to keep the number of beneficial bacteria accounting for more than 80% of the total number of ba...

Abstract

A mixed breeding method of pearl mussels and soft-shelled turtles, including the selection and transformation of the breeding pond, the control of the breeding quantity, the control of the number of beneficial bacteria and oxygen in the breeding water, and the control of the matching breeding quantity of other fish, so that the whole breeding The ecology is at its best. Advantages of the present invention: the present invention effectively utilizes the leftover bait of soft-shelled turtles and the excrement of soft-shelled turtles, and pearl oysters play the role of removing pollution from soft-shelled turtle culture in the breeding process, which is not only beneficial to the growth of soft-shelled turtles, but also satisfies the food demand of soft-shelled turtles, reducing The waste of bait organisms is reduced, the water environment is protected, and the total benefit of breeding is increased by more than 30%.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a mixed culture method of pearl mussels and soft-shelled turtles. Background technique [0002] Soft-shelled turtle, scientific name Chinese soft-shelled turtle ( Amyda Sincnsis ), commonly known as soft-shelled turtles, turtles, etc., are oviparous amphibians and reptiles. Soft-shelled turtle is delicious and has high nutritional value. Because it has many nourishing and medicinal effects, it can clear away heat and nourish yin, calm the liver and relieve wind, soften and harden stagnation, and has curative effects on liver cirrhosis, hepatosplenomegaly, and convulsions in children. Therefore, it is not only a delicacy on the dining table, a high-quality material for a first-class banquet, but also an important traditional Chinese medicine material. The current breeding volume is large. Since freshwater pearl culture was reintroduced from Japan in the early 1960s, it has ...
