Compared with terrestrial pond turtles, cage turtles have the advantages of simple facilities, management and labor saving, no need to change water, no occupation of cultivated land, no investment, quick start-up, easy migration, etc., and are suitable for farming in broad areas such as rivers, lakes and rivers. The economic benefits are significant. It is also suitable for the internal network enclosure of large artificial fish ponds to increase the unit output rate of fish ponds and increase the income.
China is rich in water resources, and it should use cages in idle water to raise turtles scientifically.
Cage turtles have different structures and setting methods because of different water areas and different turtle species. Localities should be determined flexibly according to actual conditions. In particular, the cage materials are nylon, polypropylene, and metal, which can be determined based on economic strength. The arrangement of cages should be based on the ecological conditions and environmental conditions of the water bodies that can be used for rational distribution, such as leaving waterways, docks and other necessary water space, but also to avoid pollution of water sources. Cage turtles are better for young, medium and adult turtles. Parents' turtles are not easily set up spawning grounds in the net and are generally not used.
Net cage production:
The turtle cage can be selected according to the size of the turtle body mesh mesh different, made of rectangular or square, the general size of 20 square meters -100 square meters, network depth 2m as well. In order to prevent the turtle from escaping from the net surface, a net cover should be added around the net surface to form the “T†character of the land pool. Since turtles are not afraid of lack of oxygen, hatchlings can be kept to a minimum of 5 square meters.
Cage settings:
In the water area where the cage is placed, a bamboo stake or a concrete pillar is erected around the net according to the size of the net. The net is fixed and the net is immersed in the water at a depth of 0.4m-0.8m. The net is fixed at four corners and around the sinker. Prevent water or wind from tilting the net. The feed table is located at the center point of the four sides. Commonly used wood boards are made into 1m*2m ring gears, and nylon screens are nailed in the middle to prevent feed sinking or being blown away by wind and waves to reduce feed wastage.
Stocking density:
Turtle is mild, does not kill, and does not require high dissolved oxygen in the water. Net cages in large water areas will not be deprived of oxygen due to the replacement of water flow and the promotion of wind waves. Therefore, the number of units stocked can be raised by 2 times than that of ordinary land pools. - 5 times, 1 square meter cage can raise 120 turtles, 60 turtles -80, and 20 turtles -40.
Feeding:
The most suitable feed for cage turtles is buoyant granular material, which is put into the feed table and floats on the surface of the water, allowing turtles to ingest food freely. The use of powder materials to mix in and discharge water into groups is acceptable, but the bottom of the bait should be covered with fine mesh nylon yarn. Prevent feed loss. Generally about 1500 grams of material per 50kg turtle daily, in principle, feeding the feed within 2 hours is better.
Pest control:
Very few turtles get sick. In order to prevent pathogenic bacteria from infecting the waters, the water in the cage can be disinfected periodically. 20 g of bleaching powder is used per cubic meter of water. When raising young turtles, it is advisable to prevent water rat and leeches from harming. It is advisable to use metal nets. Other management work is the same as conventional turtles.
The most important feature of cages for raising turtles is high yield, which can produce more than 10kg per square meter per year, and it has no effect on the original cultured species such as fish in the water.
