Raising river crabs at home requires attention to multiple aspects to ensure their healthy growth. Here are some key breeding steps and precautions: 1. Prepare suitable containers
Container selection: Choose a larger plastic bucket, glass tank, or aquarium as a habitat for river crabs. The size of the container should be determined based on the number of river crabs, and it is generally recommended that each crab requires at least 5 liters of space to avoid overcrowding.
Container layout: Lay a layer of clean sand or small stones at the bottom of the container, with a thickness of about 3-5 centimeters, to simulate the natural environment and provide a place for hiding and movement. At the same time, some stones, tiles, or tree branches can be placed as a cover for the river crab. You can also plant some aquatic plants, such as aquatic plants, to beautify the environment and provide oxygen and food. 2、 Provide suitable water quality
Water source selection: River crabs require high water quality, and it is best to use pollution-free river water, lake water, or well water for aquaculture. If these water sources are not available, tap water can be used, but it is necessary to air dry for 2-3 days in advance to remove chlorine gas and other harmful substances.
Water quality management: Regularly replace the water, usually once a week, with 1/3-1/2 of the water volume replaced each time. When replacing water, pay attention to changes in water temperature and try to maintain a stable water temperature. Filters or oxygen pumps can be used to maintain clean water quality and sufficient oxygen. 3、 Provide sufficient food
Food selection: River crabs are omnivorous animals that can eat aquatic plants, algae, small fish, shrimp, snails, earthworms, and other foods. When raising at home, you can choose easily accessible foods such as vegetable leaves, fruit peels, rice, breadcrumbs, fish, shrimp, etc.
Feeding method: Evenly sprinkle the food on the water surface or sand in the container, allowing the river crab to search for and eat on its own. Pay attention to controlling the feeding amount and avoid excessive intake that may cause water pollution. Generally, it is recommended to feed the river crab once a day, with the appropriate amount to be consumed within 1-2 hours. 4、 Pay attention to the breeding environment
Avoid direct sunlight: River crabs prefer dark and humid environments, so containers should be placed in well ventilated areas away from direct sunlight.
Preventing escape: River crabs have strong climbing ability and are easy to escape. Cover the container with a layer of gauze or mesh to prevent river crabs from escaping. The aperture of the gauze or mesh should be smaller than the body size of the river crab.
Avoid interference: Try to minimize interference with river crabs and avoid frequently moving containers or touching them. When observing the behavior and health status of river crabs, it is important to maintain silence. 5、 Other precautions
Regular inspection: Regularly check the health status of river crabs and the water quality, food, and other conditions inside the container, promptly identify problems and take measures.
Disease prevention and control: Pay attention to the prevention and control of diseases in river crabs. If abnormal behavior or disease symptoms are found, timely measures should be taken for treatment. During the breeding process, the principle of prevention before disease and prioritizing prevention should be followed.
Choosing suitable containers, providing appropriate water quality and food, paying attention to the breeding environment, and conducting regular inspections and management are necessary for raising river crabs at home. As long as these aspects of work are done seriously, river crabs can grow healthily at home.
