To preserve live crabs to keep them fresh, here are some suggestions and steps:
1.Temperature control: The optimal storage temperature for crabs is 0-4 degrees Celsius. To ensure that a constant low temperature is maintained during storage, ice cubes or refrigeration equipment can be used to lower the temperature.
2.Water quality and humidity: Crabs need a moist environment to keep them hydrated. Prepare a container or box and place a layer of moist seaweed or a damp towel at the bottom to provide humidity. Do not allow the water in the container to flood the crabs so that the crabs do not drown.
3.Ventilation: Crabs need plenty of oxygen** to ensure good ventilation in the container. Choose a container with a vent or grid, and make sure the vents aren't too big to prevent the crabs from escaping.
4.Regular inspection and clean-up: Regularly check the health of the crabs inside the storage container and remove any dead crabs from affecting other crabs so that they do not have adverse effects on other crabs.
5.No food intake: Crabs do not need to be eaten during storage, so do not add any food to the container. If crabs have no food intake, their body excretion will decrease, helping to keep the environment clean.
The condition of each crab will vary depending on the freshness of preserving live crabs, but in general, the right preservation method can keep the crabs alive and fresh for a longer period of time. Usually, live crabs can be kept for 1-2 days.
Please note that the above recommendations apply to short-term storage of live crabs, and if you plan to store or transport crabs for a long time, you may need to take more complex methods, such as using professional crab boxes or refrigeration equipment, to ensure the survival and freshness of the crabs.
