How to raise small sand crabs, and can sand crabs be raised in fresh water?

1. Breeding environment: When breeding small sand crabs, a glass tank filled with sand should be used as a utensil, and salt water should be poured into it. 2. Feeding management

Provide feed for the small sand crabs once a day, and place the food on the surface of the sand soil so that the small sand crabs can feed themselves. 3. Precautions: Provide scattered light for small sand crabs, and keep the depth of the fish tank above 15 cm.

1. Breeding environment

When raising small sand crabs, fish tanks or FRP should be used as breeding utensils, spread sand with a depth of 30 cm, and pile them into a slope shape, and then pour salt water with a concentration of salt water into the tank, so that the water surface can reach two-thirds of the slope.

2. Feeding management

In the process of breeding small sand crabs, you can provide feed once a day, put the food on the sand on the water surface, let the small sand crabs eat by themselves, the food is mainly fish, shellfish, shrimp and algae, and during the breeding period, it is necessary to regularly match spirulina and harvest shrimp shelling eggs.

3. Precautions

Small sand crabs like sunlight, in the process of breeding, half of the glass tank can be placed in the sun, the other half is shaded with a sunshade net to provide scattered light, and in order to avoid the small sand crab escaping during the breeding period, the depth of the glass tank should be adjusted to more than 15 cm to avoid the phenomenon of escape.

If it's a freshwater sand crab, it's fine.

Sand crabs. It can eat animal foods such as flies, insects, and decaying small animal carcasses, as well as algae.

and other plant foods, and when raising sand crabs, you need to lay one to two centimeters of fine sand at the bottom of the fish tank, and then put in the sand crabs, and add water to cover the body of the sand crabs, pay attention to add salt to the water, in order to simulate the seawater environment, and promote the sand crabs to quickly adapt to the environment.

Sand crabs can eat animal foods such as flies, insects, and decaying small animal carcasses, as well as plant foods such as algae, because sand crabs have a very mixed diet, and are a dominant crab in the intertidal zone of the warm sea, often living on the beach, and sand crabs are agile.

Before raising sand crabs, you need to prepare a fish tank or storage box of the right size as a breeding container, and spread a layer of one to two centimeters of fine sand at the bottom, and then put in the sand crab, and add water to cover the body of the sand crab, pay attention to add a small amount of salt to the water, in order to simulate the seawater environment.

In the process of raising sand crabs, one-third of the water should be changed every week in summer, and it can be changed every two weeks in winter, and fed with minced fish, algae and other foods once a day, and pay attention to the uneaten food needs to be cleaned up in time, so as not to make the water turbid, which is not conducive to the growth and development of sand crabs.

When maintaining sand crabs, you can choose semi-open-air breeding methods, so that sand crabs can get full sunlight, which is conducive to its growth and development, so as to promote the growth and growth of sand crabs.

Sand crab breeding method:

1. Place: Prepare a large water basin for raising sand crabs, put about one-fifth of the volume of fine sand, and form a steep slope that simulates a beach;

2. Add water: put the sand crab into the basin, pour water about the back of the sand crab, and add a little edible salt to the water to achieve sterilization and disinfection;

3. Food: Feed red worms, egg yolks, chicken and duck offal, small fish and shrimp, etc. It is also necessary to feed some grass food;

4. Sunlight: Sand crabs need an appropriate amount of sunlight every day;

5. External environment deficiency: The feeding intensity of sand crabs increases or decreases with the change of season and water temperature. In summer and autumn, when the water temperature rises above 15 degrees Celsius, the feeding ability of sand crabs is enhanced, and they need to be fed once a day. When the water temperature drops below 15 degrees Celsius, the feeding ability of the sand crab decreases, and it can be fed every other day or several days.

Since crabs are diurnal aquatic animals, the feeding time is mainly around the evening.

6. Habits: Sand crabs are social animals, and multiple sand crabs are raised at the same time to achieve a high survival rate;

7. Cleaning: Regularly clean pots, sand, crab shells, etc. to prevent bacterial breeding. The number of water changes is about once every 2 to 4 days;
