Abalone can only live in salt water, but not in fresh water. As long as they come into contact with fresh water, they will die because of water absorption and foaming. Even if abalone is cultured in seafood shops for a short time, it is necessary to create a seawater environment for it.
Because abalone lives in the sea in nature, the salinity is generally required to be stable at 29 ~ 365,438+0, with a minimum of 27 and a maximum of 35.
Different kinds of abalone have different breeding temperatures. Generally, abalone can't withstand high temperature, and the breeding temperature is required to be below 20 degrees Celsius. The suitable water temperature for the growth of Haliotis diversicolor is 23-30℃, the lowest tolerance temperature is 8℃, the highest is 32℃, and the best water temperature is 28℃.
Preservation method of abalone
1, ice water cooling and preservation: put fresh abalone in ice water to cool down, let it be dormant, and then put it in a food-grade ice bag incubator.
2, salt water preservation: put the abalone into the basin, add the right amount of water to drown half of the abalone, then add a small amount of salt and put it in the shade. If it is winter, put it on the balcony; If it is summer, put it in the refrigerator.
3. Plastic wrap tin foil preservation: seal the fresh abalone with plastic wrap, then seal it with a layer of tin foil, and finally put it in a fresh-keeping box and put it in a freezer.
4. Soak in oil to keep fresh: soak abalone in oil, then put it in a fresh-keeping bag or box separately, and then put it in the refrigerator for cold storage (store it separately to avoid odor).
