Can eels be raised at home in clear water?
Generally not recommended. First of all, the eel is not breathing with the gills, it is relying on the oral cavity and the laryngeal cavity of the inner wall of the epidermis as a respiratory auxiliary organs, by the surface of the larynx microvascular direct absorption of oxygen. Therefore, when eels leave the water, unlike other fish that breathe with gills, their life time will be shortened, and then the environment in which eels live is silt, not water, so it is easier to raise eels with water at home and death will occur. Therefore, it is best not to use water to raise eels for a long time, if you eat immediately, you can use water to raise to help spit mud and sand.
Can eels be raised in a fish tank for a long time?
Yes, but it is not good to keep. Eels like to live in the cave, is a night foraging omnivorous fish, mainly animal feed-based, if you will buy back the eel, placed in the home aquarium, simulating the eel's silt environment, can be used to raise eels for a long time, but the eel on the feed requirements of the residence of the high, do not consume decaying animal feed, so it will be more trouble to raise, and generally will not be willing to, and for a long time, eels may also appear! Death, so it is recommended to buy fresh eel is better, its nutrition and taste are better.
How long does it take for an eel to die?
Generally more than 12 hours is not recommended to eat again. The shape of the eel is more like a snake, generally living in ponds, rivers and rice paddies inside the mud hole, so generally carry a lot of bacteria and parasites, and the eel after the death of these bacteria and parasites will increase over time, and secondly, the eel is a kind of high-protein food, after the death of the time is too long will lead to the deterioration of its proteins, and thus transformed into a toxic amine, after eating is not healthy, so the eel is a kind of high-protein food, after the death of the time is too long will lead to the deterioration of its proteins, and thus become toxic amine, after consuming, not healthy. Therefore, it is generally recommended that eels should not be consumed 12 hours after death.
Can I eat the eels after they are frozen?
You can eat it. In general, after the death of eels, at room temperature will quickly decompose a large number of bacteria and other harmful substances, thus leading to the deterioration of eels, eels in the refrigerator frozen to keep, can be very good inhibition of eel bacteria and parasites breeding, thus to a certain extent to extend the shelf life of the eels, so the eels killed in the refrigerator after the freezer can continue to eat, just do not store too long, generally recommended to put 1-2 days or so! It's a good idea to keep it in the refrigerator for about 1-2 days.
