1. Can eels be kept alive without seawater?Eels are snake-like and scaleless, and are usually found in the sea area where freshwater meets saltwater. Eels are both freshwater and marine fish. Eels lay eggs and reproduce in the deep sea, and grow in freshwater environments. Some types of eels 1. Japanese eel Japanese eels, also known as wind eels, white eels, and green eels, spawn near the Mariana Islands in the western Pacific Ocean. They are mainly distributed in Vietnam, the Philippines, Taiwan, mainland China, the Korean Peninsula, and the Japanese archipelago (except some areas in the north). 2. Eel The perch eel, also known as the flower eel, black ear eel, red earth dragon, and earth dragon, is a migratory fish that goes to sea to spawn. It is widely distributed in streams and rivers in the Indo-Pacific region. 3. Australian eel Australian eel, also known as short-finned eel, commonly known as black eel, is a type of catadromous migratory fish, originally from the sea, which swims upstream to fresh water to grow up, and then returns to the sea to lay eggs. Every spring, large numbers of young eels (also known as white eels and eel lines) enter the river estuaries from the sea in groups. In addition, common eels include European eel, American eel, African eel, New Zealand eel, Indonesian eel and Philippine eel. Eels are divided into seawater eels and freshwater eels. If it is an eel in seawater, you must use seawater to breed it. Generally, freshwater eels grow at the junction of seawater and freshwater! Eels are divided into conger eels and freshwater eels. If it is a freshwater eel, there is no problem. Eels can survive without seawater 2. Recently, there have been cases of sick eels in mud ponds, with redness in the mouths of fish and sporadic deaths of eels and bighead carp, but the cause of the disease cannot be found.To improve the water quality of the pond, you can use the method of hanging ammonium carbonate bags, and drag and drop them according to the degree of turbidity of the pond water. Generally, 12 to 15 kg of ammonium carbonate is used per acre of water surface. First, put the ammonium carbonate into 3-4 small bags made of thin cloth. Tie them to bamboo poles or dry wooden sticks, and then put them into the fish pond, so that the ammonium carbonate bags are hung in the water and slowly dissolve. After the ammonium carbonate is dissolved, the turbid pond water will become clear in about 5 days. It can also increase the fertility of the pond water and floating organisms. It promotes the rapid growth of pond fish and increases production. I hope my answer can help you, thank you for accepting it!! 3.
