Snakehead fish is a native fish in Sumatra, Java, and Kalimantan but is an introduced fish in Sulawesi and Papua. Channa striata, or snakehead fish, is a freshwater fish that has many health benefits, especially its albumin content for wound healing. Other types of freshwater fish that are suspected of having potential for albumin, besides snakehead fish, are toman fish (Channa micropeltes) and betutu fish (Oxyeotris marmorata). Snakehead fish are also very suitable for treating stunting that occurs in children.
