Are you a fan of mild-flavored and versatile fish? Then you might have tried or heard about Swai fish and Tilapia. Both are popular choices in the seafood world and can be found in many grocery stores and restaurants.
Swai fish is a type of freshwater fish that is native to Southeast Asia, specifically the Mekong River basin.
It belongs to the same group as catfish and is also known as iridescent shark, basa fish, and tra fish. The scientific name of Swai fish is Pangasianodon hypophthalmus and it typically grows up to 4 feet in length.
Swai fish is an omnivorous fish that feeds on crustaceans, small fish, and plants. It is typically found in freshwater habitats such as rivers, lakes, and ponds.
The fish is primarily found in Southeast Asia, specifically in countries such as Vietnam, Thailand, and Cambodia, and is a major export to the United States.
The fish has been controversial in the United States due to concerns about its farming practices and labeling. In the past, it was marketed as “Asian catfish,” but US laws no longer permit this name to be used.
Tilapia
Tilapia is a type of freshwater fish that is native to Africa, but can now be found in many parts of the world, including the United States.
It is a member of the cichlid family and there are nearly 100 species of Tilapia. The scientific name for Tilapia varies depending on the species, but some common ones include Oreochromis niloticus and Tilapia rendalli.
Tilapia are typically omnivorous fish that feed on plants, algae, and small aquatic animals. They are known for their mild flavor and are a popular choice for many people due to their affordability.
