Swai - Pangasuis hypophthalmus
Have you had a crispy fried fish or tangy sauced fish at a local restaurant or pub lately?
If you answered yes, you probably have already tasted Swai. Swai was originally presented to the foodservice and restaurant industry as a versatile substitute for more expensive white fish. Today it is more appreciated for its mild, sweet taste, year round availability, firm texture and ability to hold up to extended cooking and reheating. Despite its popularity in the foodservice industry, Swai is still relatively unknown to the average consumer.
Swai is farm raised in the rivers of Vietnam and Cambodia and suffers from a bit of an identity crisis. Swai was initially introduced to the market in the early 2000’s as Vietnamese Greysole, Catfish or even Grouper. Sometimes this misidentification came from an attempt to introduce the fish in a context that customers could understand. Other times, unscrupulous importers sold it as Grouper to make a profit from the perception of higher value. Earlier this year, two executives from a Florida-based distribution company were sent to prison for knowingly mislabeling Swai as Grouper. There was also a plea bargain on a similar case in Massachusetts as well.
Adding to the confusion, Swai has gone through a number of name changes. Initially it was identified as Catfish which is an accurate description since it comes from the Catfish family. However, U.S. processors petitioned that labeling it Catfish was misleading. Just a few years ago it was also commonly called Basa bocourti. It was later determined that it was not this specie, but a similar one called Pangasuis hypophthalmus. Currently the FDA allows Pangasuis hypophthalmus to be called Swai, Tra, Striped Pangasuis or Sutchi.
All this confusion about the correct name might be the main reason why many consumers do not know about Swai. One thing for sure is that they have probably already tasted it. It is a very versatile fish, ideal for almost any style of cooking and adaptable to most recipes. Recently, the Monterey Bay Aquarium Seafood WATCH rated farmed Swai as having good potential for being a sustainable species. As seafood prices continue to soar, expect to see Swai, a healthy and versatile fish, become a mainstay on menus and in retail seafood cases and for consumers to start knowing much more about it.
