Tiger shovelnose is also commonly kept in aquairum, known as Tigrinis.
***TSN are the 8-9 described catfish species in the genus Pseudoplatystoma. Tigrinus is a common name for Brachyplatystoma tigrinum, that used to be called Merodontis tigrinus, hence the name stuck. It's a fish from a genus different from TSN.
But there are different species or strains of Tigrinis.
***Now Brachyplatystoma genus has also about half a dozen species.
I never know that there are indigenous shovelnose species in Lima as shovelnose is an Amazon species. Lima is located in the Pacific side of the Andes.
***I don't know the origin of the specifier "lima" in the name of the catfish Sorubim lima, but regardless of that, a name doesn't always imply where the fish is from. Sorubim is a genus of catfish collectively referred to as just shovelnose or common shovelnose, and lima shovelnose or LSN is mostly sold in the hobby, although we suspect most of them are actually Sorubim elongatus, but this is beyond the scope of current discussion.
I never know you can buy shovelnose fillet in US. What name does it come under and where can you buy them.
***I didn't know either. Trent surprised me but the fact that it is an ethnic food, it seems, makes sense. No widespread availability / popularity.
The most common catfish fillet in US is Mekong giant catfish imported from SE Asia under the name Swai. It's good tasting white meat with flaky texture similar to Doncella.
***Do correct me if I am wrong, but I've read that swai is the iridescent shark catfish meat, Pangasianodon hypophthalmus, not gigas aka MGC or Mekong Giant Catfish. It says so on some packages of swai too. People appear to struggle to ward off complete extinction of the MGC both in the wild and in farming operations. Hardly would MGC be available as a food fish. It may be. I am just thinking aloud. Or its hybrid is.
