Untrimmed Pangasius fillets offer certain advantages for those who prefer to have the complete fish experience in their cooking. The skin can add an extra layer of flavor and moisture to the fillet when cooked, while the bones can enhance the overall taste and texture. Additionally, the presence of some fat can contribute to a richer flavor profile.

When using untrimmed Pangasius fillets, it's important to take the necessary precautions and proper handling procedures. The fillets may require scaling, descaling, or deboning depending on the recipe and personal preference. Careful attention should be given to ensure proper food safety and cleanliness during the preparation and cooking process.

It's worth noting that most Pangasius fillets available in the market are typically sold trimmed, where the skin, bones, and excess fat have been removed. Trimmed fillets are more commonly preferred for convenience and ease of preparation.
