Processing striped catfish (Pangasianodon hypophthalmus) generates heads–bones, skin, and trimmings that may provide additional revenue, yet their realised economic value at fish-processing units remains insufficiently documented. This study analyses utilisation patterns, commercial volumes, prices, gross sales value, buyer channels, and value concentration among selected processing units. A quantitative descriptive approach was applied to 11 units across seven provinces using 36 processor–product–period records from 2025–2026. Economic valuation was restricted to 16 records with positive volumes, valid prices, and confirmed sales. Five of the 11 units commercialised at least one by-product, three used by-products through non-commercial routes, two reported disposal or zero volume, and one could not be classified. Commercialised volume totalled 32,202.2 kg, generating IDR 235.17 million in gross sales. Heads–bones contributed the largest volume at 18,509.2 kg; however, trimmings generated the highest value at IDR 101.13 million and the highest weighted price at IDR 14,305/kg. Skin generated IDR 67.14 million at IDR 10,137/kg, while heads–bones generated IDR 66.90 million at IDR 3,615/kg. Small and medium enterprises absorbed 74.7% of volume and 76.8% of value. One processing unit accounted for 79.3% of recorded value. The findings demonstrate that catfish by-products have realised economic value, although commercialisation remains narrowly distributed. Market development requires source segregation, quality standards, volume aggregation, and buyer partnerships.
