Improved growth, body composition, and fatty acid composition in striped catfish juveniles, Pangasianodon hypophthalmus, fed with diets containing different oil sources

Striped catfish are one of the main aquaculture species in Asia. However, the low level of omega‐3 fatty acids in its body makes this species less attractive compared with marine fish. This study aimed to investigate the effect of different oils on growth performance, body composition, and fatty acids in striped catfish juveniles. A basal diet (T0) was formulated to contain no oil, while four other diets (T1, T2, T3, and T4) were supplemented at 4% with different oils, including salmon oil (SALO), soybean oil (SBO), linseed oil (LSO), and rapeseed oil (RSO). Catfish juveniles with initial body weight (23–24 g/fish) were randomly stocked in 500‐L fiberglass tanks, divided into five treatments, three replicates for each, and fed the experimental diets for 60 days. Results from this study revealed that fish fed the LSO‐supplemented diet had significantly (p
