Optimizing dietary protein and lipid levels for better growth performance, nutrient retention and flesh quality of grow-out striped catfish (Pangasianodon hypophthalmus).

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This study evaluated the effects of dietary protein (DP) and lipid (DL) levels on the growth, nutrient retention, and flesh quality of striped catfish (Pangasianodon hypophthalmus). A 3 × 3 factorial design was used with three protein levels (28%, 30%, 32%) and three lipid levels (4%, 6%, 8%). Nine experimental diets were fed to fish (initial weight 167.91 ± 0.03 g) for 8 weeks. Results showed significant (p < 0.05) effects of DP and DL on growth performance and flesh quality. The DP28/DL4 diet yielded better growth, feed conversion ratio (FCR), and specific growth rate (SGR) while reducing intraperitoneal fat index (IPFI) and oxidative stress markers. Whole-body chemical analysis indicated higher protein retention (16.65 ± 0.04%) and lower lipid deposition (5.39 ± 0.07%) in the DP28/DL4 group. Flesh quality assessments revealed higher water-holding capacity (WHC), pH, and sensory attributes in DP28/DL4-fed fish. In contrast, higher lipid levels (6-8%) led to increased fat accumulation and oxidative instability. These findings highlight the importance of optimizing DP and DL levels for better growth, nutrient efficiency, and fish quality, supporting sustainable aquaculture and improved production efficiency.
