Effect of substituting fishmeal with black soldier fly and mealworm larvae meal on nutrient digestibility, body and mineral composition of
Article in Open veterinary journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Aquaculture is a cornerstone of global food security, offering an essential source of protein and nutrition to an ever-growing human population. Fishmeal is a high-protein feed ingredient typically made from wild fish, which increases the depletion of wild fish. Insects such as black soldier fly (BSF) ( Aim: This study evaluated the impact of substituting fishmeal with BSF and MW larvae meal on the nutrient digestibility and body and mineral composition of Methods: A 60-day feeding trial was conducted using varying levels (0%, 25%, 50%, 75%, and 100%) of BSF and MW diets. Growth performance was assessed using the following parameters: weight gain (WG), feed conversion ratio (FCR), and specific growth rate (SGR). Digestibility trials measured apparent digestibility coefficients for protein, lipid, and gross energy. The proximate and mineral compositions of the fish were also analyzed. Data were subjected to one-way analysis of variance and Tukey's test at Results: The 75% BSF and 50% MW diets exhibited the best growth performance, with significant improvements in WG, FCR, and SGR. Protein digestibility improved significantly, rising from 49.22% (control) to 75.15% in the BSF 75% group and from 50.91% (control) to 75.33% in the MW 50% group. BSF inclusion reduced body fat while increasing protein and ash content, whereas MW showed variable effects on lipid content. Both insect meals enhanced mineral retention, particularly calcium, sodium, phosphorus, and magnesium, with peak values observed in the 75% BSF and 50% MW diets. Conclusion: Replacing fishmeal with BSF and MW larvae meals improves the growth, nutrient digestibility, and mineral composition of
