Evaluating the nutritional and economic potential of defatted algae cake in aquaculture: A review.
Review in Animal nutrition (Zhongguo xu mu shou yi xue hui), 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
The increasing demand for sustainable aquafeed ingredients has driven the exploration of alternative protein sources to replace conventional fishmeal and soybean meal. Defatted algae cake (DAC), a by-product of microalgae-based biofuel production, presents a promising and eco-friendly protein source for aquaculture. This review examines the potential of DAC as a sustainable alternative feed ingredient by assessing its nutritional composition, inclusion levels, digestibility, economic feasibility, and environmental benefits. Rich in proteins, essential amino acids, bioactive compounds, and functional lipids, DAC has demonstrated positive effects on fish growth, feed efficiency, and immune responses when incorporated at optimal levels. However, high production cost, variability in nutrient composition, the presence of anti-nutritional factors, and species-specific dietary requirements pose challenges to its widespread application. Comparative analyses indicate that DAC inclusion levels at optimal levels, generally under 10% in fish feed, can maintain growth performance across various species, while higher levels may impact digestibility, feed efficiency, and nutrient bioavailability. The economic viability of DAC is influenced by its cost relative to traditional feed ingredients, advancements in processing, improved digestibility for fish, and integration within circular bioeconomy models. Additionally, its use in aquaculture contributes to sustainability by reducing reliance on overexploited marine resources and mitigating environmental impacts associated with fishmeal and soybean meal production. This review highlights the need for further optimization in DAC processing and formulation to enhance its utilization as a cost-effective and sustainable aquafeed ingredient, supporting the long-term growth of the aquaculture industry.
