Rainbow Trout Aquaculture Diets with Microalgae Substitutes, 84-Day Experiment

Experimental data from an 84-day feeding trial evaluating microalgae as sustainable substitutes for fishmeal and fish oil in juvenile rainbow trout diets. The dataset, published by Pallab Sarker on figshare, includes results from 16 recirculatory aquaculture systems. It likely contains measurements of nutrient digestibility tracked using an indigestible marker.

Use Cases

• Compare growth performance and nutrient utilization based on different levels of fishmeal and fish oil replacement.
• Analyze the digestibility of key nutrients based on the use of the Yttrium oxide marker mentioned in the description.
• Model the environmental impact of feed substitutions based on the described microalgae co-products.
• Assess the feasibility of 100% replacement diets for rainbow trout based on the experimental diet groups NSW100 and NSO100.

Strengths

• Experimental design includes a control and three distinct treatment diets with specific replacement percentages (75% and 100%).
• Feeding trial lasted for a defined period of 84 days.
• Data is published under a permissive CC0-1.0 license, allowing unrestricted use.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small (12.8 KB), indicating limited scope and likely a summary or subset of results.
