Calanus Finmarchicus Hydrolysate Effects on Whiteleg Shrimp Growth and Stress Resilience

A 62-day feeding trial assessed five experimental diets for whiteleg shrimp, including a novel hydrolysate from the copepod Calanus finmarchicus. The study, authored by Isak Bøgwald and shared on figshare, measured growth performance, feed utilization, and responses to an acute salinity challenge. Shrimp fed the hydrolysate showed improved feed efficiency, nutrient retention, and the highest survival rate under salinity stress.

Use Cases

• Evaluating fishmeal replacement strategies in shrimp diets based on the described experimental design
• Modeling the relationship between feed composition and stress resilience based on immune and metabolic markers
• Comparing the efficacy of marine-derived protein sources like krill meal, squid-liver meal, and hydrolysates

Strengths

• The dataset includes results from a 62-day controlled feeding trial with standardized diets
• Experimental design compares four marine ingredients against a control and a tuna hydrolysate benchmark
• Outcomes measured include growth, feed efficiency, whole-body composition, and stress response metrics

Limitations

• The primary data file is a DOCX document (831.7 KB), suggesting the underlying raw data tables may not be directly machine-readable
• Column-level documentation is absent; field semantics must be inferred from the manuscript text
• Row count is unknown, which may limit suitability assessment for direct analysis
