Summary

Moderate dietary biochar improved gut measures and cut nitrogen pollutants without changing bass growth.

In a 42-day trial, 480 largemouth bass received feed containing zero, 10, 20, or 40 grams of mulberry-branch biochar per kilogram. Moderate levels increased digestive enzymes and microbial richness and reduced ammonia nitrogen by 60.7 percent in the 10-gram group and 49.3 percent in the 20-gram group by day 42. Growth did not change significantly, and the highest dose may disturb microbial balance; commercial aquaculture effects remain to be tested.

Why it matters

Moderate dietary biochar improved gut measures and cut nitrogen pollutants without changing bass growth.

Limits and context

  • Growth did not change significantly, and the highest dose may disturb microbial balance; commercial aquaculture effects remain to be tested.

Key claims

  1. Moderate dietary biochar improved gut measures and cut nitrogen pollutants without changing bass growth.
