Effects of Different Carbon Sources on the Growth and Production of Rotifer (Brachionus plicatilis) in a Zero‐Water Exchange Biofloc Culture System

Aquaculture Research, Volume 2024, Issue 1, 2024.
Brachionus plicatilis is considered an indispensable first live feed for many fish and crustacean larvae; the demand for the species has increased globally. The mass production of the rotifer involves quality microalga and a standard diet; this culture is expensive and needs a skilled workforce.
