Understanding Nitrogen Cycling in Fish Hatcheries: Causes of Mortality

This article explores the critical role of nitrogen cycling—encompassing ammonia, nitrite, and nitrate—in fish hatcheries. It examines the leading causes of mortality over time, focusing on two major factors: improper food supply and hazardous physical environments. Understanding these elements is essential for improving fish health and hatchery success. By addressing issues in nitrogen management and environmental conditions, hatchery operators can significantly reduce mortality rates and enhance fish production efficiency.
