Fish Stress: Causes & How to Control It 🐟
Stress is one of the biggest silent killers in fish farming. Stressed fish eat less, grow slowly and become vulnerable to disease.
Common causes of stress in fish:
❌ Poor water quality
❌ Low dissolved oxygen
❌ Overcrowding
❌ Rough handling during harvesting or transfer
❌ Sudden changes in temperature or water level
❌ Overfeeding or poor-quality feed
❌ Disease and parasites
✅ How to reduce and overcome fish stress:
✔ Maintain good water quality and regular water exchange
✔ Avoid overcrowding ponds or tanks
✔ Handle fish gently and only when necessary
✔ Feed high-quality feed at the right time
✔ Monitor oxygen levels, especially early morning and at night
✔ Observe fish daily for early signs of stress or disease
