Health Management and Disease Control

For vannamei in RAS

Remember: Good management practices reduce stress factors.

Variables to be used in health evaluation:

Survival Rate Mortality Rates Growth Rates

Size Variation Feed Conversion Ratio Shrimp Appearance

Health evaluation tests and procedures:

Wet Mount Procedure Post Larvae visual examination and fitness Stress test for post larva

Gill examination Mid-gut Intestine Fullness Examination Stomach Contents Analysis

Disease control:

Decreasing density, partial or early harvests Drugs, chemicals and treatments Sanitation
