The document discusses fish health management in aquaculture, emphasizing the importance of preventive measures over treatment to maintain healthy fish and prevent disease outbreaks. Key factors affecting fish health include water quality, nutrition, and proper management practices. It also highlights the common symptoms of diseases, the complexity of disease outbreaks, and available resources for managing these issues.

3.  Fish health management is a term used in aquaculture to
describe management practices which are designed to
prevent fish disease. Once fish get sick it can be difficult to
salvage them.
Successful fish health management begins with prevention
of disease rather than treatment. Prevention of fish disease is
accomplished through good water quality
management, nutrition and sanitation. Without this
foundation it is impossible to prevent outbreaks of
opportunistic diseases.
 The first point to appreciate is that not all diseases are
infectious. For example, some are caused by toxins, others
by nutritional imbalances.
 Infectious disease outbreaks in ponds depend on particular
interactions between the host, the pathogen and the pond
environment
Introduction

4. Fish Health Management GOALS
Production of healthy, high
quality fish
Prevent introduction of disease to
healthy animals
Prevent propagation of existing
disease agents

5. • Maintain
conditions
which are
designed to
optimize
growth, feed
conversion,
reproduction
and survival.
2
• Intensive
aquaculture
high numbers,
close
quarters, lots
of food!!
(optimal?)
3
• Enhance natural
resistance
• Well managed
fish have healthy
immune systems!
• Healthy fish give
rise to healthier
offspring!
Principles of fish health management

6. Factors affecting fish health

7.  Unusual movements
 Abnormal and unhealthy look
 Discoloration
 Film like covering on the skin
 Swelling or spots on the skin
 Pale gills, white and red spot on gills
 Excess slime secretion
 Increasing the internal resistance
of fish is important in the prevention
of diseases.
 Selection of healthy fish seeds.
 Proper density and rational culture.
 Proper pond management
 Qualitatively uniform ratio and
quality food
 Good water quality
 Prevention of fish body from
injury

Manipulating the disease triangle

9.  Fish disease outbreaks are often complex, involving both infectious and non-
infectious processes.
 Appropriate therapy often involves medication and changes in husbandry
practices. Assistance from UF/IFAS aquaculture extension specialists is available
to help you to manage disease outbreaks and develop management programs to
prevent them.
 A list of public laboratories available to assist with diagnoses of fish disease is
provided for your convenience at the end of this publication.
 There are many private veterinarians willing to see fish or aquaculture species
in their practice.
