Study Notes
Fish Health Management
- A disease in the context of fish health management is a harmful deviation from the normal functioning of physiological processes, usually associated with specific signs and symptoms.
Snieszko's Diagram
- The blackened triangular area in Snieszko's diagram signifies the interaction between the environment, host, and pathogen, which leads to disease development.
Components of Fish Health Management
- The main components involved in fish health management include the environment, host, and pathogen, which interact with each other to cause disease.
Diagnostic Laboratory
- The purpose of sending samples to a diagnostic laboratory in fish health management is to identify the causative agent of disease, determine its pathogenicity, and develop an effective control strategy.
Levels of Diagnosis
- The level of diagnosis that involves virology, electron microscopy, immunology, and molecular diagnostics is the advanced or confirmatory level of diagnosis, which provides a definitive diagnosis of the disease.
Host-Related Factors
- Some factors related to the host in fish health management include age, size, nutritional status, and genetic resistance, which can affect the susceptibility of fish to disease.
