Host-Parasite Interactions in Some Fish Species

Abstract EN

Host-parasite interactions are complex, compounded by factors that are capable of shifting the balance in either direction.

The host's age, behaviour, immunological status, and environmental change can affect the association that is beneficial to the host whereas evasion of the host’s immune response favours the parasite.

In fish, some infections that induce mortality are age and temperature dependent.

Environmental change, especially habitat degradation by anthropogenic pollutants and oceanographic alterations induced by climatic, can influence parasitic-host interaction.

The outcome of these associations will hinge on susceptibility and resistance.
