Behavioral and Climate Change on Fish Nematology

Mamatha P and Ramachandra Mohan M

Abstract The impact of fish nematode on gill histopathologyl and damages are predominate in their filaments, primary lamellae, degeneration of epithelium, inter lamellar epithelium and clumping of RBCs. Results of present study on fish, Glossogobius giuris indicates that there was parasites in gill, Further studies are made to understand in terms of metacercariae in fish tissues like gill of naturally available and highly proteinaceous fish, in Cauvery delta region. Fish gills are continuously exposed to water for gaseous exchange, during this there was a possible contact of Trematode parasites. The major any favorable conditions to enhance the incidence of Trematoda parasites and water chemistry like pH, DO, BOD and COD along with the temperature have any role for abundance of fish parasites. Variations in temperature with 3-4°C are seems to be favorable for behavioral and climate change on fish nematology.
