Course Synopsis

The aim of this course is to provide sufficient knowledge about all physiological phenomena in fishes. The subject provides information to obtain better growth by following physiological aspects during extensive or semi-intensive culture. It also emphasizes thoroughly in breeding of most culturable freshwater fished by manipulating reproductive and endocrinological aspects during natural season as well as off seasons.
