Description
In this book the authors have discuss the results of detailed studies on the nature of the food, its qualitative and quantitative estimations, seasonal variations and correlations in twenty-four species of some common freshwater fishes of Northern India. On the basis of the nature of ingested food, the fishes studied by the authors have been broadly divided into three primary groups - the herbivores, the omnivores and the carnivores. On the basis of the feeding affinities to particular water levels wherein their specific food items abound, the fishes under report have been classified into three secondary groups : the surface feeders, the mid feeders and the bottom feeders. Such a classification has been applied to Indian freshwater fishes for the first time. The structures in the buccopharynx of the twenty-four species studied, the types of teeth and their disposition, the gill rakers, and the alimentary tract are all briefly described and discussed and relationships between form and function established conclusively for the first time in India.
