Preface
Human population growth has placed a significant demand on fish as a food source placing it is a significant source of protein for millions of people in the world. It is estimated that approximately 25 per cent of all protein consumed by people comes from fish. For some developing nations fish provides a large percentage of protein for its own people as well as a source of income as an export product.
Fish research has become an increasingly important study as fish populations decline throughout the world. The decline of fish has an immense impact on ocean eco-systems as well as a significant impact on one of the primary food sources for people around the world. Overfishing in the past 50 years has significantly reduced fish populations across a large number of species. Research in ichthyology helps policymakers determine what course of action to take in order to maintain fish populations throughout the world. National and international policies are determined based on the data provided by fish research.
India is known for fishing and has seen rapid advances in this sector. Indian central government initiated a dedicated organization focused on fisheries, under its Ministry of Agriculture. Fish production rose from 800.000 tons in 1950 to 4.1 million tons in the early 1990S and through 2010, Indian fish industry growth has accelerated, reaching a total marine and freshwater fish production to about 8 million metric tons.
An International Conference on Recent Trends in Climate Change Researches vis-a-vis Biodiversity was organized at MJP Rohilkhand University, Bareilly during 3rd to 4th December, 2012 under the auspices of “Center of Excellence”, Government of Uttar Pradesh and the Indian Academy of Environmental Sciences, Hardwar. This is the third volume of the publication of the Proceeding, the first (Modern Parasitology) and the second (Environment and Biodiversity) volumes have already been published.
We place on record our appreciation to all the contributors of this volume for their unabated co-operation extended at every step which has made it possible to publish this piece of work.
