Climate of Pakistan is arid and semiarid with unusual and uneven rainfall. Abundant land is affected with salinity and water-logging and the sub soil or underground water become brackish/ saline. These places can be utilized for fish culture which will act as a tool for desalinization of the soil through brackish water fish farming. Due to the influence of climate change circumstances, intrusion of sea water into coastal inland areas rapidly and freshwater scarcity because of less precipitation, agriculture lands are disturbed and didn¿t give profit. Major carps also under stress in saline waters didn¿t give better yield. It is serious issue to utilize that land for fish farming instead of agriculture and to verify a source of less priced and excellent protein quality (animal origin) in future. Salinity of water is an environmental element which effect on growing efficiency of many fish species cultured in ponds, tanks, raceways, and net cages. The present study reports to investigate suitable range of salinity for desire growth, feed utilization, meat quality and survival ratio of Common carp in controlled conditions.

This book discusses the natural and anthropogenic determinants of the environment and their impact on human health. It throws light on the perspectives of climate change with case studies from Australia, India, Italy, and Latin America. Themes covered are ecology of antibiotic resistant microorganisms, pesticide and heavy metal (arsenic) problems in natural environment; molecular advances in understanding of microbial interactions; ecological studies of human/animal health and diseases; food security, technological developments and more. The various chapters incorporate both theoretical and applied aspects and may serve as baseline information for future research through which significant development is possible.
