The Present Book Applied Fishery Science Is The Outcome Of The Intensive Efforts Made By The Author For More Than Five Consecutive Years To Bring The Universally Spread Documented Informations And Data, Both Traditional As Well As Research Oriented Recent Findings, Before The Scientific World In A Consolidated Form, Specially Before Those Who Are Concerned With Fish Farming And For Capture Of Fishes From Varied Water Sources. Several Valuable Informations Have Been Provided On The Fish Farming Requisites, Such As Methods Of The Quality Fish Seed Procurement, Their Safe Transportation, Design And Layout For The Construction Of New Ponds, Maintenance Of Required Water Quality In The Ponds, Availability Of Choiced Food Items At Proper Times, Use Of Right Kinds Of Fertilizers And Provision Of Supplementary Feeds At Emerging Times. Infrastructural Details And Operation Methods Of Fishing Gears And Some Informations On Related Accessaries, Particularly Trawlers, Fishing Boats And Vessels And Several Kinds Of Crafts, Traps And Angling Implements To Catch Sporting Fishes Have Been Given With Lucid Illustrations.

Trade And Commerce Prospects With The Inclusion Of Accounts Of Fish Processing, Fish Preservation, Various Kinds Of Fish By-Products And Scope Of Marketing Of Fish Have Been Made Highly Explicit.A Fine Attempt Has Been Made To Provide As Many As Fifty One Aspects Of Applied Fishery Science, Merging Together In One Book In Order To Meet The Requirements Of Sylabi Of Universities, Technical/Professional Institutions, Advanced Centres Of Fisheries Education And Research. It Is Hoped That The Academicians, Researchers/Fishery Scientists, Graduate And Post-Graduate Students Of Fishery Science Will Cherish The Author S Endeavour In Finding Appreciable Utility Of The Book.
