Fisheries Science as an applied science, is based on the basic principles of several disciplines of arts, science & commerce. This multi-disciplinary science rests on the principles of a wide spectrum of subjects for its success. Therefore, all fish lovers, those who desire to have a career/ livelihood/ business option in fisheries are required to refer literatures of many disciplines; since books containing all the aspects of fisheries; are hardy available in any single compilation. Even though, the book contains the basics of the entire field of fisheries, it is still like a drop in to the vast ocean of a developing science, where new findings are added to every day, through continuous R&D. Therefore, the present work always provides rooms, for further scope of refinements of the contents incorporated. Critical comments; constructive suggestions, for further refinement of the present endeavour, are always welcomed, which will be acknowledged with all humility gratitude. Unintentional mistakes/ omissions, if any, in the present compilation are deeply regretted.
