The book has been compiled in ten chapters. Chapter-III to Chapter-VII is sub headed into Introduction, Materials and Methods, Observations and Results and Discussion. Subject index is designed to locate the important terms and name of fish. A separate author index has also been added. The cited references are enlisted under bibliography. The summary of the contents of the book may be pointed as: Chapter-I is planned to discuss introductory aspects of fish transportation. Chapter-II explains brief historical review of the process of fish transportation. Chapter-III begins with the process of determination of aquatic and bimodal oxygen uptake of fishes. The detailed account of oxygen uptake seems to be plinth for fish transportation. Chapter-IV gives an account of oxygen uptake of fishes under association in still water and continuously flowing water conditions. The information is necessary for the calculation of either increase or decrease of oxygen requirement during packing of fishes in a grouped condition. The study helps in determination of optimum number of fishes considered for packing. Chapter-V explains determination of optimum dose of anaesthetics namely Benzocaine and MS-222 of fishes and its effect on the oxygen uptake. The information is helpful for the calculation of decrease of oxygen requirement during packing of fishes. Chapter-VI deals with effect of ammonia on ultra structure of gill under scanning electron microscope and oxygen uptake of fishes. The study is helpful in deciding calculation of complete requirement of oxygen for packing. Chapter-VII critically explains evaluation of suitable packing conditions based on the information from Chapters III to VI under normal situation and present situation of COVID-19. Chapter-VIII reviews a general discussion of entire account of various processes of fish transportation. Chapter-IX describes summary and conclusions observed from the work of fish transportation. Chapter-X deals with a flow sheet, a proposal and a future scope of fish transportation.
