About The Book

The present book entitled “The Problems in Aquaculture and its Solutions” is a need based document and can solve the queries in the mind of students, teachers, researchers and the farming community in general. This is the outcome of cumulative years of my experience with the fish/shrimp farming community of West Bengal, Odisha, Bihar, Chattishgarh, Assam, Tripura, Jharkhand and Haryana etc. Aquaculture is a problematic science and needs to be addressed in line with the local condition. The book comprises of 32 different chapters of multiple areas , which needs proper knowledge for its solutions. The different chapters of varying arena are nothing but the associated problems of fish/shrimp culture. The last chapter is very much interesting and these are the number of queries of a enthusiastic minds and the ready answers for it. Many chapters are enriched with illustrated photographs for better understanding. The graphs and the statistical datas/ information are updated and have been used at appropriate places. I tried to emphasize much on various problems and also the solutions for it. While solving various issues in Aquaculture in the farmer's field I come across with these type of associated problems and that has prompted me to go for preparing this manuscript. It took good number of years for me to accumulate all these ideas and place it in one arranged format and proceed for publication. My practical experience with farming sector has inspired and taught me to go for documenting these contents for future generations. I hope this will be a ready reference for the Students, Researchers, Teachers , Officers of the concerned Departments, Policy makers and the Farmers in general.
