Aknowledgment

At first, all my admiration goes to the supreme creator and Ruler of the universe, the Almighty Allah for His great mercy to keep me alive and enables me to pursue my education in Fisheries and Marine Resource Technology Discipline as well as to complete my work for the degree of Bachelor of Science in Fisheries. I would like to express my sincere gratitude and profound appreciation to my honourable supervisor, Shikder Saiful Islam, Assistant Professor, Fisheries and Marine Resource Technology Discipline, for his continuous guidance, valuable suggestions, critical observations and sustained support in writing this thesis. I would like to express my profound gratitude to Professor Dr. Ghausiatur Reza Banu, Head, Fisheries and Marine Resource Technology Discipline, Khulna University for her valuable suggestions and providence of all necessary facilities. I recall with warm appreciation and great indebtedness or the support, guidance and suggestions extended to me by all of my respected teachers in Fisheries and Marine Resource Technology Discipline, Khulna University. I would also like to give special thanks to WorldFish, a non-profit research organization for financial support through Blue Economy Challenge Project to conduct this research for harnessing the potential of fisheries and aquaculture to strengthen livelihoods and improve food and nutrition security. Special thanks goes friends Md. Abdul Kadir Zilany for his support for completing my thesis work in laboratory. Finally, I would like to express my very profound gratitude to my parents for all care, unfailing support and continuous encouragement throughout my study. This accomplishment would not have been possible without them.
