Value chain analysis of tilapia fish seed in some selected areas of Mymensingh district in Bangladesh

Bangladesh is now ranked 5 in world aquaculture production (FAOSTAT, 2016). The fisheries sector is contributing to a very significant role in the agrarian economy of Bangladesh. It contributes 3.57 percent to our national GDP and around one-fourth (25.03 percent) to the agricultural GDP (Bangladesh Economic Review, 2018). Fish alone supplements about 60 percent of animal protein in our daily diet (FAO, 2016). The total fish production in FY 2015-16 stood at 38.78 lakh MT and that reached at 41.34 lakh MT in FY 2016-17 (DoF, 2017). In Bangladesh, tilapia was introduced from Thailand and contributes 8.1 percent of total aquaculture production (ADB, 2005; Rahman, 2012). Due to its rapid growth rate and high market value, it has become one of the most popular commercial culturable species in Bangladesh (ADB, 2005; Rahman, 2012). A total of around 201,000 farmers are involved in tilapia culture (DoF, 2017). In the year 2017, the area for tilapia culture reaches around 330,000 ha including ponds, ghers, and floodplains. Tilapia is cultured with different fish species such as African catfish (Ibrahim and Naggar, 2010), Macrobrachiam rosenbergii (Goda Abstract
