Stochastic modeling of production risk and technical efficiency of Thai koi (Anabas testudineus)farming in Northern Bangladesh

Thai koi is one of the high commercially valued farm fishes which have expanded tremendously in the northern part of Bangladesh. However, despite its impressive growth in the initial years, output of the industry is highly volatile across different years and farms. This research, following the Just...
