The Study aimed at measuring the price and quantity relationship between
built and burry fish. The Rotterdam demand model was used to estimate the
price elasticity of demand. Form the study it was concluded that the demand
elasticity was 1.47 for built fish and 1.89 for burry fish . Accordingly, the
Rotterdam demand model proves that there is an inverse relationship
between the price of the commodity and the demand on it. It was also concluded that the net loss of production of the two
commodities was 90.75 and 125.75 million pounds for built and burry
respectively . Second, the net loss of the consumer was 36.97 and 58.93
million pounds for built and burry respectively. Finally, the net loss of the
society was 318.3 million pounds divided to, 139.94 and 184.68 million
pounds for built and burry respectively. On the other hand, the consumer revenue was around 36.87 and
58.94 million pounds for built and burry respectively. The Government
revenue was around 493.94 million pounds divided to, 205.5 and 288.42
million pounds for built and burry respectively.
