An Economic Study on Fish Production and Marketing of Wadi El Rayan Lakes, Fayoum Governorate
Lake Wadi El-Rayyan is located in the Fayoum Governorate, spans approximately 35 thousand feddan, and has an average production capacity of about 3403.3 tons, as estimated between 2001 and 2020. Despite its diverse fisheries, its relative significance in Egyptian fish production remains limited, constituting about 0.24%. The research problem stems from insufficient fish production to meet consumer demands, resulting in a food gap of approximately 345.25 thousand tons during the same period. The study aimed to assess the current state of fisheries in Wadi El-Rayyan Lakes. Analysis of fisheries seasonality from 2017 to 2020 revealed extreme fluctuations, with a seasonality coefficient reaching 3.5%. This was based on an annual fishing effort involving around 129 boats, yielding approximately 2674.6 tons. It was observed that the actual production exceeded the maximum sustainable yield (MSY) level. The productivity elasticities of various factors were calculated, with values of approximately 0.061, -0.843, -0.744, and 0.779, leading to a combined elasticity of -0.747. Analysis of absolute marketing margins for fish species in Wadi El-Rayyan Lake showed relative margins ranging from 20% for tilapia fish to 22.8% for silver carp. Producer's shares of consumer pounds ranged from 77% for grass carp to 82.4% for shamus fish, indicating robust marketing efficiency.
