Background: The development of aquaculture management areas (AMAs) is opined as one of the strategies to ensure sustainable aquaculture. AMAs allows collaborative management of individual fish farms in a coordinated manner within a demarked space, where water resources and aquaculture impacts are shared in an environmentally harmonised way. This study seeks to evaluate the trophic status and develop potential AMAs for the Tono and Vea reservoirs in the Upper East Region of Ghana.Materials and Methods: Reservoir water depth, transparency, chlorophyll-a, nitrate-nitrogen, nitrite-nitrogen, ammonium-nitrogen and phosphorus concentrations was monitored for 15 months (February 2015-April 2016). The trophic status of the water was estimated from the concentrations of the water quality parameters after laboratory analysis. The composite values ob.. View More»
