The fish marketing system in Bangladesh is traditional, but it plays a vital role in connecting the farmers and consumers, thus contributing significantly in the value adding process. The demand for low-value cultured fish is high in markets due to low price and increases in population but supply is limited, and a strong network has developed with intermediaries and traders intervening between farmers and consumers. The prices of low-value fish depend on species, quality, size and weight, seasonality, supply and demand, location of markets, and market infrastructure. The marketing of low-value cultured fish play an important role to increase food supply.
