Young-of-the-year fish made up an estimated 49-62% (bar|x = 54) of the PT. According to the food production/food consumption budget calculated by three different methods, less than half of the PT is of autochthonous origin, while most is from other sources. Floodplain fish production includes two components: fish originating within the floodplain and fish that are temporary immigrants. The latter component varies considerably in response to the hydrological regime. To assess the PT in riverine ecosystems, different seasons and years are needed to give realistic values.
