Taxonomy and nomenclature
Distribution and habitat
Although locally associated with the nile and fresh water bodiesin Pakwach District, Brycinus nurse has a broader natural distribution across African freshwater systems, including the nile basin, Lake Albert, and neighboring river nwtworks. It is a fresh water species typically found in less salin waters such as rivers and lakes.[1]
Description
Nangnang is a small to medium fish with generally greyish body and a hint of golden tones when fried or fresh. It is consumed by various ethnic groups in the West Nile region, including the Alur people. The species is often harvested in large numbers due to its schooling behavior and relative abundance in suitable freshwater habitats.[1][3] It is found in less saline waters such as the White Nile[6] and fresh rivers.[7] It is a crunchy snack that is served on the move. During preparation, the fish is washed, sorted into different sizes and then deep fried from silver-grey to golden brown.[6]
Ecology and biology
Brycinus nurse is an omnivorous freshwater fish that feeds on variety of aquatic plants such as zooplankton, insects, and small invertebrates. Studies from other regions indicate that this diet contributes to its ecological success across diverse river and reservoir environments. The species grows to moderate lengths typical of small pelagic fish and undergoes spawning during wet seasons in many parts of its range, including reproductive cycles influenced by flooding and seasonal water changes.[5]
