The impact of climate change on Nile Fish abundance and fishery landings in Khartoum state
Author(s): Dr. Elagba HA Mohamed, Asaad Ibrahim
Abstract: The study investigated the impact of climate change on Nile fish production and species abundance in Khartoum State over the period 2001-2015. Data on rainfall, temperature and the Nile level were extracted from the meteorological records. In 2015, total landings of fish in Khartoum was 11782956 Km compared to 529673Km and 6807550Km in 1993 and 2001, respectively. At the highest temperature of 44◦C and 42◦C in 2004 and 2005, respectively, a significant decrease in total catch was detected, when the temperature started to decrease fish catch increased. A drop in total fish catch was detected and correlated with drop in rainfall. Some species of the Nile-fishes like Citharus citharus (Bitkoya) completely disappeared from fish catch. Only 66 species are now available in the main Nile, 95 Blue Nile, 50 in White Nile, 66 in Lake Nubia. Changing fish distributions and abundances will undoubtedly affect the communities of humans who harvest these stocks. More attention should be paid to climate research.
