The African Catfish in Ganges has become a serious concern for fishermen and environmental experts in Bihar. A recent survey by Patna University found a sharp decline in native fish species in the Ganges near Patna. Experts say the African Catfish in Ganges is one of the main reasons behind this drop.
According to the study, the number of local fish species has fallen significantly in recent years. In some areas around Patna, the population of native fish has dropped by nearly 40–50 percent. Fishermen have also reported smaller catches and fewer fish throughout the year.
Researchers say the invasive African catfish grows quickly and feeds on smaller native fish. This aggressive behavior harms the natural balance of the river ecosystem.
Experts also point to other factors such as pollution, low water levels, pesticide contamination, and illegal fishing practices that add pressure on native fish populations.
Scientists suggest strict action against breeding banned fish species, stronger pollution control, and better protection of river habitats to restore the Ganges ecosystem.
