The extraction of sand/bajri by engagement of heavy machines is destroying the natural habitat of trout and other fish.
Wastes from dwellings and camps of security forces on the banks of the river, use of pesticides, DDT and insecticides by farmers kills many fish every day.
The change in topography leads to destruction of aquatic fauna of Sind.
In various riverine villages people catch fish through conventional way of angling and using nets. These methods are replaced today by resorting to unconventional and illegal methods. The worst method is using bleaching powder, procured from officials of PHE department. Bleaching powder not only kills fish but other aquatic life as well. This process is very common during summers, especially in Wayil catchment area. The Fisheries Department and other government agencies do not have a high profile intervening.
Mismanagement of water diversion to power canals is another concern for the survival of fish.
