Comments: The intensive dispersal of the species in Luzon in the 1970s led to the displacement of the native catfish in irrigation systems, lakes and rivers (Ref. 48328). Has completely dominated natural populations in lakes and rivers and the indigenous Clarias macrocephalus can hardly be found in the markets today. Grows better than local species but not as acceptable. (Ref. 1739). The species has successfully established in Luzon, Mindoro, Negros, Panay and some parts of Mindanao (Ref. 48328). Also recorded from Paitan Lake, Pantabangan Dam, and Tabuating River (Nueva Ecija) (Ref. 109918).     Ref:  Welcomme, R.L., 1988
