The African catfish (Clarias gariepinus, C. lazera) made Zarraga famous because of the proliferation of African catfish in that area. Their produce are sold along the highway of the town for about P90 a kilo. Now That a provincial freshwater fisheries development program is being implemented by the Iloilo provincial government, the aquaculture department of the Southeast Asian Fisheries Development Center (Seafdec), the Bureau of Fisheries and Aquatic Resources and Pototan Municipal Agriculture and Fisheries Council (MAFC) is proposing a Native Catfish Industry Development for the municipality of Pototan.
