Mother fishery Used by local fishermen to refer to sites characterized by densely concentrated, diverse, high-quality fish habitats (deep river scour holes, called duars, clear tributary streams, deep beels, sediment-free khals) and supportive flora (swamp forest, reed swamp, floodplain grasslands). Five mother fisheries have been identified in the region (see Fisheries Specialist Study).
