highest. Results of two 1969 surveys financed by the Bureau of 



Commercial Fisheries are also reported briefly. One survey

determine their experience with catfish. The second survey 



concerned 1,500 housewives who kept daily diaries of food 



purchases; it showed per capita consumption of fish products by
