N2  - An assessment of the use of rice bran as a fish feed was  carried out in four areas in Udon Thani province of the North east  Thailand, representi11g four agro-ecological zones in the region.  The study included a survey of fisl1 farming population in The  selected areas to assess t.li e use of rice bran as a fish feed;  evaluation of rice .bran samples collected from the field in terms  o f the quality; a storage study to evaluate l be quality changes  of rice bran on storage and a case study of two villages to study  The dynamics of rice bran marketing in the villages. Average  area of a fish pond was found to be 1 .16 ha , yielding on an  average 1 5 O O Kg/ha of which 20 . 1 per cent was us e d for home  consumption. The survey confirmed The earlier observation s l hat  rice bran was the most commonly used fish feed being used by 65 %  of the fanners. Farmer ' s awareness of the locally available feed  stuffs was a1so observed. The common fish pond inputs were  vegetables, termites, duck weed, ipomea and cassava leaf.  Differences in fish pond inputs used , reflected local  availability and agricultural practices of Ll1e area. 77 % of  the  farmers were found to use less than 1 Kg of rice bran and 44  % of  the farmers were found to feed rice bran once every day. Limited  availability of rice bran was reported to be the reason for  confining the use of rice bran . The low fish yie1d is attributed  to the low usage of feed inputs of which rice bran is a major  constituent. A clear difference in the proximate composition was  observed between the rough, smooth and mixed rice bran available  to the farmers. A rapid increase in free fatly acid was observed  on storage, indicating development of rancidity which was a major  reason restricting the storage of rice bran . Case study of  marketing of rice bran revealed that the existing marketing  system, was geared to the needs of the village , but the pig and  the duck subsystems were found l o be the major consumers of rice  bran, leaving the fish subsystems at a disadvantage Seasonal  differences in price and availabi1ity was observed depending on  the farming activities ln the village
