Assessment of applicability of Indigenous Technical Knowledge (ITK) in aquaculture as perceived by fish farmers in Assam

摘要

This paper examines the applicability of Indigenous Technical Knowledge (ITK) relating to aquaculture in Assam and it specifically emphasises the effectiveness as well as constraints perceived by the fish farmers in practicing the ITKs. The study was conducted in Nagoan District of Assam in the year 2012-2013 and is based on primary data collected through personal interview using semi-structured interview schedule, focus group discussion and observation methods. The ITKs studied are related to pond preparation and renovation, water quality management, stocking, feed management,disease and pest control, piscicidal plants/fish attractants used for catching fishes and post-harvest operations. Rationality and effectiveness of the ITKs were also assessed. The study identified and ranked nine constraints as perceived by the fish farmers and documented their suggestions to overcome the constraints so as to conserve the ITKs for wider application in aquaculture systems. Further, the study recommends the need for validation, refinement and popularisation of the ITKs.
