Various fish traps made of bamboo and other natural construction materials using indigenous knowledge systems are traditionally employed to catch small economic fishes in low lying areas of West Bengal and Assam. However, in recent years, nylon mosquito netting is gradually replacing bamboo as the main construction materials in case of <i style="">Mugri</i>, a V shaped trap commonly used in East Midnapur district of West Bengal. The paper gives a comparative account of both the original and modified trap as well as their fish catch composition and cost of construction. In contrast, <i style="">Dori, </i>a counterpart of <i style="">Mugri</i> common in neighbouring Assam is still being made of bamboo. The probable causes for the recent change over from bamboo to plastic net as the main construction material in case of <i style="">Mugri</i> and its implication on fish biodiversity and preservation of the ITK and skill associated with construction of this traditional bamboo trap is discussed in the paper.
