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 Mugri, 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, Dori, a counterpart of Mugri
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 Mugri 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.
