Fishing rhythms

The fishing at the bandh Wall happens in unison with the 28-day lunar cycle. Each of these transitions is observed and recorded as cultural anchors called the Purnima, Amavasya and Ekadashi.
We look at the cycle from the full moon day called the Purnima. The bamboo placed around 100ft away from the bandh essentially acts as tidal markers. Fishing is not practised on the full moon night as a heavy current flows through the sluice gate. Soon, the tide starts to retreat and the darker patches of the bamboos emerge and reveal the imminent low tide. The fishermen look for this marker to lay their nets. A few hours later, the water current reverses and brings out the fish from the poiem. The eleventh day, culturally called the Ekadashi brings another high tide. The incoming current runs in the crabs. They are baited with shark meat. Fish which are brought near the sluice gate can sense a 'sweeter' water body and enter the inner side of the bandh. The poiem now acts as a nursery for the newer fish. 
The incoming low tide shows drastically low levels of water and shallow grounds. The amavasya or the new moon night brings the maximum low tide. 
Low tides are a fisherman's feast. Prawns, chonak and rat snipers fall prey to the practised hands. 
A few villagers still continue to catch crabs on every high tide. The monthly cycle ends with the Purnima, when the high tide reaches its peak, it makes fishing unviable. 
Culturally, a vegetarian diet is also followed on this day. This helps us link the lunar cycle with anthropocentric practices.
