Kasa (Tai Dam Triangle Dip Net) — a Triangular-Mouthed Net Knitted from Thread with a Chun, 140 cm Long, 100 cm Mouth; Women Stand in a Diagonal Line to Scoop Fish

"The women stand in an orderly diagonal line across a canal that is not too deep; each sets the edge of her kasa against the bottom, and the current carries the fish into the kasa." (Sirindhorn Anthropology Centre, author พิชชา ทองขลิบ (Phitcha Thongkhlip), CC BY 4.0)

Wind thread onto a chun netting needle and knit open mesh from the bottom of the net up to the mouth edge, about 140 cm long, with a mouth about 100 cm across.

Bend bamboo into a rounded triangle for the mouth frame.

Thread rattan along the mouth edge of the finished netting and tie it to the bamboo frame.

Fish in a group of 7-8 up to 40-50 people, standing in a diagonal line across a shallow canal, each kasa's edge set against the bottom, so the current carries fish in. Those at the acute corner have the advantage, so everyone rotates positions for fairness. The main season is after the main rice harvest, about January to February.

Fishing with the kasa is a shared activity of Tai Dam women that builds solidarity and equal access to resources; men fish alone with cast nets. The kasa is also used in the rite of scooping back the soul of the sick or injured, and at funerals. Beware of slipping when standing in the canal.
