TELUK INTAN, Nov 12 — Whenever the water level of the Kinta River rises during the rainy season, Anuar Osman knows it is time to head to the river and set up belat (traditional fish traps) in anticipation of the arrival of ikan lundu (a type of catfish), which provides him with a supplementary source of income.

For the 49-year-old inland fisherman, catching ikan lundu is not his main occupation but rather a seasonal opportunity that he seizes whenever the fish migrate in schools through the river.

With catches sometimes exceeding 100 kilogrammes a day, the ikan lundu not only fill his traps but also bring in extra income when sold to wholesalers.

Anuar, who also manages an oil palm smallholding, said the large-scale appearance of ikan lundu typically lasts for about a week, depending on the river’s water level.
