Known in Thailand as pla cha-on (ปลาชะโอน), it is one of the very similar catfish species known in the markets as pla nuea on (วงศ์ปลาเนื้ออ่อน). It is valued for its delicate flesh and is also used for making high-quality fish balls. [4] [ additional citation(s) needed ]O. bimaculatus reaches a maximum length of 45 cm. [3] The International Union for Conservation of Nature has classified this species as near threatened due to limited data suggesting overfishing and possibly widespread population declines, noting uncertain identities of populations classified as O. bimaculatus and concluding that there is an "urgent need for taxonomic, harvest and population studies".
