IUCN red listed Ompok bimaculatus rearing plays pivotal role in aquaculture. Inclusion of diets with attractants as an alternative for the cellulose replacement gives hope to rear the carnivore species with lesser mortality. Chemo-attractants like betaine, inosine monophospahte, DL-alanine, tryptophan can be supplemented in diet which results in growth increament in fish. The fishes can feed with supplementation with natural attractants viz. dried tubifex, dried earthworm and fish meal. Attractant supplementation in diet results in the improvement in terms of weight gain, specific growth rate (SGR), total biomass and performance index and survivability. Right inclusion rate of suitable attractant (or in combination) at right stocking density for optimum days has to be worked out in region specific manner to bridge the gap of demand and supply of this IUCN red listed species.

Key words: Ompok bimaculatus, Attractants, Chemo-attractant, Natural attractant, L-tryptophan, Betaine.
