How to catch Duckbill catfish
Sorubim lima (Bloch & Schneider, 1801)
About Duckbill catfish fishing
The duckbill catfish is an elongated freshwater species belonging to the Pimelodidae family, originating from tropical river systems across South America. It features a distinctive flattened, duck-bill-like snout, an elongated body shape, and a muted coloration pattern that provides camouflage among submerged wood and marginal vegetation. Growing to a moderate maximum length and weight, this demersal hunter prefers warm waters and often forms loose schools during daylight hours. As an active nocturnal predator, it feeds primarily on small fish and aquatic crustaceans using its sensitive barbels to locate prey in murky river channels and flooded plains. While primarily known within its native range, it occasionally attracts interest from specialized anglers targeting exotic tropical pimelodids.

When to fish for Duckbill catfish
How to catch Duckbill catfish
Tips for catching Duckbill catfish
Successful angling for this species relies on matching its nocturnal feeding habits and bottom-dwelling nature in warm tropical freshwaters. Target deep river bends, sluggish pools, and areas with heavy submerged structure where schools tend to rest during daylight hours. Bottom fishing with live or dead prawn and small fish baits presented right on the substrate yields the most consistent results. Because these fish hunt primarily after dark using scent and vibration, night fishing sessions significantly increase your chances of success. A sensitive rod tip helps detect the subtle pickup of a cautious catfish before it drops the offering.
