About Ruivaco fishing
The ruivaco is a small freshwater ray-finned fish belonging to the family Leuciscidae and the genus Achondrostoma. Endemic to Portugal, it features a fusiform body shape with a typical total length of around fifteen centimetres and a maximum length reaching twenty-five centimetres. This benthopelagic species inhabits slow-moving, low-lying coastal rivers, streams, and terminal segments of main river basins possessing aquatic vegetation and substrates of sand or gravel. Operating primarily as an omnivorous generalist, its diet consists heavily of detritus and plant material supplemented by aquatic insect larvae such as dipterans and coleopterans. Populations face ecological pressures from habitat destruction and pollution within their limited native range.

How to catch Ruivaco
Tips for catching Ruivaco
Target this small endemic cyprinid in slow-flowing lower river sections and marginal weed beds using light tackle suited for delicate bites. Float fishing with fine line, a small quill float and a tiny hook baited with fragments of worm or single maggots yields steady catches in shallow gravel-bottomed runs. Keep presentation subtle and use groundbait sparingly to draw fish from aquatic vegetation without filling them up.
