About Nase fishing
The southern straight mouth nase is a slender benthopelagic freshwater fish belonging to the family Leuciscidae and is endemic to the Iberian Peninsula. It features an elongated fusiform body with silvery flanks, a distinctively prominent snout, and a straight inferior mouth equipped with a hard horny edge designed for scraping algae and periphyton. Reaching typical adult lengths around twenty five centimetres and a maximum standard length of forty centimetres, this schooling species inhabits perennial lowland rivers, middle stretches with moderate current, and large reservoirs. Adults feed primarily on periphyton, plant matter, and benthic invertebrates, undertaking pre-reproductive upstream migrations to shallow gravel beds during spring before spawning.

How to catch Nase
Tips for catching Nase
Anglers target this species primarily in the middle reaches of rivers and transitional reservoir zones during daylight hours when active grazers feed over stony substrates. Success relies on delicate presentations using fine tackle, light floats, or sensitive quiver tips to detect subtle bites from fish browsing near the bottom. Effective approaches involve lightweight float fishing and fine feeder tactics close to riffles or current seams where fish gather before spawning runs. Natural offerings such as small sections of worms, bread paste, or sweetcorn work best to tempt their specialised mouths, while pre-baiting helps concentrate school activity in chosen swims during spring and early summer.
