Habitat

Clinging to rocks and submerged logs on the bottom of rivers, streams and the delta.

Baits and lures

Worms and dough; bait resting on the bottom.

Recommended gear

Light bottom gear, a small hook with a worm resting on the bottom. Usually an incidental catch; a steady pull on the hook-set.

Fishing techniques

La vieja del agua es un pez acorazado de fondo, con boca de ventosa, que se alimenta raspando algas y materia orgánica de piedras y troncos.

Pesca de fondo con carnada vegetal

  1. Buscá fondos con piedras, troncos sumergidos o zonas con algo de corriente donde suele raspar su alimento.
  2. Armá un aparejo de fondo simple, plomada suficiente para mantener la carnada quieta cerca del sustrato.
  3. Cebá con carnada vegetal —masa, pan, choclo o pasta— o con lombriz, apoyada directamente en el fondo.
  4. Esperá con paciencia: el pique suele ser lento y sostenido, casi como un peso muerto que se mueve despacio.
  5. Clavá con un tirón firme cuando notás que la línea se tensa de forma continua, no con golpes secos.
  6. Peleá con presión constante: no corre ni salta, pero su cuerpo acorazado y la ventosa hacen que se aferre al fondo con fuerza.

También es habitual como captura incidental mientras se pesca de fondo para otras especies, sobre todo en ambientes con piedras o estructuras sumergidas.

Tips de guía: se la encuentra activa tanto de día como de noche, en especial cerca de estructuras con algas visibles. Su cuerpo está cubierto de placas óseas duras: manejala con cuidado para no lastimarte las manos, y sostenela por el cuerpo, no por las placas de los bordes que pueden ser filosas.
