Record 1 2023-06-28

English

Subject field(s)
  • Oceanography

CONT

Boat seines are often used on a smooth seabed with fewer obstructions to reduce net damage. Compared with a trawl net, a seine net usually has longer wings and utilizes long heavy ropes (seine ropes) that extend from the wings of the net through a pair of bridles to increase the area over which fish are herded.

Key term(s)
  • smooth sea bed

CONT

Les sennes halées à bord sont souvent utilisées sur les fonds marins lisses, contenant peu d'obstacles, pour réduire les dommages causés au filet. Par rapport au chalut, la senne a généralement des ailes plus longues et utilise de longs filins lourds attachés aux ailes du filet par l'intermédiaire d'une paire d'entremises pour augmenter la surface de rabattage des poissons.
