Means and standard deviations (SDs) for catch in number (CPUEn) and weight (CPUEb) per unit of effort (per 1000 hooks), mortality (MPUE) per unit of effort 
(1000 hooks) by species and species groups caught by using 2 different leader materials, 2.5-mm monofilament nylon and 1.2-mm multifilament stainless wire, 
during experimental longline sets conducted in the southwest Indian Ocean between November 2013 and March 2014. Other values given are number of specimens 
caught (no.); frequency of occurrence (FO), measured as a percentage; discards (Disc), measured as a percentage; dead discards (DD), measured as a percentage; 
and the value per unit of effort (per 1000 hooks) of the retained catch (VPUE), given in U.S. dollars ($) and euros (€).
