Length-length relationships for six pelagic shark species commonly caught in the southwestern Atlantic Ocean

This study reports length-length relationships between Fork Length, Precaudal Length and Total Length for the main six pelagic species (Prionace glauca, Carcharhinus brachyurus, Carcharhinus signatus, Sphyrna zygaena, Isurus oxyrinchus and Lamnanasus) captured by pelagic longline fisheries in the southwestern Atlantic Ocean. The length-length relationships provided in this contribution covers an extended portion of the reported size range of each species considered, and represents the first length-length conversions ever reported for these species in the region.
