LENGTH-WEIGHT RELATIONSHIPS OF THREATENED SHARK SPECIES FROM THE BRAZILIAN AMAZON COAST
Length-weight relationships are valuable in fisheries biology for estimating a fish's average weight at a given length, aiding in predicting population conditions based on total biomass. This study presents length-weight relationships for six threatened shark species captured off the Brazilian Amazon Coast. The specimens of Carcharhinus porosus, Carcharhinus oxyrhynchus, Rhizoprionodon porosus, Sphyrna lewini, Sphyrna mokarran, and Sphyrna tudes were caught by commercial fleets using gillnets with a mesh size of 95-100mm in three distinct periods: from 1997 to 1999, from 2010 to 2012, and from 2018 to 2019. The values of parameter b ranged between 2.98 and 3.28. Keywords: Fishery biology, artisanal fishery, allometry, elasmobranchs
