Length-weight relations of 70 fish species (actinopterygii) from tropical coastal region of Pernambuco, Northeast Brazil

The presently reported study provides length-weight relations (LWR) of 70 fish species (Actinopterygii) from the tropical coastal region of Pernambuco, Northeast Brazil: Achirus declivis, Achirus lineatus, Anchoa spinifer, Anchoa tricolor, Anchovia clupeoides, Archosargus rhomboidalis, Aspistor luniscutis, Aspistor quadriscutis, Bagre bagre, Bagre marinus, Bairdiella ronchus, Bathygobius soporator, Carangoides bartholomaei, Caranx hippos, Caranx latus, Caranx ruber, Centropomus parallelus, Centropomus pectinatus, Centropomus undecimalis, Chaetodipterus faber, Chloroscombrus chrysurus, Citharichthys spilopterus, Conodon nobilis, Ctenogobius boleosoma, Cynoscion virescens, Diapterus auratus, Diapterus rhombeus, Engraulis anchoita, Etropus crossotus, Eucinostomus argenteus, Eucinostomus gula, Eucinostomus havana, Gobionellus oceanicus, Gobionellus stomatus, Haemulon plumierii, Isopisthus parvipinnis, Larimus breviceps, Lutjanus alexandrei, Lutjanus analis, Lutjanus jocu, Lutjanus synagris, Lycengraulis grossidens, Macrodon ancylodon, Menticirrhus americanus, Micropogonias furnieri, Mugil curema, Mugil liza, Nebris microps, Opisthonema oglinum, Paralonchurus brasiliensis, Pellona harroweri, Polydactylus virginicus, Pomadasys corvinaeformis, Rhinosardinia bahiensis, Sciades herzbergii, Selene brownii, Selene vomer, Sparisoma radians, Sphoeroides greeleyi, Sphoeroides testudineus, Sphyraena guachancho, Stellifer brasiliensis, Stellifer microps, Stellifer rastrifer, Stellifer stellifer, Symphurus plagusia, Symphurus tessellatus, Thalassophryne nattereri, Trichiurus lepturus, and Trinectes paulistanus. Data were collected between 2011 to 2014, using different fishing gears. The variation of the b coefficient for the majority of species felt within the expected range of 2.5 < b < 3.5. Additionally, this work provides the first LWR values for 3 fish species: Lutjanus alexandrei Moura et Lindeman, 2007; Rhinosardinia bahiensis (Steindachner, 1879); and Thalassophryne nattereri Steindachner, 1876
