Length–weight relations of 39 continental-shelf and deep-water fishes (Actinopterygii) from northwestern Gulf of México

Fishes from the northwestern Gulf of Mexico were surveyed during four oceanographic campaigns (February and October 2016, June September 2017) using a shrimp trawl net benthic sled in 20 locations at depths that ranged 43 to 3608 m. Length–weight relations (LWR) estimated for 39 fish species (in alphabetical order): Bembrops gobioides (Goode, 1880); Centropristis philadelphica (Linnaeus, 1758); Chauliodus sloani Bloch et Schneider, 1801; Chlorophthalmus agassizi Bonaparte, 1840; Chloroscombrus chrysurus 1766); Citharichthys spilopterus Günther, 1862; Coelorinchus caelorhincus (Risso, 1810); Cyclopsetta chittendeni Bean, 1895; Cyclothone alba Brauer, 1906; braueri Jespersen Tåning, 1926; pseudopallida Mukhacheva, 1964; Dibranchus atlanticus Peters, 1876; Epigonus pandionis (Goode 1881); Fowlerichthys radiosus (Garman, 1896); Laemonema goodebeanorum Meléndez Markle, 1997; Lagocephalus laevigatus Lepophidium brevibarbe (Cuvier, 1829); Lutjanus campechanus (Poey, 1860); Malacocephalus occidentalis Goode 1885; Merluccius albidus (Mitchill, 1818); Micropogonias furnieri (Desmarest, 1823); Monolene sessilicauda Goode, 1880; Ogcocephalus declivirostris Bradbury, 1980; Peristedion greyae Miller, 1967; Porichthys plectrodon Jordan Gilbert, 1882; Prionotus longispinosus Teague, 1951; paralatus Ginsburg, 1950; Pristipomoides aquilonaris Rhynchoconger flavus Sardinella aurita Valenciennes, 1847; Saurida brasiliensis Norman, 1935; Sternoptyx diaphana Hermann, 1781; Symphurus diomedeanus 1885); Synagrops bellus Trachurus lathami Nichols, 1920; Trichiurus lepturus Linnaeus, 1758; Trichopsetta ventralis Urophycis cirrata Zalieutes mcgintyi (Fowler, 1952). The studied represented 28 families Antennariidae, Batrachoididae, Bembropidae, Bothidae, Carangidae, Chlorophthalmidae, Congridae, Cyclopsettidae, Cynoglossidae, Dorosomatidae, Epigonidae, Gonostomatidae, Lutjanidae, Macrouridae, Merlucciidae, Moridae, Ogcocephalidae, Ophidiidae, Phycidae, Sciaenidae, Serranidae, Sternoptychidae, Stomiidae, Synagropidae, Synodontidae, TetraodontidaeTrichiuridae, Triglidae. A new maximum standard length (SL) was recorded , C. . positive allometric growth reported nine species, negative 16 isometric 14 species.
