Length–weight relations of 16 mesopelagic fishes (Actinopterygii: Myctophiformes and Stomiiformes) from the eastern Mediterranean Sea

For many mesopelagic fishes, even basic knowledge regarding their biology is missing, greatly impeding effective management. Here we present length–weight relations for 16 fishes sampled during research surveys in the Greek seas (eastern Mediterranean). The following species were studied: Benthosema glaciale (Reinhardt, 1837); Ceratoscopelus maderensis (Lowe, 1839); Diaphus holti Tåning, 1918; metopoclampus (Cocco, 1829); rafinesquii 1838); Hygophum benoiti hygomii (Lütken, 1892); Lampanyctus crocodilus (Risso, 1810); Lobianchia dofleini (Zugmayer, 1911); Myctophum punctatum Rafinesque, 1810; Notoscopelus elongatus (Costa, 1844); Symbolophorus veranyi (Moreau, 1888) [ Myctophidae ]; Argyropelecus hemigymnus Cocco, 1829; Maurolicus muelleri (Gmelin, 1789) Sternoptychidae Stomias boa Chauliodus sloani Bloch et Schneider, 1801 Stomiidae ].With exception of and , parameter b diverged significantly from isometry. Only two ( ) displayed negative allometry, while remaining 12 a positive allometry was found, with highest values estimated . median value all 3.236 50% its ranged 3.173 to 3.323.
