Length-weight relationships of seven myctophid fishes (Myctophiformes: myctophidae) in the South China Sea

Abstract

The study included 546 specimens of seven myctophid fish species from the South China Sea (captured during June 2015 by bottom and mid-water trawls). Length-weight relationships (LWRs), W = aLb, were estimated using standard length. The species belong to four genera. The values for the parameter a ranged from 0.006 to 0.022, while the b values ranged from 2.710 to 3.476 (Range of r2 values: .938 to .971). According to FishBase, this study presents the first LWRs for these species, including two maximum standard lengths for Diaphus chrysorhynchus and Notoscopelus resplendens.
