Length-Weight Relationships and Other Morphological Traits of Fishes in the Mangrove of Hainan, China

Abstract

The length–weight relationships (LWR) and other morphological traits for 6417 specimens in 74 fish species collected seasonally, from July 2020 to April 2021, in the mangrove of Dongzhaigang Bay, Hainan Province, China, are presented. This involved, for all species, a sample size, and minimum and maximum lengths; in addition, for most species, it involved linear relationships between the standard length and body height and width, the height of the caudal peduncle, the pectoral fin length, and the eye diameter. This extensive coverage of mangrove-resident fish species (as opposed to species using the mangrove only as a nursery) is a first for Hainan. The various morphological traits of the mangrove fish are, for several species, the first to be published since these species’ original descriptions.
