Abstract
The present research provides length-weight relationship (LWR) of eight fish species included Pomadasys stridens (ForsskA¥l, 1775), Epinephelus areolatus (ForsskA¥l, 1775), Pristipomoides multidens (Day, 1871), Pomadasys maculatus (Bloch, 1793), Johnius borneensis (Bleeker, 1851), Diagrmma pictum (Thunberg, 1792), Epinephelus malabaricus (Bloch & Schneider, 1801) and Epinephelus coioides (Hamilton, 1822) from Chabahr fishing grounds (latitude 25° 11’ to 25° 12’ N; longitude 60° 04’ to 60° 13’ E) in the Sea of Oman. All fish specimens were caught using midwater trawl net, with 65 mm mesh size in the cod-end, from April to May 2016 during the spring season. The LWRs for fish species were W = 0.0127L2.874 for P. stridens, W = 0.0153L2.971 for E. areolatus, W = 0.0227L2.873 for P. multidens, W = 0.0534L2.689 for P. maculatus, W = 0.0023L3.157 for J. borneensis, W = 0.0164L2.807 for D. pictum, W = 0.0487L3.287 for E. malabaricus, and W = 0.0487L3.287 for E. coioides, respectively.
Highlights
Length-weight relationships are fundamental information to understanding the biological parameters of fishes for fisheries management, fish stock assessment, determination of biomass using measured weights, comparison of life cycle characteristic of fish populations from different regions, and estimation of weight ranges from length ranges [1,2,3,4]

Summary
Length-weight relationships are fundamental information to understanding the biological parameters of fishes for fisheries management, fish stock assessment, determination of biomass using measured weights, comparison of life cycle characteristic of fish populations from different regions, and estimation of weight ranges from length ranges [1,2,3,4].
