Evaluation of length-weight relationship for a native goby, awaous jayakari (Teleostei: Gobiidae) in the middle east

Parameters of length-weight relationship of freshwater and marine fishes have long been of interest as a longstanding theme fisheries sciences and have been estimated for many fishes around the world. In this study, for the first time, length weight relationship (LWRs) was estimated for a native fish, the long nose goby, Awaous jayakari (Gobiidae) collected from the inland waters of Oman in 2020. The parameter of b for male and female specimens based on standard length (SL) was within the range of 2.666-4.377 and 2.852-3.374, respectively. As proposed for different fishes there was high and significant correlation coefficients with r²≥0.97 between length and weight (0.970-0.983).s Bailey’s ‘t’ test revealed that b value significantly deviated from 3 for both males and females showing their positive allometric growth pattern.
