Rhynchobatus australiae is a species of wedgefish that is vulnerable to overfishing due to their life history characteristics. This study aims to assess the fisheries and biological information of R. australiae in Terengganu waters. Over a span of 3 months, a total of 26 fish were collected from the Pulau Kambing fish landing port in Terengganu. They were analysed to determine the species’ abundance, length frequency distribution, length-weight relationships (LWRs), and growth parameters. The results indicated that the abundance of R. australiae in Terengganu was higher compared with other locations, with a catch per unit effort of 49.05 kg/haul and 9.15 kg/day. The LWRs for males, females, and pooled sexes were a = 0.0057, b = 2.9404; a = 0.0018, b = 3.2078; and a = 0.0029, b = 3.0979, respectively. The von Bertalanffy growth function parameters for males, females, and pooled sexes of R. australiae were determined as k = 0.035, L∞ = 332.825, t0 = -4.495; k = 1.005, L∞ = 43.161, t0 = -2.99; and k = 0.089, L∞=222.412, t0=-2.565, respectively. Male R. australiae exhibited a higher average length than females. This study was limited in terms of the time span the sample size, which may have introduced variability in the results and may not fully represent of the larger fish population. However, the results of this study may serve as preliminary data for understanding the fish population dynamics of R. australiae in Terengganu waters and can guide future research efforts. Future studies should consider a longer period and a larger, more diverse sample size to obtain more accurate estimates of the abundance and size of R. australiae in this region.
