“…The length-weight relationships of U. sulphureus have been studied from different regions of India (Ali, 1978;Reuben et al, 1994;Adarsh and James, 2016) and the World (Prayitno et al, 2020;Vahabnezhad et al, 2020;Clarito and Suerte, 2021). The length-weight relationships of P. heptacanthus have been studied from Tuticorin by Karuppasamy et al (2019). Such information on these species is lacking from the southeast Arabian Sea and this study aims to provide information on the lengthweight relationship (LWR) of U. guttatus, U. sulphureus and P. heptacanthus from these waters.…”
