“…Length-weight relationships (LWRs) are of great importance in the area of fisheries research as they are used to predict the condition and growth pattern, as well as calculate the biomass from the length, and to convert growth in length to growth in weight (Froese, 2006;Froese, Thorson, & Reyes, 2014;Froese, Tsiklirans, & Stergiou, 2011;Le Cren, 1951;Sandoval-Huerta, Madrigal-Guridi, Domínguez-Domínguez, Ruiz-Campos, & González-Acosta, 2015). The biology, ecology and life history characteristics of deep-sea fishery resources from the Indian EEZ are scarce and scattered (Deepu, Divya, & Kurup, 2007;Kumar, Thomy, Deepa, Hashim, & Sudhakar, 2016;Sreedhar, Sudhakar, & Meenakumari, 2013;Venu & Kurup, 2002, 2006.…”
