Reproductive Biology of Snow Trout Shizothorax plagiostomus

A study on the seasonal cyclicity of ovarian development in adult Himalayan snow trout, Schizothorax plagiostomus

“…Numerous reports are available on the oocyte maturation and ovarian development in freshwater teleosts (Basu et al ., 2004; Chaube et al ., 2022; Malison et al ., 1994; Shein et al ., 2004; Singh et al ., 2008). Nonetheless, limited studies have been undertaken till date to understand the ovarian cyclicity of Cyprinidae fishes (Hliwa et al ., 2017; Manorama & Ramanujam, 2017; Sivakumaran et al ., 2003), including Schizothoracine species like Schizothorax richardsonii (Agarwal et al ., 2004; Bisht & Joshi, 1975; Ciji et al ., 2021; Joshi et al ., 2016), Schizothorax labiatus (Arafat & Bakhtiyar, 2022; FAROOQ et al ., 2018; Farooq et al ., 2019), Schizothorax niger (Hussain et al ., 2018; Malhotra, 1970; Sabha et al ., 2017), Schizothorax curvifrons (Qadri et al ., 2019; Sunder, 1984), Schizothorax plagiostomus (Agarwal & Singh, 1991; Arif et al ., 2019; Jan & Ahmed, 2019; Pasha et al ., 2016; Shrestha & Khanna, 1979; Singh et al ., 2016). Furthermore, the nomenclature and terminology used for identifying the ovarian developmental stages/maturational phases in teleost fishes by various authors are overlapping, and thus remain indistinct and confusing (Agarwal et al ., 2004; Agarwal & Singh, 1991; Arafat & Bakhtiyar, 2022; Arif et al ., 2019; Bisht & Joshi, 1975; Ciji et al ., 2021; FAROOQ et al ., 2018; Farooq et al ., 2019; Hliwa et al ., 2017; Hussain et al ., 2018; Jan & Ahmed, 2019; Joshi et al ., 2016; Malhotra, 1970; Manorama & Ramanujam, 2017; Pasha et al ., 2016; Qadri et al ., 2019; Sabha et al ., 2017; Shrestha & Khanna, 1979; Singh et al ., 2016; Sivakumaran et al ., 2003; Sunder, 1984).…”
