As Dr. Bullough said, the discovery of sex reversal in rice field eel indeed opened a fresh field for sex determination study after several decades in vertebrates, especially in fishes. Up to the present day, a large number of significant breakthroughs have been achieved from the genetic basis to the biotechnological manipulation of fish sexual dimorphism and sex determination (Gui and Zhu, 2012; Gui, 2015a; Mei and Gui, 2015). Because some aquaculture fishes exhibit significant sexual dimorphism in growth rate and body size, there are remarkable economic benefits by producing all-females or all-males for aquaculture, and several generations of fish genetic breeding scientists in the Institute have developed a series of sex control breeding biotechnologies to obtain mono-sex populations. Through heterologous sperm-induced gynogenesis and various reproduction mode utilization, three new unisexual all-female varieties, such as allogynogenetic gibel carp (Jiang et al., 1983), high dorsal allogynogenetic gibel carp (Zhu and Jiang, 1993), and allogynogenetic gibel carp “CAS III” (Wang et al., 2011), were bred in gibel carp and applied to aquaculture practice throughout China (Gui and Zhou, 2010; Gui and Zhu, 2012). By artificial gynogenesis and chromosome set manipulation, all-female hybrid common carp was also produced (Wu et al., 1986). Moreover, some sex-specific or sex chromosome-specific genetic markers were identified from yellow catfish and other bagrid catfish (Pseudobagrus ussuriensis) (Wang et al., 2009; Dan et al., 2013; Pan et al., 2015), and all-males of yellow catfish had been massively produced and used for commercial aquaculture (Liu et al., 2013; Gui, 2015b).
As a pioneer of sex determination studies in vertebrates and a founder of freshwater ecology in China, Dr. Liu has made significant contributions to fish biology, lake ecology, and sustainable aquaculture industry. As his fellow scholars, we would like to express our deepest gratitude for his leading role as a front-runner of sex determination studies in fish and express our devout wishes for his health and for his long life.
