Identification of gynogenetic Megalobrama amblycephala induced by red crucian carp sperm and establishment of a new hypoxia tolerance strain

Blunt snout bream (BSB) is an important economic freshwater fish in China. One of technical bottlenecks in practice lies in improving its hypoxia tolerance. In this study, gynogenesis BSB (GBSB-R) is generated by artificial gynogenesis with UV-inactivated sperms of red crucian carp (RCC), which is regarded as one of freshwater fish with the strongest hypoxia-tolerance. Asynchronous development of the eye pigment further provides an objective...
