Riverbed Substrate Requirements for Natural Reproduction of <i>Gymnocypris przewalskii</i>

<i>Gymnocypris przewalskii</i> (i.e., Qinghai Lake naked carp) is a migratory fish species that lives in highland brackish water. It is important to understand the abiotic environment required by this fish to reproduce naturally so that its habitat can be protected and the wild populatio...
