Transcriptomic analysis provides insight into the mechanism of salinity adjustment in swimming crab Portunus trituberculatus

Background Low salinity is one of the main factors limiting the distribution and survival of marine species. As a euryhaline species, the swimming crab (Portunus trituberculatus) is adaptive to relatively low salinity. However, the mechanisms underlying salinity stress responses in P. trituberculatus is not very clear.
