Estuary ecosystem is usually productive and can provide diverse ecosystem services, however, it is vulnerable to the effects of human activities. Effective assessment of estuary ecosystem health can provide the scientific basis for understanding the status and sustainability of the ecosystem. In this study, we reviewed theories on health assessment of estuary ecosystem, e. g. characteristics, conception and criterion, and summarized the index, technology and evaluation models as well as the rules for index choosing in the present applications. The technology of remote sensing (RS) and geographic information system (GIS) were additionally emphasized. Considering the existing difficulties in the health assessment of estuary ecosystem, we proposed a possible trend of development in this field. New technologies along with the concept, impact mechanism and spatial scale setting were suggested to be further strengthened in the future researches of estuary ecosystem health evaluation. © 2014, Editorial Board of Chinese Journal of Ecology.

The amphipod crustacean Eogammarus sinensis has useful features that make it suitable for use in the aquaculture of fish and large decapod crustaceans. In this study, we investigated the effects of temperature and salinity on the development, fecundity, survival, and growth rate of E. sinensis. The results show that temperature significantly affected E. sinensis development, but salinity. As temperature increased, the duration of E. sinensis embryonic development decreased. Fecundity was affected significantly by temperature and the combination of temperature and salinity, but by salinity alone. In addition, high temperatures accelerated E. sinensis juvenile growth rates, whereas high salinity reduced it. Therefore, our data suggest that E. sinensis tolerates a wide range of salinities and that temperature has more significant effects than salinity on the embryonic development, fecundity, and growth of E. sinensis. Our results shall be useful for mass production of this species for use in aquaculture. © 2013 Chinese Society for Oceanology and Limnology, Science Press and Springer-Verlag Berlin Heidelberg. Source
