TL;DR: Although delta smelt recently performed well enough to meet the current restoration criteria, analyses presented here suggest that there is still a high probability that the population will decline in the near future; the most recent abundance index is the lowest on record.

TL;DR: Examination of trends in abundance of four pelagic fish species in the upper San Francisco Estuary over 40 years using Bayesian change point models found no selected covariates could explain statistically the post-2000 change points for any species.

TL;DR: In many estuaries, maxima in turbidity and abundance of several common species of zooplankton occur in the low salinity zone (LSZ) in the range of 0.5-6 practical salinity units (psu).

TL;DR: The results were relatively robust with respect to the form of stock-recruitment model used and to inclusion of subsidiary covariates but may be enhanced by using detailed state-space models that describe more fully the life-history dynamics of the declining species.

TL;DR: In this paper, the authors proposed a method to improve the salinity of the upper San Francisco Estuary by reducing abundance of non-native species and increasing abundance of desirable species.
