Title
The effects of early hypersaline acclimation due to climate change on the toxicity of pyrethroid, an insecticide, in salmonids.
Lead
University of California - Riverside [UC Riverside]
Description
Sea level rise and drought are expected to result in hypersaline waterways in the Delta. Endangered Chinook salmon and Steelhead trout go through smoltification to be able to live and mature in saline environments. However, with salinities and temperatures increasing in historically freshwater areas, these fish may be facing new stressors. Pesticide runoff into the Delta is common due to the urbanization and agriculture of many regions and can adversely affect fish. Additionally, previous research has shown that salinity exposure increases the toxicity of contaminants in anadromous fish, and it is had been demonstrated that bifenthrin, a common insecticide in the Bay, can have endocrine disrupting effects on juvenile salmonids. This project will examine the impacts of hypersaline conditions, various temperatures, and exposure to bifenthrin on the development and survival of juvenile Chinook salmon and Steelhead trout. Specifically, it will: Test the impacts of premature hypersaline acclimation and temperature on the survivial and smoltification process of a range of juvenile salmonids; Test the combined impacts of premature hypersaline acclimation, temperature, and bifenthrin exposure on smoltification, survival and behavior;and Predict the population level effects of drought and pesticide runoff on the health of endangered salmonids Additionally, this research will provide information to CA Department of Pesticide Regulation for potential pesticide management in the Delta, as well as to the CA Department of Fish and Wildlife for conservation practices of endangered juvenile salmonids in the Delta.

Quantifying the contribution of tidal flow variations to survival of juvenile Chinook salmon
Lead
U.S. Geological Survey [USGS]
Description
The purpose of this project is to quantify how tides in the Delta influence survival of juvenile salmon. Juvenile salmon survival increases when there is more flow and the river is less tidally influenced. We hypothesize that the increase in survival is because of reduced travel times causing less exposure to predators. This project will test this hypothesis using multiple models including ones that can predict how management actions that modify tidal patterns affect juvenile salmon survival.

Suisun Marsh Salinity Control Gate Study
Lead
California Department of Water Resource [DWR]
Description
Description Suisun Bay and Marsh are a key part of the habitat for Delta Smelt, but during drier periods such as summer, Delta Smelt may be at least partially excluded from Suisun Marsh due to high salinities. The purpose of this proposal is to provide scientific support a management action for Smelt, operation of the Suisun Marsh Salinity Control Gates (SMSCG). This facility is currently to tidally pump water into the Marsh to improve fall and winter habitat conditions for waterfowl, but could also provide a tool to manage aquatic habitat for Delta Smelt in other periods. Specifically, by using the SMSCG to direct more fresh water in Suisun Marsh, our prediction is that reduced salinities will improve habitat conditions for Delta Smelt in the region. Need The status of Delta Smelt is dire. As part of the Resources Agency's Delta Smelt Resiliency Strategy, in August 2018 we conducted pilot operations of the SMSCG to support Delta Smelt , with promising results. Based on this early success, we expect that the SMSCG will be used as a seasonal tool to support Delta Smelt in summer-fall in coming years as part of the coming FWS Biological Opinion and DFW ITP. Neither has been completed, but SMSCG operations for fish are expected to be required in each. Hence, the proposed study is intended to provide a scientific evaluation and guidance for an expected SMSCG action in 2020. Objectives The primary objective of this project is to evaluate the effectiveness of the SMSCG action. Questions to be addressed include: • Did the action improve habitat conditions for Delta Smelt in the Suisun Region? • Does the Suisun Region typically have better habitat and food web conditions than the upstream River Region? • Do Delta Smelt respond favorably to the SMSCG flow action? • Does operation of the SMSCG affect other fishes and clams?

Extracting Better Information from Long-Term Monitoring Data: Estimating Occupancy and Abundance of Near-Shore Fishes in the Sacramento-San Joaquin River Delta
Lead
U.S. Fish and Wildlife Service [USFWS]
Description
Description The purpose of this study is to expand IEP monitoring and inference to other dominant near-shore, littoral habitats not sampled by beach seines through the use of boat electrofishing. To accomplish this we will sample key littoral fish species across various near-shore habitats in order to determine how best to estimate abundance, occupancy, capture probabilities, and related environmental drivers. Need Expanding DJFMP sampling to other habitats throughout the Delta will allow our program to detect and monitor fishes and ecological trends through time, alleviating a recognized data gap. Current sampling relies on data collected through non-random fixed point sampling of unobstructed habitats, which limits the utility of our data to inform management decision. Objectives • Design boat electrofishing survey methods to expand DJFMP’s monitoring into habitats and locations not sampled by beach seining. • Design and develop field and data analysis methods for estimating capture probability and abundance using boat electrofishing techniques. • Predict spatio-temporal distribution of habitats occupied by key littoral species.

Marine Invasive Species Program [MISP]
Lead
California Department of Fish and Wildlife [CDFW]
Description
The Marine Invasive Species Program (MISP) is responsible for analysis of shipping vectors (pathways) responsible for the introduction of non-indigenous species (NIS) into California's coastal waters. MISP has partnered with the Smithsonian Environmental Research Center (SERC) and Moss Landing Marine Laboratories (MLML) to undertake an extensive program to analyze spatial and temporal patterns of NIS invasions in marine and estuarine waters of California. MISP collaborates with the California State Lands Commission (CSLC) to regulate and minimize the introduction of Nonindigenous Species (NIS) into California by ocean-going vessels. MISP is partners with the Smithsonian Environmental Research Center (SERC) to conduct biological surveys monitoring the coastal waters of California to determine the level of invasion by NIS;and San Jose State University's Moss Landing Marine Labs (MLML) to conduct genetic analysis of NIS. The California Ballast Water Management Act of 1999 initiated baseline surveys by the California Department of Fish and Wildlife (CDFW) to document the distribution of nonindigenous species in the state's coastal and estuarine waters.

Yolo Bypass Fish Monitoring
Lead
California Department of Water Resource [DWR]
Description
California Department of Water Resources (DWR) has operated a fisheries monitoring program in the Yolo Bypass, a seasonal floodplain and tidal slough, since 1998. The objectives of the Yolo Bypass Fish Monitoring Program (YBFMP) are to: (1) collect baseline data on lower trophic levels (phytoplankton, zooplankton, and aquatic insects), juvenile fish and adult fish, hydrology, and water quality parameters;(2) investigation of the temporal and seasonal patterns in chlorophyll-a concentrations, including whether high concentrations are exported from the Bypass during agricultural and natural flow events and the possibility of manipulating bypass flows to benefit listed species like Delta Smelt (Hypomesus transpacificus) and Chinook salmon (Oncorhynchus tshawytscha). The YBFMP operates a rotary screw trap and fyke trap, and conducts biweekly beach seine and lower trophic surveys in addition to maintaining water quality instrumentation in the bypass. The YBFMP serves to fill information gaps regarding environmental conditions in the bypass that trigger migrations and enhanced survival and growth of native fishes, as well as provide data for IEP synthesis efforts.

Restoring tidal marsh foodwebs: assessing restoration effects on trophic interactions and energy flows in the San Francisco Bay-Delta
Lead
University of California - Berkeley [UC Berkeley]
Description
The objective of this research on tidal marsh food webs is to examine whether and how restoration (via breaching dikes) may translate into recovery of diverse energy pathways and trophic interactions between basal resources, primary consumers, and predators. By comparing food webs at several tidal marshes, I will answer the following questions: (1) How does food web structure vary between reference and restored tidal marshes over time (seasons and years) and across a salinity gradient? (2)What mechanisms explain variation in food web structure within and between reference and restored tidal marshes–are they related to energy flows (food quantity, quality, transfer efficiency), community composition, or both? (3) What role do non-native species play in potentially shifting food web structure–e.g., changing community membership, sequestering energy from natives? This project builds on a large breadth of research that has used stable isotopes to characterize tidal marsh food webs in the Bay-Delta and other regions.

Examining the relationship between Longfin Smelt and flow in the San Francisco Bay Delta
Lead
University of California - Berkeley [UC Berkeley]
Description
The overarching goal of this study is to investigate the time-varying effects of flow variation and food availability on longfin smelt population dynamics, via advanced modeling of a diverse set of environmental and ecological monitoring time series. Specifically, this project will:(1) Assess how key environmental drivers (flow, salinity, temperature) have changed over the past 5 decades (1967 to present) across the San Francisco Estuary (SFE); (2) Examine how longfin smelt population dynamics have changed over that time period, and whether/when breakpoints in abundance and trends exist (e.g., periods of 'decline' vs' stability'); (3) Quantify the effects of environmental on driving observed fluctuations in longfin smelt dynamics; (4) Determine whether/how environment-smelt relationships have changed in magnitude or sign over time; and if they changed, whether such changes have been spatially consistent across the SFE. These goals will inform ongoing conservation efforts of longfin smelt by determining the combinations of flow, habitat, and prey availability conditions that lead to stable population dynamics for the species.

From Microbes to Zooplankton, What Defines a Beneficial Wetland?
Lead
San Francisco State University, Estuary & Ocean Science Center
Description
Our study will characterize species diversity at multiple levels of biological organization in the water column of restoring wetlands in the upper San Francisco Estuary and Delta (SFE), from bacteria to fishes. In doing so, we will also describe the foodweb benefits being provided to larval fishes, including longfin smelt, through additional dietary DNA analysis. We will use the species diversity we find in the water column to identify a subset of biota that are indicative of the conditions present in wetlands in different stages of restoration (early, intermediate, and mature) and identify connections between those indicators to the foodweb resources being provided to higher trophic levels. We will study 3-4 wetlands in each of 3 stages: early (unvegetated), intermediate (partially vegetated and partially channelized), and mature (fully vegetated and channelized) wetlands.
