Project: Mechanisms Underlying the Flow Relationship of Longfin Smelt: I. Movement and Feeding

Description: The project is to apply modern analytical methods, bioacoustic detection and particle tracking models to refine understanding of the vertical and longitudinal distribution of longfin smelt (Spirinchus thaleichthys) and how they are affected by flow and food availability. Funding will be used to conduct the research to protect and maintain the estuary's threatened longfin smelt population.

Reference Number: 3600BP1696013

Implemented By: San Francisco State University

Objective: Objectives are to: 1) Determine the cureent and historical longitudinal, lateral, and depth distribution of longfin smelt. 2) Determine how diet of longfin smelt varies with food availability, habitat, and region. 3) Determine how export losses, transport to and retention in rearing areas, and distribution vary with X2. 4) Determine which mechanisms for the strong X2 relationship are supported by the available evidence.
