Food Web Data for Shasta Reservoir, California, 2024-2025

This data release includes six child items with data related to bioenergetics and food web ecology in Shasta Reservoir from 2024 to 2025. Child Item 1: "Zooplankton and Water Temperature Data". This included data on zooplankton density and production (zooplankton_density.csv, zoop_length.csv, and daphnia_egg_ratio.csv) as well as water temperature vertical profiles (temperature_data_export.csv). Child Item 2: "Fish sampling and biological data". This included fish sampling (fish_sample_events.csv), and biological data such as species, fork length, weight, sex, and maturity (full_fish_data.csv). Child Item 3: "Fish age and growth data". This included a list of all fish sampled (shasta_final_ages.csv), data for each annulus with the corresponding back-calculated fork lengths (scale_radius_regressions.csv and scale_back_calculations.csv). Child Item 4: "Stable isotope data". This included data for all the biological samples sent for isotopic analysis of nitrogen (δ15N) and carbon (δ13C)(combined_si_data.csv). Child Item 5: "Hydroacoustic data". This included process exports from Echoview software and calculated densities from echo integration (ha_integration.csv) and single target analysis (ha_single_targets.csv). Child Item 6: "Bioenergetics simulation data". This included simulated depth-distribution and daily thermal experience for all target species (optimal_depths_therm_exp.csv), daily outputs for annual simulations fit to observed final weights (daily_bem_outputs.csv), and outputs from the bioenergetics-based foraging model for juvenile Chinook salmon (foraging_model_output.csv).
