NEMoW – Coupled NPZ-Fish Models


Major efforts within noaa

Major efforts within NOAA

  • NEMURO (North Pacific Ecosystem Model for Understanding Regional Oceanography) – Modeling Suite

    • NPZ model (NEMURO) dynamically linked to fish bioenergetics and population dynamics model

  • NPZ-Cal (NPZ linked to Copepod IBM for the California Current)

    • NPZ model driven by assimilated or observed physical data or environmental indices (e.g. upwelling index), which then serves as prey fields for more complex Calanus spp. individual-based model. Run in 1D (vertical )boxes covering various west coast locations. No fish yet.

  • DisMELS (Dispersal Model for Early Life Stages)

    • A coupled biophysical individual-based model that incorporates ontogenetic changes in early life stage parameters and simulates egg and larval dispersal under 3-dimensional (3D) oceanographic currents

  • CBWQM and FEM (Chesapeake Bay coupled Water Quality Model and Fisheries Ecosystem Model)

    • The Chesapeake Bay Water Quality modeling suite includes the linked Airshed Model, Watershed Model, Estuarine Hydrodynamic Model, Estuarine Water Quality Model, and Living Resources Model developed by the Chesapeake Bay Program (led by EPA). Chesapeake Bay Fisheries Ecosystem Model (using EwE) was developed by NOAA Chesapeake Bay Office. The modeling suites are linked using physical forcing functions.

NEMoW – Coupled NPZ-Fish Models


What are the data requirements

What are the data requirements?

  • HUGE for full validation: physical circulation, temperature, plankton abundances, fish population biomass, fish individual weights, fish diet and foraging rates.

  • If you’re lucky the physical modeling data and validation requirements have already been dealt with elsewhere.

  • So you’re still left with the typical multi-species data needs plus info on phytoplankton and zooplankton

Take home point

Take Home Point

  • Different NPZ-Fish modeling approaches have arisen across NMFS, and these approaches have been published and have had some value in providing management advice.

  • Development of an NPS-Fish model for a NMFS Ecosystem Modeling Toolbox may be useful
