Joint models for fish condition and density

It is possible to use VAST to fit models jointly to fish condition and biomass. I will post example data once a current paper is accepted for publication, but feel free to email me (James Thorson) directly to discuss the idea earlier.

Example applications:

  1. Index standardization
  2. Empirical Orthogonal Functions
  3. Ordination using joint species distribution model
  4. End-of-century projections
  5. Expand length and age-composition samples
  6. Combine condition and biomass data
  7. Expand stomach content samples
  8. Combine presence/absence, counts, and biomass data
  9. Seasonal and annual variation
  10. Combine acoustic and bottom trawl data
  11. Surplus production models
  12. Multispecies model of biological interactions
  13. Stream network models
