Investigating local substrates and supplements

I’m looking into vitamin and mineral supplementation. - What about formulated feed pellets with amendments? - Producers Pride 12% - SSF in tubes and extension rates for various substrate mixtures would be ideal (Philippoussis and Diamantopoulou 2015) - Gathering some other data on productivity besides just growth rate and BE? - crude protein, fat, carbohydrate assays? - C/N ratio - ash - water content

What to select for?

  • Ultimately appearance and fresh weight are primary factors affecting sale price (labeling may also contribute)
    • profit is based mainly on product weight per unit time less labor and substrate costs
  • Labeling: variations on how ‘Local’ (Burnett, Kuethe, and Price 2011)
  • Price Premiums: Local; Organic; Carbon-Footprint; (Onozaka and Mcfadden 2011)
