Sure. Here's another way to look at it.
From Tony Bimbo's estimates of oil proportions comprising global marine oil in 2015 (%s can change depending on yearly quota & landings).
Fish body oils 53.29%
Anchovy oil 31.13%
Menhaden oil 8.15%
Capelin oil 8.15%
Herring oil 1.92%
Other 1.23% (fish liver oils .68%, squid oil .14%, krill .40%, shark oil .01%)
Single cell oils aren't factored into the above, because they haven't been a factor yet (years 2020-2030 should finally see expansion of this source into feed because some feed and farmers like the alt-source input story just like Beyond Meat or Impossible Foods (as opposed to old school FIFO- fish in, fish out), but an open question still how much & how successful)
Photo bio-reactors: (depends on each column/reactor set-up, but his assumptions seem reasonable enough)
If you assume these conditions:
Production: 2000 hours/year
Turnaround: 72 hours = 28 batches per year
50% lipid in the biomass
200 grams dry biomass per liter (1.7 lbs/gallon)
100 grams of oil per liter (.85 lbs per gallon)
---
Volume 100 cubic meters = 100,000 liters
= 280 mt of oil/year
Open ponds:
Area: 14 acres
= 280 mt oil /yr
