November 30th, 2020 --- In the year 2050, Earth will have almost 10 billion humans who will eat over 500 billion kilograms of meat.
With land-based meat fraught with climate and environmental impacts, how much animal protein can be sustainably supplied by the ocean?
This week we speak with the University of Washington's Sustainable Fisheries’ Editor Max Mossler on what will be one of the most cited papers in the next decade.
'The future of food from the sea' (Costello et al. 2020) is an important paper that roadmaps improved fishery management and mariculture reform to produce as much animal protein from the sea that we can.
--- The demand our multi-billion global population puts on the planet for protein increases exponentially each year.
---- [Feed technology] The most sustainable way to grow fish is to use the least amount of food, or use food that is low impact.
right now a lot of the food that is fed comes from wild fisheries, which are reduction fisheries, like the Peruvian Achoveta which is all turned into fish meal and eventually become Salmon.
There is an environmental impact there, certainly compared to unfed mariculture, and there is a lot of research being done into how do we reduce the amount of wild fisheries that we feed to aquaculture species, can we use something that’s lower impact, can we feed them plants, insects or algae.
---- [Policy reform] (Explaining Graphs that will be shown on screen) Wild fisheries is on the left, Fed mariculture in the middle and unfed on the right.
This basically shows how much we, as a global society, could produce sustainably and what can get us to that sustainably.
for wild fisheries on the left, right now we produce a little over 50 Megatons of food and we can increase that to over 60 with some fisheries management reform around the world.
That’s how we could maximize the amount of sustainable wild fish that we get by reforming management.
The middle figure is showing fed mariculture, and how much edible production we could create by using policy reform, tech innovation which is highly ambitious.
Fed mariculture produces about 7 Megatons of food and we need to increase that, so using policy reforms gets us more, and with both that plus tech reforms like making fish farming more efficient with less feed, it goes to about 17 MT.
And if somehow we are able to reduce wild fish inputs into farmed fish by 95%, which is super ambitious, we could have well over 150 Megatones of food, which is more than enough protein to feed 10 billion people.
And on the right it shows unfed mariculture, which I'm such a fan of because all it requires is policy reform, the more policy reform that we have, the more seafood we get, and the limit does not exist.
You can see we only get 3 Megatones of food comes from unfed mariculture, but the potential for that is really high.
What’s really important about these is that there are price next to them, so supply of what is possible economically and one of the reasons this paper is so important is it doesn’t just show what’s possible biologically, it shows what's possible biologically under different price scenarios, which is much more realistic, so we have some realism with the science, which is really great."

--- As a company with a goal of promoting sustainable eating, we feel that it is our responsibility to shift consumer demand towards using seafood as your primary source for protein.
The seafood industry is leading the way for sustainable protein suppliers around the world to follow suit, and utilise the full potential of our oceans and resources that we have available, with much less impact than we are seeing now.
Not only will it benefit the environment, it's a healthier protein than red or white meat, and can still satisfy a hungry customer.
