>>1822570I only bring grains I can eat raw like rolled oats.
Potatoes weight a ton- you're just bringing in water.
You may try sowing millet, there are thousands of indigenous grains you can wild-sow and just collect whatever happens to come up.
The fat from fish is super carb dense, you can go for shore fish with a line or even a net if you have shallows.
If you have rock pools you can go for crustaceans.
It can be a dangerous business though with currents and the bad/infected cuts you can get.
But for the time you spend it's very productive, especially if you dry or ferment the fish.
I believe you can also purify fish oil and use it to preserve other products.
In some places people gather the eggs of wild birds or turtles- environmentalists would have a blue fit though because shorebird populations are often fragile.
Do you have Imazir that far south?
