Backyard Aquaponics
A place to discuss aquaponics

Recently purchased a home with 3/4 acre spring fed outdoor pond in New England. Looking for ideas on how to suppliment mortgage with $$ generated from pond. Any low initial investment ideas?

Fill it with fish and charge people access or per fish caught.

you'll have to get a survey of your pond done to find out what's in it.. you need a forage base, and a predator or two to keep pest species under control...
find out what other people are growing in similar size ponds in your area.. you'll probably be able to raise a couple species to eating size, expecially if you supplement with feeding
i believe there are some folks from New England on the Pond Boss forum;
