Most Acadian households were self-sufficient, with families engaged in subsistence farming only for a few years while they established their farms. Very rapidly the Acadians established productive farms that yielded surplus crops that allowed them to trade with both Boston and Louisbourg. Farms tended to remain small plots of land worked by individual families rather than slave labor. The highly productive dyked marshlands and cleared uplands produced an abundance of fodder that supported significant production of cows, sheep and pigs. Farmers grew various grains: wheat, oats, barley, hops and rye; vegetables: peas, cabbage, turnips, onions, carrots, chives, shallots, asparagus, parsnips and beets; fruit: apples, pears, cherries, plums, raspberry and white strawberry. In addition they grew crops of hemp and flax for the production of cloth, rope, etc. From the rivers, estuaries and seas they harvested shad, smelts, gaspereau, cod, salmon, bass, etc., utilizing fish traps in the rivers, weirs in the inter-tidal zone and from the sea with lines and nets from their boats. The fishery was pursued on a commercial basis as in 1715 at the Minas Basin settlements, when the Acadian population there numbered only in the hundreds, they had "between 30 - 40 sail of vessels, built by themselves, which they employ in fishing" reported Lieutenant-Governor Thomas Caulfield to the Board of Trade. Charles Morris observed the Acadians at Minas hunting beluga whales. The Acadians also varied their diets by hunting for moose, hare, ducks and geese, and pigeon.
