怎么样理解from livestock in fishing ？

VOA 《Turning Straw to Fuel to Save Senegal's Forests》

The initiative is diversifying the economy of a rual region where many eke out a living from livestock in fishing.

怎么样理解from livestock in fishing ？ 这里用from...in...怎么样理解？


将来类似的提问请附上原文的链接地址，以便核对原文。这种听写的文字有时会出现错误。单从本句看，eke out a living from sth, 意为靠...艰困难程度日/为生，所以in换成or, 靠养家畜或打渔勉强度日。则逻辑通顺。
