ISIS is now in control of fish farms in hundreds of lakes north of Baghdad, according to Iraqi judicial authorities. The fish farms are generating millions of dollars per month, officials say.

ISIS took over some of the farms when farmers fled, and others have agreed to work for ISIS.

A report by Reuters was based in part on information obtained from captured ISIS fighters. It notes that the group didn’t just turn to fish farming out of nowhere—Al Qaeda had used fish farms to raise money as early as 2007. Some of the money generated goes to paying ISIS fighters’ salaries, which include bonuses for having up to four children as well as special payments like the one fighters received after ISIS captured Mosul.
