Of course it belongs to murder. What is the ultimate goal and result of your farming? Of course, it was sold to those slaughterhouses and eventually killed. Don't think it doesn't matter to you if you don't kill them. You sell them to the butcher, and you are as guilty as the butcher. Therefore, Buddhists should never engage in farming. And there will always be animal feed in the feed during the feeding process. You didn't kill this animal feed, but because it is your pleasure for livestock to eat animal feed, you also killed happily. Therefore, Buddhist disciples should not engage in aquaculture.
