1. The feed used for mullet is general intensive fish farming with floating granular materials, with crude protein content of 30%. Feed them once every morning and evening, and the feeding amount is 3% ~ 5% of the body weight of the pond fish. The specific feeding amount is based on the fact that they basically eat 25 minutes after feeding, and feed at fixed points in a box-shaped eating table surrounded by bamboo. Red-eyed trout has obvious habit of chasing food, and it is especially easy to feed and domesticate at fixed points, and it can be reduced from spraying and feeding to serving for 3 days.

2. In addition to feeding the floating pellet feed every day, combined with the feeding habits of the red-eyed trout, a certain amount of duckweed is raised or put in the pond every day to meet the demand of the red-eyed trout for green feed.
