How to Cleverly Identify Whether Fish Have Eaten Their Fill
1. Pay close attention to how long the fish take to eat at the feeding tray or feeding ground. If, after a certain amount of feed is put in (the normal feeding amount), the fish finish the feed in less than 2 hours, it means the feed is insufficient and some fish have not eaten or have not eaten their fill, so an appropriate amount should be added. If the feeding amount per ten-day period is fixed and the daily feeding amount within the period is the same, but by the end of the period the feed put in is finished by the fish in less than 2 hours, it means the fish have gained weight and the feed amount should be increased. When feeding compound pellet feed, if the feed has already been finished but the school of fish is still swimming rapidly on the surface layer searching for food and is unwilling to sink into the "second layer of water," it indicates the fish have not eaten their fill. If the school of fish has already dispersed from the feeding tray or feeding ground and there is still leftover bait, the fish have eaten more than their fill, and the feeding amount can be appropriately reduced next time.

Tests have shown that when the crude protein content in the feed is
