At present, there are mainly three ways to provide animal protein for the mariculture creatures: one is to feed the live bait directly, such as Artemia, rotifers and yeast; the second is to directly feed and catch in the natural sea area Fresh frozen low-value fish and shrimp; the third is fed to fish meal as the main source of animal protein produced artificial feed.
