Blade fish is a kind of marine fish with a long body and a knife shape. In the wild food chain, they mainly get nutrition by preying on other small fish, plankton and benthic invertebrates. In the artificial feeding environment, saury can accept a variety of food types, including small arthropods, algae, various fish feeds and flaky foods.
However, spirulina is not considered as the main food source of saury. Although spirulina is a nutrient-rich organism, not all fish will take it as their main food source. In the artificial culture of leaf fish, fish feed or other food types suitable for its taste are usually provided, instead of relying solely on spirulina as the main food.
It is worth noting that different kinds of fish have different living habits and food preferences. When choosing food suitable for fish, we should choose according to their ecological environment, habits and eating habits.
