What does saury eat? As a primitive carnivorous fish, saury can accept almost all kinds of food. Of course, artificial feed is not necessary, such as small fish and shrimp. Now it basically depends on the bait sold in the market. As far as the results of my investigation are concerned, feed fish and loach are cheap in the market. Shrimp is more expensive, fewer people buy it, and it is also troublesome to handle. Of course, it doesn't include the shrimp I went out to catch myself. Now feed fish is cheap and easy to handle, which is the choice of many fish farmers. There are also hamburgers made of red worms or loach, which are acceptable. One possibility is feed, and a small number of seven-star fish can accept feed, mainly parrot fish or turtle feed, so they basically grab food by themselves.
The food of the seven-star swordfish is mainly the above, of course, it is mainly not these. As long as it is acceptable to the seven-star swordfish, it depends on what the fish friends feed. Another point is that saury belongs to the bottom fish and rarely swims to the top to grab food. If it is polyculture, it is likely that it can't grab food, so the feed should be sunken as much as possible to facilitate the seven-star saury to eat.
